In most sewage treatment plants also undertake the task of disposing industrial wastewater and domestic sewage, some water treatment plants due to the impact of influent, resulting in a few days of water quality exceed the average daily amount. So how to do a good job of water treatment process control work? Start with the following points! (Source: China Environment News)

Trace the Source

Finding accurate source traceability is the key to solve the problem. At present, the construction of water quality monitoring system for point sources of pollution sources needs to be further improved. While optimizing the application of the effectiveness data of online monitoring of the enterprise water process, the main pipelines around several decentralized pumping stations in the sewage treatment plant should be further covered by online monitoring equipment to facilitate accurate locking of regional locations and effective investigation. In addition, the ecological environment law enforcement department should scientifically determine the industry and region, determine the list of enterprises according to big data, and pay special attention to the raw and auxiliary materials involving acidic substances. By referring to the list of raw and auxiliary materials, verifying the wastewater treatment process and discharge situation, and tracing the source in combination with the production process, experts are invited to conduct comprehensive analysis, objectively evaluate the actual production and discharge situation of the enterprise, and effectively control the source to prevent the occurrence of stolen discharge, leakage and discharge.

Strengthen Emergency Response

In the case of influent impact, emergency measures should be taken and quickly disposed of in place. If the active bacteria community is affected instantly, measures such as increasing drug delivery and nearby transportation of activated sludge should be immediately launched to effectively resist the impact. In addition, sewage treatment plants should reduce their treatment capacity by adjusting the flow rate, using emergency pools to collect wastewater and other temporary measures to gain a time buffer for batch treatment.

Consolidate the Responsibility of Territorial Supervision

Compacting the main responsibility of pollution control enterprises, prompting them to independently improve management requirements, popularizing wastewater online monitoring equipment for sewage discharge outlets, and realizing real-time data networking. The territorial government can entrust professional social institutions to monitor the water quality of the discharge of key regulated enterprises from time to time to provide a scientific basis for investigation and daily supervision.

Effective Early Warning

For the sewage treatment plant affected by influent impact, the territorial government and local functional departments should face up to the problem, identify the crux, and effectively avoid such problems in the future work. Optimize project access, take green development as the principle, select high-quality projects, and eliminate projects with high energy consumption, high pollution and high emissions. Strengthen the construction of sewage network, optimize the online monitoring capacity of regional pumping stations, carry out exploration and drainage of dead spots and blind areas, and gradually refuse to directly discharge industrial wastewater into urban sewage treatment plants without pumping stations. Actively explore the construction of sewage centralized disposal points in small and medium-sized industrial parks, and improve the monitoring capacity of industrial wastewater treatment process.
