Sewage treatment system and method based on mriophyllum elatinoides biological oxidation pond

Abstract

The invention provides a sewage treatment system and method based on a mriophyllum elatinoides biological oxidation pond. The system comprises an anaerobic acidification regulation pool, an efficientmriophyllum elatinoides biological oxidation pond and a mriophyllum elatinoides aquatic organism pond which are sequentially communicated with each other, wherein the anaerobic acidification regulation pool serves as a sewage pretreatment stage and is used for equalizing the water quantity and quality; the efficient mriophyllum elatinoides biological oxidation pond serves as a secondary sewage treatment stage and is mainly used for removing organic pollutants, ammonia nitrogen and phosphorus; and the mriophyllum elatinoides aquatic organism pond serves as a tertiary sewage treatment stage, andis used for further removing organic pollutants, ammonia nitrogen and phosphorus and carrying out advanced sewage treatment and multistory cropping and breeding. The system and method provided by theinvention has the advantage that through the multi-stage treatment and reasonable configuration and sufficient utilization of animals and plants, the sewage treatment efficiency and quality can be improved.

Description

technical field [0001] The invention belongs to the field of agricultural non-point source pollution control and treatment, and in particular relates to a sewage treatment system and method based on a green foxtail algae biological oxidation pond. Background technique [0002] Rural domestic sewage or free-range livestock and poultry sewage usually contains a large amount of organic pollutants, as well as nitrogen, phosphorus and other elements, which cannot be directly reused, and need to be purified by certain purification technologies. At present, in the control and treatment of agricultural water pollution, the stabilization pond system is generally used to purify sewage. Commonly used stabilization ponds are divided into the following types: [0003] (1) Aerobic pond. Aerobic ponds decompose organic matter through aerobic bacteria, and the decomposed products are used by algae, and algae release oxygen through photosynthesis to be absorbed by aerobic bacteria to purif...
