Zusammenfassung: | The invention discloses a composite coagulant, disposing method and device of living effluent, which is characterized by the following: the composite coagulant is composite liquid of polysulfide aluminium chloride and polyacrylamide; the device contains composite reacting pond, sediment pond and five sucking ponds with different filtering materials; the supernatant in the sediment pond is adsorbed and filtered continuously by five sucking ponds through flocculating, sedimenting and adsorbing; the method makes phenolic hydroxyl group and some metal ion in the effluent to complex better, which shortens technical flow path and saves constructing cost with COD removing rate over 85% and ammonia nitrogen removing rate over 94%. |
