Automatic control sewage treatment system with variable process and treating capacity

Abstract

Disclosed is an automatic control sewage treatment system with variable process and treating capacity. The system is characterized in that each group of sewage treating pond is divided into five cases, namely a regulating tank, a materialization tank, an anaerobic tank, an aerobic tank and a precipitation filter tank, in the same engineering project, a plurality of sewage treatment processes can be comprehensively utilized, due to the fact that 'methods are applied according to situation', sewage can be effectively treated, effluent water quality can reach the standard, one group or a plurality of groups of sewage treating ponds which are parallelly combined are utilized to treat the sewage simultaneously so as to adapt to the change of sewage treating capacity, the problem that a second-stage construction or a new project is required to be prepared caused by addition of treating capacity is solved, and extra investment is saved. According to the automatic control sewage treatment system with the variable process and treating capacity, a full process of sewage treating is automatically monitored and controlled, the treating time is saved, accurate treating data is obtained, on the premise of the lowest operating cost, the best treating effect is obtained, and the long-term stable operation of the sewage treating project can be guaranteed. Compared with conventionally sewage treating processes, the system has the advantages that the operating cost can be reduced by 30%-50%, the land can be saved by about 50%, and the one-time investment can be saved by about 30%.

Description

technical field [0001] The invention relates to an industrial wastewater and domestic sewage treatment technology, which belongs to the technical field of environmental protection, and in particular to a sewage treatment system with variable automatic control process and variable treatment capacity. Background technique [0002] The existing industrial wastewater and domestic sewage treatment technologies all determine the process method and treatment scale (processing capacity) at the time of plant construction design, and most of them use manual electric methods to add sewage treatment agents. Its disadvantage is that once the plant is built according to the design, its process method and sewage treatment capacity cannot be changed, but to change the treatment process and treatment capacity, it is necessary to design a new plant or expand it, resulting in an increase in investment costs and land area; moreover, manual control The reaction of adding sewage treatment agent b...

AI Technical Summary

Problems solved by technology

Its disadvantage is that once the plant is built according to the design, its process method and sewage treatment capacity cannot be changed, but to change the treatment process and treatment capacity, it is necessary to design a new plant or expand it, resulting in an increase in investment costs and land area; moreover, manual control The reaction of adding sewage treatment agent by electric method is slow, and accurate judgment cannot be made according to the change of water quantity and quality. It is difficult to control the dosage of more or less, so the operating cost is high and the water quality is unstable, which greatly affects industrial wastewater and life. Long-term normal operation of sewage treatment projects

Although automatic control devices are installed in some sewage treatment projects, the full automatic monitoring and control of the whole process of sewage treatment and multi-point implementation needs to be improved.
