Aquaculture farming sewage effluent with a typical "three high" that is characterized by a high concentration of organic matter COD up 3000-12000mg / l, ammonia up 800-2200mg / l, suspended solids SS exceeded the number of times; high phosphorus content, biodegradability general ; big stink; flushing discharge time to focus on the impact of a large load.
Wastewater from farms into the first set of wells accumulated water, then upgrade to solid-liquid separator pump for separation. Setting solid-liquid separator purpose is to remove waste water manure-like substance, and avoid any further digesters, biogas digesters causing blockage, leading to clean up the difficulties and consequences can not be used. Carried out before entering the biogas manure solid-liquid separation measures can solve the sedimentation problem in cow dung digesters, biogas greatly enhanced processing power, but also greatly reduce the digester, biochemical pool construction area. Saving environmental treatment of capital investment and land use area, isolated from cow dung can also be used directly as fruit trees, forest fertilization and as an organic fertilizer raw materials.
Solid-liquid separator separated wastewater into the sedimentation tank, precipitation wastewater fine suspended particles separated precipitate regularly into collection basins, sewage goes adjust acidification tank.
Objective System Configuration regulating acidification tank of one regulation of water, wastewater and second, pre-acidification, improve the efficiency of the anaerobic unit.
Wastewater into the anaerobic reactor UASB reactor, a large number of wastewater removal of COD, BOD, will be converted into biogas. UASB reactor effluent into the flocculation tank, biogas is produced through the water sealing, through sealing desulfurization tank and water into the gas tank storage. Biogas power generation, wastewater treatment systems supplying electricity through biogas generators.
Wastewater PH adjustment tank lime dosing, adjusted PH conditioning, gravity into the sedimentation tank Ⅱ precipitation separation, sludge is discharged into collection basins.
After the anaerobic treatment of sewage through nitrification and denitrification, after distributing reservoir of accumulated waste water, pump lifting assigned to the aerobic tank.
Aerobic wastewater in the aerobic reaction, utilizing metabolism of aerobic microorganisms in the pool will be a large number of organic pollutants and ammonia nitrogen removal, so that the waste water has been purified. Sludge is discharged into collection basins.
Sludge treatment: solid-liquid separator to produce a dry sludge stored in a dry mud field; after collection basins, sludge pump sludge thickening tank upgrade to preliminary dewatering in filter presses fed dehydrated, isolated transport of dry mud to dry mud field.
