On November 10th, the Central Fifth Ecological Environmental Protection Inspector Group conducted an on-site inspection of the comprehensive treatment of total phosphorus pollution in the Yangshui River Basin of Kaiyang County, Guiyang City. It was found that the relevant rectification work in Guiyang City and Kaiyang County was perfunctory and payable, only focusing on the end management, and no problem was solved from the root cause, and the total phosphorus pollution was still outstanding. Guizhou Province reported that the problem of total phosphorus pollution in Yangshui River has been rectified In August 2017, the first round of central environmental protection inspectors reported to Guizhou Province that the total phosphorus pollution in the Wujiang tributary of Guiyang City was serious, and the total phosphorus pollution of the Yangshui River could not be solved for a long time. Guizhou Province's rectification plan requires to curb the rebound trend of total phosphorus pollution in the waters of the Wujiang River Basin. The concentration of total phosphorus in the waters of the Wujiang River and the Yangshui River has been reduced. The water quality target has been achieved according to the requirements of the “Water Ten†assessment; It is required to implement mine pit water treatment for phosphate mine enterprises in the Yangshui River Basin, improve and improve the level of automation control technology, and establish standardized management facilities construction and operation file accounts. Guiyang City's rectification plan also requires that the Kaiyang County People's Government accelerate the rectification of the Yangshui River Basin and improve the water quality of the Yangshui River. During the “reviewâ€, the rectification of the total phosphorus pollution problem in Yangshui River in Guizhou Province was reported as completed. Construction of flocculation and phosphorus removal facilities surface rectification "Flocculation and pollution control", surface rectification. In April 2017, Kaiyang County invested 9.847 million yuan to construct flocculation and dephosphorization facilities in front of the Yangshui River and Tangkou monitoring sections. About 26 million operating costs were invested each year, and the Yangshui River was reduced into Wujiang by directly adding flocculants. The total phosphorus concentration before the main stream seems to have reached the rectification target from the monitoring data of the section. The monitoring data of the flocculant section can be controlled between 0.19mg/L and 0.3mg/L, and the water quality is controlled in Class III to IV. between. However, from the situation of on-site inspection, although the total phosphorus concentration in the Tangkou section before entering the mainstream of the Wujiang River was reduced, the actual total phosphorus remained in the river channel after being settled by the flocculant, and it was not effectively removed. When the amount of water is relatively low, the deposited phosphorus pollutants will still rush into the mainstream of the Wujiang River, and the problem of total phosphorus pollution in the Yangshui River has not been effectively solved. Relaxation requirements, perfunctory. After investigation, it was investigated that the rectification and rectification involved 7 phosphate mining enterprises and a phosphorus chemical enterprise in the Yangshui River Basin of Kaiyang County, but the rectification work did not implement the requirements of the Guizhou Province rectification plan, and did not follow the “one mine and one facility†regulation. Instead, the original pollution control facilities were reincorporated into the rectification content, and “new bottled old wine†caused the problem of total phosphorus pollution not to be controlled or reduced. On February 13th, 2017 and February 21st, 2018, Kaiyang County issued the “Development Plan for Comprehensive Environmental Management of Yangshui River Basin in Kaiyang County†and “Work Plan for Long-term Management of Yangshui River in Kaiyang Countyâ€, only required. The phosphate rock mining company completed the mine water treatment and emergency remediation project. The seven phosphate mining enterprises only required to ensure the normal operation of the equipment and facilities, and the total phosphorus emission index of the characteristic pollutants was controlled below 0.2 mg/L. However, as of this “reviewâ€, only the phosphate rock fertilizer company built 80,000 tons of pit water treatment facilities in 2017, and the other six phosphate mining enterprises have not built new treatment facilities. The original facilities are difficult to guarantee the treatment effect. Since March 2017, Kaiyang County has carried out 28 supervisory monitoring of 8 outlets of phosphate mine enterprises. The total phosphorus index exceeded the requirement of 0.2 mg/L for local rectification, 22 times, accounting for 79%. Insufficient attention and pollution remain. The total phosphorus in the background of the Shuangdigou in the source of the Yangshui River has remained at around 0.1 mg/L for a long time. However, since July 2018, the total phosphorus concentration has risen linearly. The total phosphorus monitoring data from July to October is 6.5 mg/L and 7.16 mg, respectively. /L, 7.43mg/L, 10.45mg/L, which is 33.8 times higher than the Class IV standard (0.3mg/L) required for water function zoning. In this case, Kaiyang County did not pay much attention to it. As of the "review", the problem of excessive phosphorus exceeding the standard in the upper reaches of the Yangshui River has not been studied and taken. In addition, due to total phosphorus pollution, the water quality of the Yangshui River Basin in Kaiyang County has been poor for a long time. In 2017, the annual average water quality of the five monitoring sections was inferior to V; from January to October 2018, except for the Tangkou section. The flocculation and dephosphorization facilities changed the water quality of the section from the inferior V to the IV, and the water quality of the other three sections was still inferior. Kaiyang County Party Committee, the government listened to it, relaxed requirements The party committee and government of Kaiyang County did not fulfill the responsibility of rectifying the main body. There was no systematic consideration to fundamentally solve the problem of total phosphorus pollution in the Yangshui River Basin, and the “shortcut†in the rectification and the long-term pollution problem of the phosphate mine enterprises in the Yangshui River Basin. Instead of taking effective measures, let it go and relax. In this regard, the inspector team will further investigate and verify the relevant situation, and require the local authorities to rectify the situation and resolutely investigate and deal with the existing problems.
