Wastewater treatment system based on discharge capacity and pollutant holding capability equalization regulation and control network

Abstract

The invention relates to a sewage treatment system based on a balanced control network of discharge volume and pollution-holding capacity. The discharge side is composed of pollution-producing nodes, pollution-reducing nodes, and sewage-discharging nodes, and the receiving side is a receiving water body; the sewage generated by the pollution-producing nodes is reduced After the pollution node is treated, it is discharged into the receiving water body through the sewage node. The number of pollution producing nodes, pollution reducing nodes, sewage nodes and receiving water bodies are all plural; On the basis of the hydraulic connection of the process, the nodes of pollution production, pollution reduction and sewage discharge can be generalized and integrated according to the actual situation. Based on the balanced regulation network of pollutant discharge and water body pollution-holding capacity, different regulation methods can be optimized to rationally allocate different In order to realize the distributed water pollution control network system combining source control, process control and terminal treatment, the analysis of the pollution-holding capacity of the water body in the basin is more accurate, and the water body pollution can be reasonably and effectively regulated.

Description

technical field [0001] The invention relates to a sewage treatment network, in particular to a sewage treatment optimization system based on a balanced control network of discharge volume and pollution holding capacity. Background technique [0002] Wastewater treatment: the process of purifying sewage to meet the water quality requirements for drainage or reuse. Sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Sewage treatment has been widely used in various fields such as industry, agriculture, transportation, energy, environmental protection, etc., and it has increasingly entered the daily life of ordinary people. [0003] Facing the increasingly scarce water resources, the water pollution load has increased sharply, leading to increasingly prominent water security issues. A large amount of industrial and domestic sewage is directly discharged into the water without treatment, and the extensive use of chemical fertili...

Problems solved by technology

The discharge of sewage often involves multiple industries and multiple channels, and it is difficult to achieve the goals of sewage utilization and discharge water quality only by relying on one-time sewage treatment or sewage treatment in a single industry

Especially at present, in a region, sewage treatment has failed to establish the hydraulic connection between various pollution production, pollution reduction, sewage discharge nodes and receiving water bodies, and has failed to achieve a balanced regulation of discharge volume and pollution-holding capacity, resulting in some areas The sewage discharge capacity of some areas is idle, and the lack of sewage discharge capacity in some areas can also alleviate the shortage of water resources to a certain extent.

At the same time, the existing research only calculates the amount of pollutants discharged into the river, and it is difficult to achieve the reduction of pollutants and the treatment of the water environment by relying on terminal treatment.
