On the size of 500m3 / d of a cattle slaughter house wastewater process design. According to the sewage raw data and "outdoor drainage design" (GB50014-2006), to finalize a "hydrolytic acidification and biological oxidation" combined technology program.
After the wastewater collection network administered through the artificial gravity grille, remove the meat small wastewater, and giblets objects into the grease traps by artificial grid regulation pool after pretreatment of filters to remove the oil slick, ox hair, and things such as chop suey remove by mechanical grab, grease regulation pool also regulate the amount of water, all of the water, then pumped to a sewage lifting drum fine grid, fine grid to remove part of the drum of solid suspended matter and gravity to the sewage gas floating pool, the pump before adding coagulant (PAC) to react in order to ensure flotation device can effectively remove water in the oil, scum, color, and some organic compounds (CODcr, BOD5), after the water gravity flotation Hydrolysis into the pool, then into the anaerobic treatment of biological contact oxidation pool reaction, in which most of the organic pollutants by biological oxidation, adsorption can be degraded by biological treatment tank into the settling tank from solid and liquid separation, supernatant sedimentation tank overflow to the middle of the pool for disinfection of pool + chlorine dioxide disinfection, the disinfection of effluent from the filter lift pump to enhance access to ceramic filters and fiber ball filter, the effluent discharge standards.
Sludge secondary settling pond sludge by gas stripping, in part to hydrolysis acidification tank sludge return, sludge sent to another part of the sludge pond for further processing.
Interception by the grid under the regular cleaning of debris, two sinks provide the pool of sludge pumped to the sludge by use of gas pool; by flotation scum also entered the sludge treatment, sludge from the sludge from the sludge pond snail rod pump pumping to the frame filter press into the mud cake and Sinotrans. Supernatant and the sludge pool backwash water, filter presses are back to adjust the pool.
