Buried sewage treatment equipment, sewage disposal plant is a modular, is a kind of biological treatment system of sewage purification bodies in biofilm, give full play to the anaerobic biological filter and contact oxidation bed biofilm reactor has the biological density, anti pollution ability, low power consumption, operation stable operation, easy maintenance, the system has a wide application prospect and popularization value. Here we introduce the buried sewage treatment equipment operation process:

First, the installation and commissioning personnel should first open the inlet valve, outlet valve, start equipment, water lifting pump, will adjust the pool (civil construction) of the sewage transported to the ground sewage treatment equipment began.

Two, for the first time to use and commissioning of sewage treatment equipment, when the pump stop the water level reached 1/2 height, open the blower inlet valve, open the blower fan, slowly open the valve to 48 hours aeration contact oxidation pool and start the water pump will be added to the sewage lifting equipment 3/4, and then to 24 hours aeration pool;

Three, the staff should touch the packing is a sticky feeling, at the same time to observe the growth of microorganisms in water, until the packing growth of a layer of orange biofilm, can continuous conveying equipment to sewage, water should be gradually increased to design water;

Four, regular observation of microbial growth in water, found abnormal, should be timely control of water intake to be adjusted;

Five, to observe the two sedimentation tank effluent weir flow, water must be uniform, generally every 24 hours must be a mud mud mud, open solenoid valve, the gas stripping way the two clarifier sludge to sludge pool;

Six, buried sewage treatment equipment, as required, in the disinfection tank to add disinfectant (chlorine, wafers, etc.), two sink water through the disinfectant tank, the pharmaceutical part dissolved, to achieve the purpose of disinfection. When the treated water stays in the water tank for about 0.5 hours, it meets the emission requirements and can be discharged to the outside world by water;

Seven, after the device debugging is finished and normal operation, the system can enter the automatic operation. The switch operation of pump and fan in the automatic mode, the electrical operation control cabinet is the use of PLC automatic control program, the equipment factory has been to the program (usually each class switch once, when running) need not set;
