Abstract

The invention discloses a sewage treatment system, which comprises an anaerobic trough, a sand leach trough and a communicating pipeline, wherein a water inlet and a drain outlet are arranged on the anaerobic trough, the inside of the anaerobic trough comprises a padding and special compound probiotics which are fixed and reserved on the padding, the sand leach trough is connected with the anaerobic trough through the communicating pipeline and used for filtering sewage passing through the anaerobic trough again; and the sand leach trough further comprises a water outlet, a drain outlet and a backwashing drain outlet, wherein the water outlet discharges the sewage filtered through the anaerobic trough and the sand leach trough, and the filtered sewage is same with clear water in vision and smell, and can be repeatedly recycled.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a sewage treatment system capable of removing organic matter and suspended solids in sludge and waste water. Very simple. Background technique [0002] Therefore, the current urban domestic sewage treatment methods include physical methods, chemical methods and biological methods, mainly including activated carbon adsorption, chemical precipitation, density separation, chemical oxidation, chemical reduction, ion exchange, membrane dialysis, gas and wet oxidation methods, etc. method. When the COD is 2000-4000mg / L, the COD removal rate of physical and chemical methods can reach 50%-87%. Therefore, compared with biological treatment, physical and chemical treatment methods are not affected by changes in water quality and quantity. However, the cost of physical and chemical methods is relatively high, and they are not suitable for the treatment of large volumes of domestic sewage. ...
