Embodiment Construction
[0040] Further illustrate the present invention below in conjunction with accompanying drawing:
[0041] see figure 2 , the specific linkage control system against the impact of industrial toxic pollutants is composed of three parts: pipe network monitoring system, linkage control system and in-plant control system. Their specific realization is as follows:
[0042] ①Pipeline network monitoring system
[0043] The pipe network monitoring system includes industrial toxic pollution monitoring points distributed in the drainage pipe network of the sewage plant service area, on-line monitors (pH meter and conductivity meter) and wireless data remote transmission equipment. The core of the technology is to use pH and conductivity as comprehensive indicators of industrial toxic pollutants to characterize the discharge and concentration of industrial toxic pollutants such as acid-base, heavy metals, and toxic organic substances in the pipeline network. At present, the most commonl...

The invention discloses an urban sewage treatment Orbal oxidation ditch industrial toxic pollutant impact resistance regulation and control system and relates to the technology for accepting the high-proportion industrial waste water Orbal oxidation ditch sewage plant industrial toxic pollutant impact resistance and maintaining the oxidation ditch sludge activity and the treatment efficiency. The pH and the conductivity are selected on the basis of toxicity relevance analysis results to be used as integral toxicity reflecting and early warning indexes, the toxicity early warning threshold value is determined on the basis of the Orbal oxidation ditch active sludge poisoning test analysis, the toxicity monitoring point is selected according to the pipe network characteristics, and an industrial toxicity pollution early warning monitoring and wireless remote transmission system is built. The Orbal oxidation ditch operation linkage regulation and control system linked with a pipe network monitoring system is built on the basis, the resistance of the Orbal oxidation ditch on the industrial toxicity pollutant impact can be enhanced through regulating the water inlet flow rate, the sludge reflux ratio and the aeration intensity, the biological activity in the ditch is maintained, and the sewage treatment efficiency is ensured.
Description
technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a control system for resisting the impact of industrial toxic pollutants in an Orbal oxidation ditch urban sewage treatment plant. It is suitable for the daily operation of the Orbal oxidation ditch sewage treatment plant (or treatment station) that receives a high proportion of industrial wastewater. Background technique [0002] The sewage in the urban drainage pipe network often contains toxic pollutants that are harmful to the biological treatment system of the sewage treatment plant. Most of these toxic pollutants come from industrial enterprises. In 2010, the discharge of industrial wastewater was 23.75 billion tons, accounting for 38% of the total discharge of urban sewage in my country. Moreover, due to the wide range of industrial enterprises involved, the nature of the wastewater discharged varies greatly, and the mate...
