Under construction, Yijiang Qingshui is just around the corner
Guizhou Kai Phosphate Fertilizer Co., Ltd.'s Wujiang No. 34 Fountain Source Treatment Project-Jiaoyishan Phosphogypsum Yard Source Leakage Sewage Treatment Project undertaken by Guizhou CRRC Green Environmental Protection Co., Ltd. is another important project obtained by the company in the Kaifeng Group through competitive bidding .
According to the spirit of the document "Issuance of the" Implementation Plan for the Implementation of the Rectification of the Feedback Issues of the Fourth Inspection Team of the Central Inspection Team of Kai Phosphorus Group "", Guizhou Kai Phosphate Fertilizer Co., Ltd. plans to adopt a "near-source interception" in the northeast of Jiaoyishan Phosphogypsum Slag Yard "Drainage" measures, the establishment of interception and drainage section, improving the efficiency of intercepting sewage, reducing the cost of Wujiang 34 spring treatment, minimizing the pollutant content of sewage, so that the total phosphorus content of Wujiang 34 spring reaches the target set by the provincial government. Through demonstration, the work goal is to increase the current 200-300m 3 / h pumping capacity to 500-600m 3 / h, which is expected to reduce the total phosphorus in the 34th spring sewage to less than 50PPm. Since the current sewage treatment device cannot meet the 500-600m 3 / h treatment capacity requirement, a 600m 3 / h sewage treatment device needs to be simultaneously constructed. Considering that the general calcium phosphate wastewater treatment method has a high cost, and a large amount of sludge residue will be stored after the treatment, Guiyang Kai Phosphate Fertilizer Co., Ltd. plans to invest in Guiyang Kai Phosphate Fertilizer Co., Ltd. through process tests and water balance structure in the production area. Wujiang No. 34 Fountain Source Treatment Project-Wastewater Leakage Treatment Project at the Source of Jiaoyishan Phosphogypsum Yard. Through the use of pretreatment + ultrafiltration + RO reverse osmosis technology, the phosphorus and fluorine in wastewater can be reused and turned into waste. The concentrated phosphorus and fluorine-containing concentrated water is recovered and used in a phosphoric acid extraction device. Water is reused.
Through the implementation of this project, the water environment quality of Wujiang River will be improved. With the construction of this project, the current situation of the sewage leaking directly from Wujiaoshan phosphogypsum storage yard into Wujiang River will be changed. Environmental capacity creates conditions for sustainable regional socio-economic development. The completion of the project will improve the water quality of Wujiang River, and its beneficiaries are surrounding residents, tourists and aquatic resources.
The construction of this project is conducive to the improvement of Wujiang water quality and meets the requirements of the Guizhou Provincial Government's Wujiang River Basin Water Quality Standards Program, which “explicitly requires all localities to accelerate the treatment of phosphorus-related pollution sources and ensure that the water quality of the Wujiang Mainstream Control Unit achieves stable water quality”. It is conducive to improving people's production and living environment, and has huge social benefits.
