Chinese medicine processing requires large amounts of water, due to the proprietary process, and the washing process, the plant will produce hyaluronic acid, and a lot of vegetable fibers. As the production process required to add a lot of sugar. Therefore, the water quality is better biodegradability, the cleaning process will bring out the parts of the plant residues. Water has a high COD, high suspended solids suitable for biochemical characteristics.
Sewage collected through a pipe into the ditch mechanical grid, which is mounted within the automatic rotary mechanical grille, the use of mechanical removal of larger grid to the water floating debris, debris, to prevent clogging follow-lift pump and piping. However, since the combined flow into the sump using wells installed a wastewater lift pump upgrade into the dissolved air flotation machine to suspended solids in water processing, reduce the technical difficulty and the subsequent biological treatment of organic load. The supernatant from the pool flows into the oxygen releasing reduce the dissolved oxygen content. Then enter the pool acid hydrolysis, water molecules group after hydrolysis acidification decomposed substance, is preparing to enter the EGSB pool, use of treated wastewater pretreatment secondary lift pump lift into the water distribution, waste water to form swirling water distribution evenly distributed into the anaerobic tank, anaerobic microbial decomposition of organic pollutants into the majority of methane, carbon dioxide and other gases. To reduce the subsequent aerobic treatment process and difficult to treat organic load, in order to ensure the biological treatment effect and operating cost savings, in the anaerobic treatment areas, designed with a lower load is high, a shorter residence time will maximize the removal of organic matter, so tired COD effluent oxygen at a relatively low level.
Anaerobic effluent from flowing into the biological contact oxidation pond, waste water oxygenation after a certain flow rate flowing through the filler, the activated sludge and biofilm together suspended the oxidative decomposition of organic matter in wastewater, water from flowing into the secondary sedimentation tank. Secondary settling tank multi-bucket advection sedimentation tanks, sludge settling down using submersible sewage pump discharge, a portion back to the inlet end of the aerobic system to supplement the amount of microbial oxidation pond loss, another part of the remaining sludge to row sludge thickening pool of gravity concentration. Secondary sedimentation tank effluent discharge standards. If the use of standards to improve the follow-up BAF effluent standards will be raised to an A standard.
Sewage sludge generated by the system (including the advection of primary sludge, anaerobic sludge, secondary sedimentation tank sludge) into the sludge thickener, concentrated by gravity into the frame using the sludge pump lifting machine dehydration, the dry mud after dehydration Sinotrans landfill disposal.
