Treatment equipment and treatment method for domestic sewage

Abstract

The invention discloses treatment equipment for domestic sewage. The treatment equipment comprises a micro-aerobic biological bin, a denitrification bin, an anoxic biological bin and a biomass bin which sequentially communicate with each other; adjacent bin bodies communicate with each other through an inverted U-shaped pipe; planting cover plates cover the top surfaces of the micro-aerobic biological bin and the anoxic biological bin; a denitrification adjusting plate covers the top surface of the denitrification bin; the top surface of the biomass bin penetrates through a discharging pipe orifice; biological pipes are downwards suspended in the micro-aerobic biological bin and the anoxic biological bin through the planting cover plates on the top surfaces, the inner bottom of the denitrification bin is filled with denitrification filler, and the inner bottom of the biomass bin is filled with suspended filler; and biological pipes of the micro-aerobic biological bin and the anoxic biological bin are respectively filled with first biological filler and second biological filler through net bags. According to the invention, step-by-step catalytic decomposition and biochemical decomposition of domestic sewage are realized, and timely replacement of the biological filler and timely maintenance of the biological pipes are facilitated; effluent quality is ensured; and meanwhile, wastewater recycling effect is also realized.

Description

technical field [0001] The invention relates to domestic sewage treatment, in particular to a domestic sewage treatment equipment and a treatment method thereof. Background technique [0002] At present, there are many treatment technologies for domestic sewage. The commonly used treatment methods include advanced oxidation method, physical and chemical method, biological method (including biochemical method and ecological method), among which advanced oxidation method generally includes Fenton oxidation, ozone catalytic oxidation, physical field Collaborative advanced oxidation and other technologies, physical and chemical methods generally include coagulation, magnetic separation, activated carbon adsorption and other technologies, biochemical methods generally include anaerobic, facultative and aerobic treatment technologies, and ecological methods mostly use wetlands and plants for treatment. The above technologies have their own advantages, and are applicable to the tre...

AI Technical Summary

Problems solved by technology

[0003] The biological method in the existing domestic sewage treatment process often uses biological tubes filled with biological fillers to catalyze it. However, during the treatment process of the current biological tubes, the replacement of the biological fillers and the maintenance caused by the long-term use of the biological tubes, disassembly have a great impact on the treatment process. It caused a lot of inconvenience; and in the prior art, most of the treatment technologies for domestic sewage are not continuous, and the treatment methods do not form a systematic treatment process
