Abstract

The invention relates to a household garbage and sewage system and particularly relates to a household garbage and sewage system and a process therefor. The household garbage and sewage system comprises a raw water tank, a regulating tank, a multi-phase coupled electrochemical device, a reoxidation pool, a catalytic oxidation tank, a solid-liquid separation device, an advanced oxidation tank, a solid-liquid separation device II, a biological oxidation tank and a trickling filtration tower. The household garbage and sewage system has the advantages that most of adopted devices are common devices, the whole system is low in construction cost, meanwhile, improvement can be directly carried out on the basis of an old sewage treatment system, and sufficient catalytic oxidation flocculation is carried out on raw water during primary treatment by using a multi-phase coupled electrochemical technology carried out under the condition of acidity of the raw water; the energy consumption in the whole system is basically focused on the aspects of a water pump, air supply and electrolysis; from the whole system, it is observed that ratios of the water pump, air supply and electrolysis in the whole system are extremely low, the energy consumption is extremely low, the cost of treatment of per ton of water basically can reach about 0.2 yuan and the applicability of the system is greatly improved.
