A method for evaluating the operation performance of an industrial wastewater treatment system

Abstract

The invention discloses a method for evaluating the operation performance of an industrial wastewater treatment system, which includes the screening of benchmark pricing indicators. The benchmark pricing indicators include the first-level evaluation index treatment quality and the first-level evaluation index operation quality, and the treatment quality includes the second-level evaluation index waste water. Treatment capacity, effluent compliance rate, and effluent stability. The effluent stability includes the three-level evaluation index, the fluctuation range of suspended solids, the fluctuation range of total nitrogen, the fluctuation range of total phosphorus, the fluctuation range of ammonia nitrogen, and the BOD 5 Fluctuation range, COD fluctuation range, the operation quality includes the second-level evaluation index microbial activity, equipment reliability and operation economy, the equipment reliability includes the third-level evaluation index equipment saturation rate, equipment failure rate, average maintenance time of equipment, The operation economics include three-level evaluation indicators: power consumption cost per ton of water treatment, chemical consumption cost per ton of water treatment, labor cost per ton of water treatment, and equipment maintenance and repair costs. The invention can realize the comprehensive quantitative evaluation of the overall operating performance of the process system.

Description

A method for evaluating the operational performance of an industrial wastewater treatment system technical field The invention belongs to the technical field of waste water treatment, be specifically related to a kind of industrial waste water treatment system operation performance evaluation method Law. Background technique Industrial wastewater includes production wastewater, production sewage and cooling water, refers to the wastewater and Waste liquids, which contain industrial production materials, intermediates, by-products, and pollution from production processes that are lost with water thing. There are many kinds of industrial wastewater with complex components. Improper treatment of industrial wastewater can cause pollution of organic oxygen-demanding substances, chemical poisons Pollution, Inorganic Suspended Solids Pollution, Heavy Metal Pollution, Acid Pollution, Alkali Pollution, Plant Nutrient Pollution, Thermal Pollution, Pathogens body pollution, ...

AI Technical Summary

Problems solved by technology

[0003] The industrial wastewater treatment system is huge and complex, involving many links, equipment and material energy, which leads to many factors affecting the operation performance of the process system, including uncertain events, equipment operation fluctuations, and workers' operation level. However, the evaluation of operation performance has not been standardized Quantitative and quantitative methods lead to the inability to effectively predict the change of wastewater effluent quality. When the effluent is abnormal, it is impossible to quickly and effectively find the cause of the abnormality and deal with it in time, causing environmental pollution and affecting production efficiency.
