Putting water quality first and avoiding pollution

A small resident of Jinan may avoid the suspicion of meddling, regardless of the situation in the whole country or province. However, Jinan, within the spring area of Jinan, the water riots have directly and seriously damaged personal interests, and they have to speak up. Moreover, they only have to walk in the national machinery "freely". First, let's talk about urgent and preventive matters.

Firstly, the eastern route of the South to North Water Diversion must be prohibited from entering and no longer demonize the local infrastructure. Of course, if the Southwest Water Diversion Method is used to adjust the water quality, it can be combined to make the icing on the cake. But the premise is that there is a dedicated water line, pollution prevention is a major concern, and water quality is of utmost importance; The technique is optimized and improved, and the economy is worth it. Fat and rotten are not good for water.

Based on the unified research of regional hydrogeological four field and five dimensional holography, the Jinan Spring Area was delineated in 2015 as shown in the figure below, with an area of 7700 square kilometers.

According to the data from 1916 to 1980, the average annual precipitation in the working area is 550~1110 mm, with the largest at the top of Mount Taishan Mountain and the smallest in the Northwest Angle; The average annual precipitation representing approximately 60 meters of terrain height is 650 millimeters. According to personal observations at a height of 115 meters in the central spring area from 2002 to 2022, the average annual precipitation is 794 millimeters. Conservatively speaking, aboutThe karst water monoclinic system in the 4000 square kilometer Jinan spring area has an average annual precipitation of about 800 millimeters in the high potential precipitation transformation and supply area. The average daily precipitation conversion rate of 10%, 20%, 30%,... is about 880000 cubic meters, 175000 cubic meters, 263000 cubic meters, and..., among which there is a quota of 200000 spring landscape, with a lot of remaining space.

High level areas, mainly exposed areas of karst strata, can increase precipitation conversion rate through a systematic optimization combination of multiple sub projects based on the concepts of flood detention, flood detention and infiltration enhancement, and flood detention and water regulation. In the course of history, the relatively perennial spring water discharge in the western region, which has been particularly silted up, only remains at the Yufu Spring. It is located at the bottom of the Yufu River on the south side of the current Jingshi West Road, and is about 5 meters higher than the general spring point in the old urban spring area. The hydraulic slope of the main reservoir and the pressure tunnel system in the spring section is close to zero, and there is also a lot of room for adjustment and control to balance water supply and spring protection. Furthermore, due to the fact that the water in the Yufu Spring needs to pass through overflow or be obstructed by displacement, the water level potential at the spring mouth can generally be much lower than the water level potential of nearby karst water, or the adjustable turning margin on the water level is much greater than 5 meters, exceeding an annual variation of the general natural water level. It is the most favorable condition to stimulate resource increment or increase precipitation conversion rate.

Plain areas are relatively simple, and a type of engineering called deep flat permeable pipe drainage technology can be tested and promoted (slot opening, flat hole penetration, sand covered filter pipe, permeable filling work slot), which is suitable and effective in reducing water level, increasing precipitation infiltration, and also serving as a water intake irrigation, controlling water quality to fill the lower aquifer or motorized salt discharge, etc., to prevent or gradually improve salinization. It is definitely not difficult to reduce the cost. If the pipe is solidly cast with slag and wrapped with a filter layer, the cost will be lower. Choosing a corner that emphasizes quality control design and farming can also solve the problem of domestic water use nearby. There is no problem with underground self-sufficiency in the formation of general water resources, and in years of extremely dry precipitation, it can also be solved by nearby Yellow River diversion.

There are about 100 billion cubic meters of super high-quality karst underground reservoirs formed in the central and western regions, with unique formation conditions, such as a total mineralization of 0.3-0.4 grams per liter, which are the most favorable conditions for spring sources, flood control, and water supply regulation and storage.The karst underground reservoir is about 100 billion cubic meters, considering only water quality and degree of freedom. In terms of pure elastic release or incorporation into the functional body, it is far more than 100 billion cubic meters, and the entire spring area is no less than 400 billion cubic meters. This also delays the impact of precipitation on the water level in the spring area for several years.

The porosity of the main parameter for calculating the volume of underground reservoirs is calculated based on the core data of 1000 boreholes formed at random locations, and the general vacancy rate of the target layer is obtained. The vacancy rate is further reduced by half. Reducing the empty core rate by half can completely offset the possible mutual wear and tear between core nodes during the drilling process. As for the karstification rate of the visible rock core itself, i.e. the volume rate of pores and voids, due to the accuracy and proportion of measurement records, it is only considered for comprehensive evaluation, which also includes comparative analysis and so on.

Saying super high quality is because existing national standards cannot define it. As for the quality standards of groundwater, at least karst groundwater, fissure groundwater, and pore groundwater should be treated differently, rather than being single and general. Due to their different element and ion combination relationships and pollution mechanisms, they are not treated differently, let alone monitored and guaranteed mechanisms.

Talking about karst water resources aloneThe average annual precipitation of the relevant 4000 square kilometers in the supplementary area is about 800 millimeters. The system engineering control makes it easy to achieve a 20% conversion rate of precipitation resources, with an average of 1.75 million cubic meters per day; The cost of reaching 30% is much higher, but the average daily volume of 2.63 million cubic meters is also more attractive.Even if it's an average of 2 million cubic meters per day. 500000 cubic meters of high-quality water can be controlled. If it is specifically used for drinking water, Jinan people can provide 100000 cubic meters of water per person for free, which is enough to double the amount; 100000 square meters of low-priced supply to the periphery; The remaining 300000 cubic meters, whether Beijing and Tianjin want to drink them or not, are no less than ordinary mineral water, and the middle route water of the South to North Water Diversion is even more incomparable.This is the inherent advantage of Jinan's water resources, as long as the original ecology of the Yufu River, Beisha River, and Nansha River basins is not deliberately destroyed as it is now, or restoration and management are allowed, allowing for the existence of a "systematic engineering for the overall optimization of Jinan's spring water and water resources".

The general conditions for water quality and degree of freedom in the monoclinic karst water system can be found in two sub charts. The time-varying reference node for the zoning of total mineralization in 1990.

The Demon Waste in Jinan

The most basic principle of urban expansion in Jinan, in terms of original ecology, should be to relatively sacrifice the east and expand to the northwest, but it must be ensured that the west, including the entire Yufu River basin and the karst water recharge area in the west, can infiltrate, infiltrate and seep and its upstream source area. The Yufu River, Beisha River and Nansha River basins are particularly critical. This is determined by the existence conditions and main spring source conditions of a 100 billion cubic meter level originally super high-quality karst underground reservoir.

However,With the establishment and operation of the East Route of the South to North Water Diversion Project, Jinan has carried out a series of precise magic treatments for its own water resources and spring conditions.For example, Changqing District will be set up and expanded, including the forced relocation of small polluting enterprises that have no leakage pollution of karst groundwater in the original urban area of Jinan to the exposed and semi exposed areas of karst strata that are most likely to cause pollution in the district; Strengthening the construction of a university town in the key location of Beisha River; The upper reaches of the Yufu River basin have secretly established Nanshan District, strengthened the two towns, and will also build another Liubu City; Outsourcing Mashan Town in the upper reaches of the Nansha River Basin; The R1 line, which is the primary implementation of rail transit construction, is also the only major source water area in the Nansha River Basin that has not yet undergone serious deterioration due to its remote location, which is directly from rural areas to mountainous areas (almost two kilometers away). These are all considered obscure points. The blatant and widespread destruction began in 2006, with the first step being to lay anti-seepage membranes on the entire leaking area of the Beisha River to isolate and recharge groundwater. Other river management measures may also include burying membranes or cascade interception to promote evaporation.

Let's take a look at what the real East Route of the South to North Water Diversion is and what it doesThe following three screenshots are annotated based on their audio brief.

Simply put,The eastern route of the South to North Water Diversion Project, under the guise of "river water", has been plagued by pollution along the way, leading to the demonic waste of Jinan and Shandong.This includes the intention to completely pollute and destroy a 100 billion cubic meter level karst underground reservoir in Jinan, which was originally super high-quality (with unique formation conditions, such as a total mineralization degree of 0.3-0.4 grams per liter) and had the worst self-cleaning ability.

Not only that,New pollution enterprises in Jinan have moved to Laiwu to pollute Dongping Lake and increase the negative weight of water in the south of the east line, Wisdom Top, Roll Tai'an again. Tianjin City?
