Zero livestock wastewater discharge in the course of debugging and maintenance of the article: With the increase of livestock, the more serious pollution, zero emissions now use livestock waste has become a trend, a number of new users in the use of livestock wastewater In the zero-emission process, equipment failures are often caused by improper operation. Today, I will explain the precautions for the zero-discharge operation of livestock and poultry farming wastewater. 1. When starting zero discharge of livestock and poultry breeding wastewater, check the circuit, whether the wiring of the control cabinet is correct, and whether the voltage and current meet the requirements. The zero discharge control of livestock and poultry breeding wastewater is automatic control, using time relay control, and output using AC contactor. This control cabinet can simultaneously control submersible sewage pumps and fans, and combined with real-time monitoring of working conditions, has automatic protection functions, and is equipped with Manual and automatic control system. 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. 2. The zero-discharge water pump for livestock and poultry breeding waste water stops running. Check whether the water inlet of the water pump is blocked by garbage or sludge. If it is not possible to notify the construction unit for maintenance, it may be that the water pump is damaged or the electronic control unit is damaged. 3. The zero-discharge of livestock and poultry breeding wastewater pump adopts anti-clogging tearing submersible sewage pump. The control of the pump is completed by the liquid level float valve by detecting the liquid level in the sewage tank. When the liquid level reaches the working water level from low to high Start the sewage pump, and when the liquid level reaches the low water level from high to low, turn off the working pump (the liquid level is detected by the liquid level switch). When starting the fan, check whether the direction of rotation is correct, and avoid reverse rotation. 4. The noise of the zero-discharge fan for livestock and poultry breeding wastewater is abnormal. Check whether the fan belt is too loose and whether to add lubricating oil in time. 5. When there is less sewage in the regulating tank and the liquid level is lower than the start level of the pump, the pump stops working. At this time, in order to allow the normal growth of the biofilm in the sewage equipment, the aerator is started intermittently. 6. When using zero discharge of livestock and poultry breeding wastewater, when there is abnormal sewage, it is necessary to check whether the connecting pipes of the oxidation tank, sedimentation tank, disinfection tank, and sludge tank are normal. These pools are cleaned to keep the water flowing. If the effluent water quality is not up to standard, then you need to check whether the water inflow is too large and adjust the valve. 7. The fan and water pump adopt automatic operation control. 8. The zero discharge control center of livestock and poultry breeding wastewater is completed in one time according to the design schedule on the electric control cabinet. (No manual control mode is allowed under special circumstances), manual control is through the key switch on the panel, and the submersible sewage pump, fan, etc. are manually controlled to turn on and off. Through the combination of various units in the zero discharge of livestock and poultry breeding wastewater, the equipment can achieve the effects of denitrification and phosphorus removal. For areas that need to adopt higher emission standards, or where water resources are scarce and need to be reused, the zero discharge of livestock and poultry farming wastewater can also meet the corresponding requirements.
