Automatic control method for urban sewage treatment and control system thereof

Abstract

The invention discloses an automatic control method for urban sewage treatment. The automatic control method comprises the following steps of (1) setting an intelligent monitoring main station; (2) setting a data analysis station and a database server; (3) setting a mechanical pretreatment substation, a biochemical treatment substation, a sludge concentration substation and a sludge dehydration substation which are connected with the data analysis station respectively; and (4) when the workstations are in a working condition, making each substation transmit respective acquired data information to the data analysis station respectively, matching and analyzing the received data information and parameter data information preset in the database server and transmitting the obtained analysis result to the intelligent monitoring main station by using the data analysis station, transmitting a corresponding adjusting command to each substation according to an analysis result by using the intelligent monitoring main station, and adjusting and acquiring once again by using each substation to realize real-time, circular and optimal control of each substation by the intelligent control main station. The invention further discloses a control system for implementing the method.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an automatic control method for urban sewage treatment and a control system thereof. Background technique [0002] With the growth of the national economy and the enhancement of public awareness of environmental protection, sewage treatment automation technology has ushered in unprecedented opportunities for development. [0003] However, the existing sewage treatment control system simply requires the concentration of dissolved oxygen and the denitrification of sewage to reach the predetermined target, but there is no overall protection measure for sewage treatment equipment, resulting in the sewage treatment equipment working at higher than the maximum power for a long time state, resulting in a greatly shortened service life of sewage treatment equipment, and when it stops working, it will cause some untreated sewage to be discharged without treatment, which will have a greater...

[0003] However, the existing sewage treatment control system simply requires the concentration of dissolved oxygen and the denitrification of sewage to reach the predetermined target, but there is no overall protection measure for sewage treatment equipment, resulting in the sewage treatment equipment working at higher than the maximum power for a long time state, resulting in a greatly shortened service life of the sewage treatment equipment, and when it stops working, it will cause some untreated sewage to be discharged without treatment, which will have a greater impact on the environment

In addition, after the sewage treatment is completed, the obtained sludge and the biogas generated in the process cannot be fully utilized.
