How to check the circuit before using zero discharge of industrial wastewater? Author: With the serious water pollution, many factories in the production process generated waste water will be discharged via the standard post-treatment sewage treatment equipment. Start and check the circuit when the waste water is zero discharge, whether the wiring of the wiring control cabinet is correct, and whether the voltage and current meet the requirements. This control cabinet can control a submersible sewage pump and a waste water zero discharge fan at the same time, and is also equipped with manual and automatic control systems. When starting the water pump, check whether there is any leakage and water absorption in the water pump pipeline, and whether there is any blockage. 1. All kinds of zero-discharge waste water electrical equipment are equipped with short circuit and carrier devices, and indicator lights are set to show the working status of each electrical equipment. 2. The startup, shutdown and switching of all kinds of zero-discharge waste water electrical equipment are automatically linked by the programmable controller according to the program. At the same time, there is an automatic and manual switch on the panel of the control cabinet, which can be switched to manual control if necessary. . 3. The zero-discharge waste water fan generally needs to change the oil once after 6 months of operation to improve the service life of the fan. The zero-discharge waste water pump adopts the anti-clogging tearing submersible sewage pump. The control of the water pump is completed by the liquid level controller by detecting the liquid level in the sewage tank. When the liquid level reaches the working water level from low to high, the working pump is started, such as wastewater When the zero-discharge liquid level is low to the warning level, turn off the working pump, and check whether the rotation direction is correct when starting the fan, and do not reverse.
