Guizhou releases action plan for phosphorus pollution prevention and control

On April 7, the Guizhou Provincial Department of Ecology and Environment issued the "Special Action Plan for Deepening Phosphorus Pollution Prevention and Control in Guizhou Province" (referred to as the "Plan"), requiring further promotion of the pollution control of enterprises in the phosphorus chemical industry, consolidating and improving the Wujiang River, Qingshui River and other key river basins (regions).
) water environment quality, and build a strong ecological security barrier in the upper reaches of the Yangtze River
.

The "Plan" puts forward the main goals: by deepening the pollution control of phosphate rock, phosphorus chemical (phosphorus fertilizer, phosphorus-containing pesticides and yellow phosphorus manufacturing, etc.
) enterprises and phosphogypsum warehouses (hereinafter referred to as "three phosphorus") pollution control facilities, "three phosphorus" enterprise pollution control facilities The total phosphorus concentration in the effluent water body is stable and meets the relevant requirements for management and control, and the phosphorus pollution control system is gradually improved
.
The main tributaries of the Wujiang River, the Yangshui River, the Weng'an River, the Xifeng River, and the main tributaries of the Qingshui River, the Chong'an River, have stably reached the Class III water quality standard
.

The "Program" deploys 9 key tasks
.
First, optimize the industrial layout
.
Relying on mineral resources and existing industrial structure, build a phosphorus chemical industry cluster
.
The second is strict environmental access
.
Strictly implement environmental management and ecological environment access, and guide small and medium-sized phosphate mines with relatively backward technology and low resource extraction efficiency to gradually withdraw
.
The third is to promote industrial upgrading and transformation
.
The fourth is to further promote the comprehensive utilization of phosphogypsum
.
Taking acid production, phosphogypsum building materials and underground filling as the three main directions, we will promote the realization of comprehensive utilization and disposal rate of 100%
.
The fifth is to deepen the comprehensive rectification of phosphorus chemical enterprises
.
The sixth is to deepen the comprehensive improvement of phosphate rock
.
Promote the upgrading and renovation of sewage treatment facilities in phosphate rock mines, and strengthen the control of ground-source pollution on mining sites
.
The seventh is to deepen the comprehensive improvement of phosphogypsum slag field
.
Build and improve flood interception ditch, leachate collection pool and emergency pool,
etc.
The eighth is to deepen the treatment of phosphorus-containing wastewater
.
Strengthen the operation and supervision of the end-of-life treatment facilities in Jiaoyishan and other phosphogypsum slag fields of the Phosphate Group, and urge the Phosphate Group and other enterprises to upgrade and transform the original facilities
.
The ninth is to strengthen the safety of pollution control facilities during the flood season
.

Wang Mei, director of environmental protection of the Safety and Environmental Protection Department of Guizhou Phosphate Group, said that the current difficulties in phosphorus pollution control are mainly in two aspects: First, the phosphorus pollution control system is not perfect, and there are still phosphorus pollution in the face of unexpected abnormal weather and the expansion of industrial production capacity.
pollution risks; second, although breakthroughs have been made in the comprehensive utilization of phosphogypsum, the comprehensive utilization is still difficult due to input costs and market mechanisms
.
She said that phosphorus chemical enterprises should improve the proportion of fine phosphorus chemical products, optimize and eliminate outdated production capacity and technology, upgrade pollution control technology and equipment, coordinate the development of park-based environmental management and improve park access standards, strengthen the construction of environmental monitoring facilities, and develop phosphorus Measures such as new paths for comprehensive utilization of gypsum will further solve the problem of phosphorus pollution
.

Wang Mei said that Guizhou Phosphate Group will take the following specific measures
.
The first is to further realize clean production in all links from ore mining to final products; the second is to carry out environmental risk assessment of tailings ponds and phosphogypsum slag fields, scientifically carry out comprehensive utilization and harmless treatment of phosphogypsum, and reduce phosphogypsum The third is to speed up the completion of key environmental protection projects such as emergency treatment of Wujiang No.
34 Spring Gold Bridge, film laying of Jiaoyishan slag yard backwater reservoir, and comprehensive treatment of tailings pond
