The "Dalian City Coastal Sea Water Quality Improvement Work Plan" was released, requiring 100% collection and disposal of sewage and garbage in fishing ports

The "Plan" proposes that by the end of 2025, the total nitrogen concentration of the 10 national examination river sections included in the "Provincial Coastal Sea Water Quality Improvement Work Plan" will have achieved negative growth compared with 2020. The 45 rivers that enter the sea continue to consolidate the results of reducing poor water quality, and the proportion of sections with excellent water quality has increased by 25% compared with 2023; the absolute value of total nitrogen concentration is higher, the total nitrogen concentration has rebounded greatly, and the total nitrogen concentration of the river sections that enter the sea in Pulandian Bay has dropped to lowest level since 2020. The proportion of the city's coastal waters with excellent water quality reached 97.8%.

Focusing on agricultural planting, livestock and poultry breeding, urban domestic sewage and key nitrogen-related industries, the "Plan" formulates and arranges 16 specific work measures in six aspects. Including strengthening the treatment and control of total nitrogen in key rivers entering the sea, carrying out investigation and traceability analysis of rivers entering the sea, formulating a refined management and control plan for river pollution, and strictly controlling total nitrogen emissions from existing pollutant discharge units. Implement agricultural and rural pollution control, strive to create a provincial-level rural domestic waste classification and resource utilization demonstration county, strengthen the prevention and control of pollution from livestock and poultry breeding, and achieve a resource utilization rate of livestock and poultry manure of more than 80% by 2025, and promote the prevention and control of agricultural non-point source pollution , by 2025, the coverage rate of soil testing and formulated fertilization technology for major crops will stabilize at more than 90%. Strengthen the operation and maintenance of rural sewage treatment facilities and stabilize the operation rate at more than 90% by 2025. Implement comprehensive management of key marine pollution sources, achieve full coverage of classified management of sewage outlets into the sea in the city by 2025, and achieve 100% collection and disposal rate of sewage and garbage in fishing ports. Accelerate the construction of urban environmental protection infrastructure and make up for the shortcomings of urban sewage collection pipe networks. By 2025, the centralized collection rate of urban domestic sewage will strive to reach more than 70%, and the county sewage treatment rate will reach more than 95%.

In terms of supervision, assessment and incentive policies, the "Plan" clarifies that the improvement of water quality in the city's coastal waters should be included as an important part of the municipal government's annual performance assessment and pollution prevention and control assessment. Assessment of task completion. We will further strengthen the supervision of the operation of sewage treatment facilities of key sewage discharge units, coordinate the environmental supervision and law enforcement of key industries that emit total nitrogen such as urban sewage treatment plants, industrial clusters, and livestock and poultry breeding, and effectively crack down on various illegal activities such as sewage discharge during the flood season. All regions should conscientiously study various projects and management measures to reduce total nitrogen in the Fuzhou River, and promote the solution of outstanding problems such as livestock and poultry manure, river garbage and sewage overflows in their jurisdictions, consolidate the results of total nitrogen reduction, ensure the completion of annual assessment tasks, and on this basis, continuously summarize and accumulate typical work experience that can be replicated and promoted, and form the "Dalian Model" for total nitrogen control in rivers entering the sea.
