To implement President Xi Jinping's strategic deployment of "jointly promoting large-scale protection and not large-scale development" of the Yangtze River Economic Belt, and to meet the overall requirements of the Yangtze River protection and restoration campaign, addressing the issue of severe total phosphorus exceedance in some river sections of the Yangtze River Economic Belt, and eliminating significant water environment hazards caused by some phosphorus-related enterprises,
The Ministry of Ecology and Environment recently issued the "Yangtze River 'Three Phosphorus' Special Investigation and Rectification Action Implementation Plan," guiding seven provinces (cities) including Hubei, Sichuan, Guizhou, Yunnan, Hunan, Chongqing, and Jiangsu to conduct concentrated investigations and rectifications.
A relevant official from the Enforcement Bureau of the Ministry of Ecology and Environment introduced that the “Plan” clarifies the overall requirements and work arrangements for the Yangtze River “Three Phosphorus” special investigation and rectification action, which can be summarized into three key points and five stages.
The three key points refer to phosphate mines, phosphorus chemical industries, and phosphogypsum stacks.
Phosphate Mine Rectification aims to achieve standard discharge of mine water, effective dust control in mining areas, and implementation of ecological restoration measures in mines.
Phosphorus Chemical Industry Rectification focuses on achieving rainwater and sewage separation, effective collection and treatment of initial rainwater, construction and normal operation of pollution prevention facilities, and standard discharge of wastewater. For phosphate fertilizer enterprises, the focus is on the construction of sewage treatment facilities and effective reuse of wastewater; for phosphorus-containing pesticide enterprises, the focus is on the recovery and treatment of mother liquor; for yellow phosphorus enterprises, the focus is on achieving “zero discharge” of phosphorus-containing wastewater and implementing yellow phosphorus loss prevention measures.
Phosphogypsum Stack Rectification focuses on regular groundwater monitoring, effective collection and treatment of leachate, standardized construction of return water pools, flood interception ditches, and flood discharge channels, and comprehensive utilization of phosphogypsum.
The “Five Stages” are “Identify Problems - Formulate Plans - Verify Lists - Supervise Progress - Assess Effectiveness.”
Identify Problems: Organize the investigation of “Three Phosphorus” issues, grasp the problem list, and sort out industry typologies.
Formulate Plans: Develop rectification plans for each enterprise, form rectification ledgers, carry out classified rectifications, and promote rectification tasks with a list-based approach.
Verify Lists: Conduct enhanced supervision, verify problem lists and rectification plans, identify and fill gaps, check for underreporting or misreporting, and complete rectifications for yellow phosphorus enterprises.
Supervise Progress: Verify rectification status, supervise rectification progress, delist completed rectification tasks, and complete rectifications for phosphate mines, phosphate fertilizer enterprises, and phosphorus-containing pesticide enterprises.
Assess Effectiveness: Continuously promote the rectification of key phosphogypsum stacks, continuously address prominent issues, and verify and accept the effectiveness of the “Three Phosphorus” special investigation and rectification action.
As a high-tech enterprise focused on the research and development of high-performance adsorbents, catalysts, and their process applications, Jiangsu Haipu Functional Materials Co., Ltd. provides specialized adsorbent materials with significant advantages for the treatment of phosphorus-containing wastewater.
Phosphorus Chemical Industry Wastewater Treatment
Haipu’s Advantages
Efficient removal of phosphorus from wastewater, with a high removal rate, suitable for pre-treatment before biochemical processes or end control after biochemical processes.
Low investment, low operating costs, mature and leading technology, and no secondary pollution.
Modular components with a high degree of automation and simple operation.
Examples of Our Phosphorus-Containing Wastewater Treatment Projects
Phosphorus-Containing Wastewater Treatment Project for a Biochemical Enterprise
This enterprise produces 65 tons/day of phosphorus-containing wastewater. The specialized adsorbent materials provided by our company can remove most of the phosphorus from the wastewater. The treated water then enters the biochemical system for further treatment, reducing the operational pressure on the biochemical system and controlling the phosphorus content in the effluent to meet discharge standards.
Phosphorus-Containing Wastewater Treatment Project for a Chemical Enterprise in Jiangsu
This enterprise produces 100 tons/day of phosphorus-containing wastewater. After pre-treatment to reduce inorganic salts in the wastewater, our specialized adsorbent materials are used to treat the organic phosphorus in the wastewater, meeting the enterprise’s requirements after treatment.
Phosphorus-Containing Wastewater Treatment Project for an Electroplating and Coating Enterprise
For an electroplating and coating enterprise producing 200 tons/day of phosphorus-containing wastewater, we designed a process to deeply remove phosphorus elements from the wastewater. The total phosphorus content in the treated effluent can be stabilized below 1 mg/L, meeting the enterprise’s requirements, and the treated effluent can be directly discharged.
Phosphorus-Containing Wastewater Treatment Project for a Chemical Enterprise
For a chemical enterprise producing 100 tons/day of phosphorus-containing wastewater, we designed a process to remove phosphorus elements from the wastewater using a combination of “oxidation + adsorption” treatment. The total phosphorus content in the treated effluent can be reduced to below 10 mg/L, meeting the enterprise’s requirements, and the treated effluent can be directly discharged after neutralization.
Phosphorus-Containing Wastewater Treatment Project for a Pesticide Raw Material and Formulation Enterprise
A company engaged in the research, production, and sales of pesticide raw materials and formulations produces phosphorus-containing wastewater during its production process. Our company uses specially designed nano-adsorbent materials to adsorb and separate phosphorus-containing organic matter from the wastewater. The phosphorus content in the treated effluent is significantly reduced, meeting environmental discharge standards.
The successful operation of these projects has accumulated experience for Haipu in the treatment of wastewater in the “Three Phosphorus” industry and will allow Haipu to contribute to solving the prominent ecological and environmental issues of heavy pollution, high risk, and serious violations in the “Three Phosphorus” industry.
