Sewage treatment process optimizing operation method

Abstract

The invention relates to a sewage treatment process optimizing operation method. The method comprises the following steps of: establishing a sewage treatment process model and predicating outlet water quality of a sewage treatment system so as to obtain an outlet water quality predicated value of the sewage treatment system; establishing a dynamic optimizing control system; establishing an industrial poisonous water diagnosis and response system so as to produce an alarm for invasive industrial poisonous water; establishing a sewage treatment process remote monitoring and diagnosis system so as to transmit local real-time monitoring data of a sewage treatment plant to enterprise managers and upstream authorities for making decisions; establishing a testing laboratory management system so as to test and measure the water quality and industrial parameters in the sewage treatment process and then analyze various testing laboratory measurement data; and introducing the various testing laboratory measurement data into the dynamic optimizing control system so as to correct set values of sludge concentration and dissolved oxygen concentration. According to the invention, the automatic control level of the sewage treatment plant is enhanced, the energy conservation and consumption reduction in the sewage treatment process are achieved, the safety of sewage treatment is improved and the human resource cost of the sewage treatment is reduced.

Description

technical field [0001] The invention relates to a sewage treatment technology, in particular to a sewage treatment process optimization operation method. Background technique [0002] Our country is facing a water resource crisis, and the task of sewage treatment is urgent and arduous. At present, the operation of sewage treatment plants in my country is not good, and excessive energy consumption is an important bottleneck restricting the development of sewage treatment industry. According to the statistical analysis of the energy consumption status of 559 urban sewage treatment plants in my country in 2006 by the Institute of System Analysis of the Department of Environmental Science and Engineering of Tsinghua University, the current power consumption per ton of water in my country's urban sewage treatment plants is about 0.29 kWh, which is about 0.29 kWh in developed countries. The power consumption per ton of water of the national urban sewage treatment plant is twice th...

AI Technical Summary

Problems solved by technology

[0004] In recent years, the basic theory and treatment technology of sewage treatment have become more and more mature, but the optimization control technology of sewage treatment process is still lagging behind.

At present, the control level of sewage treatment plants in my country is relatively low, most of them use simple PID control or manual control, and there is almost no application of optimal control methods

On the other hand, the management level of my country's sewage treatment plants is low, which affects the operating efficiency of the sewage treatment system to a certain extent, increases unnecessary waste of energy and human resources, and thus increases the cost of sewage treatment
