The Ministry of Ecology and Environment issued the "Implementation Plan for the Special Investigation and Remediation Action for the "Three Phosphorus" of the Yangtze River"

Recently, the Ministry of Ecology and Environment issued the "Implementation Plan for the Special Investigation and Remediation of the "Three Phosphorus" in the Yangtze River" to guide 7 provinces (cities) including Hubei, Sichuan, Guizhou, Yunnan, Hunan, Chongqing, and Jiangsu to carry out centralized investigation and remediation.
According to the relevant person in charge of the Law Enforcement Bureau of the Ministry of Ecology and Environment, the "Plan" clarifies the overall requirements and work arrangements for the special investigation and remediation of the "Three Phosphorus" of the Yangtze River, which can be summarized as three priorities and five stages.
Among them, the "three key points" refer to phosphate rock, phosphate chemical industry and phosphogypsum storage.
Phosphate mine remediation aims to achieve the discharge of mine water to the standard, effectively control the dust in the mining area, and implement ecological restoration measures in the mine.
Phosphorus chemical remediation focuses on diversion of rain and sewage, effective collection and treatment of initial rainwater, completion and normal operation of pollution prevention facilities, and discharge of wastewater up to standards.
Among them, phosphate fertilizer companies focus on the construction of sewage treatment facilities and the effective reuse of wastewater; focus on phosphorus-containing pesticide companies Strengthen the recovery and treatment of mother liquor; Yellow phosphorus enterprises focus on implementing "zero discharge" of elemental phosphorus wastewater and measures to prevent the loss of yellow phosphorus.
The improvement of the phosphogypsum reservoir focuses on the regular monitoring of groundwater, the effective collection and treatment of leachate, the standardized construction of return ponds, flood ditch and flood drainage canals, and the comprehensive utilization of phosphogypsum.
"Five stages", that is, the five stages of "checking problems-setting plans-school list-supervising progress-verifying effectiveness".
The first is the troubleshooting stage-to check the problems, organize and carry out the "three phosphorus" problem investigation, master the list of problems, and sort out industry models.
The second is the stage of classified rectification-to determine a plan, formulate a “one enterprise, one policy” rectification plan, form a rectification ledger, carry out rectification by classification, and draw a bill to advance the rectification task.
The third is the stage of checking and filling vacancies-school checklist, strengthened supervision, checking the question checklist and rectification plan, checking for missing and filling vacancies, checking concealment and omission, and completing the rectification of the yellow phosphorus enterprise.
The fourth is the supervision and promotion stage-supervise the progress, verify the rectification situation, supervise the rectification and improvement, cancel the rectification tasks that have been completed, and complete the rectification of phosphate rock, phosphate fertilizer enterprises, and phosphorus-containing pesticide enterprises.
Fifth is the verification and acceptance stage-nuclear effectiveness, continue to promote the rectification of key phosphogypsum reservoirs, continuously solve outstanding problems, and verify and accept the actual effects of the "three phosphorus" special investigation and remediation actions.
  The relevant person in charge of the Law Enforcement Bureau of the Ministry of Ecology and Environment pointed out that the special rectification action of the Yangtze River "Three Phosphorus" is an important battle on the battlefield of the "Yangtze River Protection and Restoration Battle".
Focus on solving prominent ecological and environmental problems in the "three phosphorus" industry, such as heavy pollution, high risks, and serious violations of laws and regulations.
