Abstract

The invention provides a combined floating bed device by coupling microorganisms and microelectrolysis and a domestic sewage treatment method, and belongs to the technical field of ecological engineering. The combined floating bed device consists of an upper plant area, a middle substrate area and a lower biofilm carrier area, wherein the upper plant area adopts root-developed and cold-resistant aquatic plants with good effect of adsorbing organic matters in sewage; the middle substrate adopts ion and carbon filler and high-efficiency film-hanging biological ceramsite, the filler is porous inorganic filler with high mechanical strength, large specific surface area, good adsorption property and high film hanging speed, and the stable and high-activity biofilm can be formed at the surface of the filler, so as to treat the organic matter in water at high efficiency; the lower biofilm carrier adopts combined filler, and the combined filler can be easily hung with the film, and can be used for effectively cutting air bubbles, so as to improve the transfer rate and utilization rate of oxygen, and treat the organic matter in the water at high efficiency. The combined floating bed can complete the functions of physical adsorption, chemical oxidization-reduction, electrochemistry, flocculation-precipitation, and film biological treatment.

Description

technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a combined floating bed device coupled with microorganisms and micro-electrolysis and a method for treating domestic sewage. Background technique [0002] With the continuous advancement of my country's urban-rural integration process in recent years, rural living conditions and economic development have been greatly improved, but the treatment of scattered sewage also needs to be resolved urgently. Ecological floating bed restoration technology is widely used in the treatment of various polluted water bodies. It has the advantages of simple operation, low cost, high purification efficiency, good treatment effect and low environmental risk. , chemical action, and ecological restoration technology for sewage treatment. Contents of the invention [0003] Aiming at the obvious problems that the existing ecological floating bed has a poor and unsatisfactory treatmen...
