Embodiment

[0035] An integrated automatic control device for sewage treatment equipment, such as figure 1 Shown: Shows seven main loops of QF1-QF7. Supply blower, water pump, PLC, lighting, socket and dosing pump, DC 24V power supply and backwash water pump respectively.

[0036] Such as figure 2 Shown: QF8 and QF9 respectively provide instrument power supply, fan, control room lighting and other power supplies.

[0037] Such as image 3 Shown: circuit breakers QF1~QF5, inverters VFD1~VFD2, thermal relay RJ1, fluorescent lamps and spare sockets. The lower end of QF1 is connected to the incoming line end of Siemens inverter VFD1, the outgoing line end of VFD1 is connected to terminals U1, V1, W1, and the terminal is connected to the three-phase motor of blower 1 of electrical equipment.

[0038] The lower end of QF2 is connected to the incoming line end of Siemens inverter VFD2, the outgoing line end of VFD2 is connected to terminals U2, V2, W2, and the terminal is connected to the t...

Abstract

The invention relates to an automatic control device of an integrated sewage treatment device. The automatic control device comprises a PLC, a three-phase four-wire power supply, a main circuit breaker and nine branch circuit breakers. One end of each of the nine branch circuit breakers is connected to the three-phase four-wire power supply through the main circuit breaker, the other end of each of the nine branch circuit breakers is connected to each electric device and a power supply, the third branch circuit breaker is connected with a water supply pump through the normally open contact ofa first alternating current contactor, the seventh branch circuit breaker is connected with a backwashing water pump through a normally open contact of a second alternating current contactor, the ninth branch circuit breaker is connected with a control room fan and a lighting power supply through the normally open contact of a third alternating current contactor, and coils of the first alternatingcurrent contactor, the second alternating current contactor and the third alternating current contactor are connected to a control loop. Compared with the prior art, two air blowers can be standby for each other; and moreover, the PLC and the frequency converter are used for controlling the air blowers, dissolved oxygen data can be set, and automatic control over dissolved oxygen is achieved.

Description

technical field [0001] The invention relates to a control device for sewage treatment equipment, in particular to an integrated automatic control device for sewage treatment equipment. Background technique [0002] Qingshuiyuan's integrated domestic sewage treatment device concentrates units with different treatment functions in the same biological reaction tank, such as anoxic zone, aeration zone, sedimentation zone, non-clogging filtration zone, disinfection zone, and even sludge concentration tank They are all built together in the same reaction tank, which can save a lot of tank capacity, land occupation and pipelines. The overall equipment organically combines the above-mentioned different process units to show the integrity and coordination of the process. [0003] In order to realize automatic control of sewage treatment equipment, it is necessary to design an integrated automatic control device for sewage treatment equipment. The control equipment controlled by this...
