The medical wastewater is first treated with a coarse grid to remove coarse suspended solids that may block the pump unit and pipeline valves, and to ensure the normal operation of subsequent treatment facilities. The wastewater in the regulating tank is treated by a lift pump and pumped into the medical wastewater treatment device. Here, most of the organic pollutants, bacteria, viruses and other pollutants are removed, and the wastewater is purified. Through the intelligent dosing of ultraviolet light + sodium hypochlorite "After double disinfection, it finally meets the GB18466-2005 "Water Pollutant Discharge Standard for Medical Institutions". The wastewater from the equipment is collected and disinfected before being discharged into the atmosphere.
The integrated sewage treatment plant is based on MBR ceramic flat membrane as the core process, divided into pretreatment tank, MBR biochemical tank, sludge tank, clean water tank and equipment room; the pretreatment tank includes: fine grid filtration, anoxic biochemical treatment. Hypoxia is denitrification. Denitrifying bacteria use organic matter in sewage as a carbon source to reduce the large amount of N03-N and NO2-N brought in the return sludge of the membrane pond to N2 and release it into the air. The concentration of BOD5 continues to decrease, and NO3 -N concentration has also dropped significantly; aerobic MBR pool: the organic matter in the water is adsorbed and degraded by aerobic organisms to purify the water quality,
This equipment uses ceramic flat membrane ultrafiltration as the core process, integrating traditional flocculation, precipitation, sand filtration, disinfection and other processes into an integrated unit, which can not only effectively remove organic matter in the water source. The equipment uses ceramic flat membrane ultrafiltration as the core process. Integrating traditional flocculation, sedimentation, sand filtration, disinfection and other processes into an integrated unit, not only can effectively remove organic matter, ammonia nitrogen, suspended matter, "two insects", pathogenic microorganisms, bacteria, etc. in the water source, but also can efficiently remove water The newly emerging trace pollutants such as environmental hormones, residual antibiotics, residual pesticides, etc., have a removal rate of over 99%, providing safer, healthier, and high-quality drinking water.
With ceramic flat membrane ultrafiltration as the core process, the use of ceramic membrane surface nano-pore filtration technology, combined with the flocculation process to effectively intercept coal powder, suspended solids, grease, heavy metal ions, etc. contained in the mine water, and adopt a unique operation mode to reduce membrane pollution.
