Description

An anaerobic fermentation device for wastewater

Technical field

The utility model relates to wastewater treatment, in particular to an anaerobic fermentation device for wastewater.

Background technique

In sewage treatment, water quality characteristics of low carbon and high nitrogen and phosphorus are common. Due to the low organic content of wastewater, the conventional denitrification process cannot meet the demand for carbon sources in the anoxic denitrification stage, resulting in the denitrification process being blocked, which greatly affects the Nitrogen removal effect in sewage treatment plants.

In order to improve the efficiency of nitrogen and phosphorus removal, carbon sources are usually used in sewage treatment. The wastewater produced by winemaking is rich in carbon elements. The winery itself also has treatment needs for the wastewater produced by winemaking, so the wastewater produced by winemaking is used. The wastewater undergoes anaerobic fermentation treatment to convert the macromolecular carbon in the brewing wastewater into small molecule carbon substances. Finally, the brewing wastewater is put into other wastewaters as an "external carbon source", which not only treats the brewing wastewater, but also eliminates the need for other wastewaters. Purchasing carbon sources reduces treatment costs.

However, there is a large amount of granular residue remaining in the brewing wastewater, which is not conducive to fermentation and subsequent use as an "external carbon source". An anaerobic fermentation device suitable for brewing wastewater is proposed.
