Introduction to the installation technology and characteristics of the zero discharge of acid wastewater? Author: Acidic waste water zero discharge newly installed user does not know how to operate, blind operation will cause some unnecessary trouble. Here is a detailed introduction to the operation of zero discharge of acidic wastewater after installation. 1. The installation and commissioning personnel must first open the water inlet valve and the water outlet valve, start the water in the equipment, lift the pump up, and transport the sewage from the regulating water tank to the beginning of the treatment equipment. 2. For the initial use and commissioning of the equipment, the drone manufacturer with zero discharge of acidic wastewater will turn off the pumping water when the water level reaches 1/2 height, open the fan inlet valve, turn on the fan, slowly open the fan outlet valve, and touch The oxidation tank is ventilated for 48 hours, and water is pumped to increase the participation of the pump in the equipment by 3/4. 3. The staff should touch the fuel inlet with their hands to see if it is sticky. At the same time, study the growth of microorganisms in the water until a yellow biofilm grows on the filler, the sewage is continuously transported to the equipment, and the water volume is gradually increased to the design water volume. 4. Investigate the growth of microorganisms in the water in time, and control the water intake in time if abnormalities are found. It is necessary to study the flow pattern of the secondary settling tank. 5. Mud should be discharged every 24 hours. The method to increase the sludge from the secondary settling tank to the sludge tank by opening the mud valve and pumping air when the mud is discharged is introduced. 6. The zero discharge of acidic wastewater should be added to the disinfectant (chlorine tablets, etc.) in the disinfection tank as required. The effluent from the secondary sedimentation tank is partially dissolved in the metering tank of the sterilizer to achieve the purpose of disinfection. After the treated water stays in the clean pool for about 0.5 hours, the zero discharge of acidic wastewater meets the discharge requirements and can be discharged through the water body. 7. After the commissioning of zero discharge of acidic wastewater is normal, the system starts. Because the electric operation control cabinet adopts PLC's active control program, the operation of pumps and fans are switched to effective operation status on the spot. 8. The user should check the quality of the discharged water at any time according to the requirements of environmental discharge to ensure the normal operation of the buried acidic wastewater with zero discharge.
