Abstract

The present invention relates to a sewage treatment combined wet land system and its sewage treatment process. Said sewage treatment combined wet land system includes biological regulation pool, aerobic degradation and microbial culture pool, artificial underflow wet land unit and artificial surface flow wet land unit, and its sewage treatment process includes the measures of natural precipitation, biological absorption, degradation and conversion, aeration reaction and others so as to make the sewage obtain purification treatment.

Description

technical field [0001] The invention relates to a sewage treatment system and a treatment process thereof, in particular to a domestic sewage treatment system with artificial wetland as the main body and a treatment process thereof. Background technique [0002] There are various existing sewage treatment systems and methods, mainly including chemical methods, biological methods and biochemical methods and the sewage treatment systems constructed by these methods. Among them, the use of biological methods to construct sewage treatment systems for point source treatment according to local conditions has become a development trend. According to document retrieval, do not find the same or similar point source sewage treatment system and sewage treatment process thereof of the present invention temporarily, but have found the method and the device that utilize artificial wetland treatment sewage alone, as WISCO Mining Company Daye Iron Mine discloses " The patent application fo...
