Abstract

The invention relates to an automatic control device of MBR integrated sewage treatment equipment. The automatic control device comprises a PLC, an Ethernet switch, a touch screen and a power supply for supplying power to the whole device, wherein the PLC is connected with the touch screen through the Ethernet switch. The automatic control device further comprises a main loop and a control loop, wherein the main loop comprises a three-phase four-wire power supply, a main circuit breaker and a plurality of driving branches which are connected in sequence, and each driving branch comprises a branch circuit breaker, an alternating current contactor and a driving part which are connected in sequence; the control loop comprises a plurality of control branches and is connected to the power supply, and each control branch comprises an intermediate relay and an alternating current contactor which are connected in sequence; and the output terminals of the PLC are respectively connected with theintermediate relays, and input terminals of the PLC controller are respectively connected with the alternating current contactors. Compared with the prior art, automatic control over the whole systemis achieved, safety and reliability are achieved, and operability is high.

Description

Technical field [0001] The invention relates to the field of MBR integrated sewage treatment equipment, in particular to an automatic control device of MBR integrated sewage treatment equipment. Background technique [0002] The integrated MBR domestic sewage treatment device adopts the technological process of grid well, regulating tank, anoxic, aerobic, MBR membrane tank, and disinfection tank. The above-mentioned hypoxia, aerobic, MBR tank and disinfection tank process units are organically combined to form a whole, which can save tank capacity, land occupation and pipelines. It shows the integrity and coordination of the craft. [0003] When anoxic and aerobic are mainly used to remove nitrogen, the basic process flow is as follows Figure 17 Shown. The co-built reactor saves capital construction and operating costs and easily meets the requirements of the treatment project for carbon source and alkalinity. [0004] Membrane bioreactor (MBR) water treatment technology is an eff...
