Physicochemical-biological-ecological coupled aquaculture wastewater circulation treatment system and process

Abstract

The invention discloses a physicochemical-biological-ecological coupled aquaculture wastewater circulation treatment system and process. The system comprises a physicochemical enhanced treatment system, a biological-ecological coupled treatment system, an ecological treatment system and an aquaculture area which are sequentially connected with each other to form a circulation loop, and further comprises an intelligent water quality on-line monitoring system and connecting pipelines used for connecting the systems and the area, wherein surpassing pipelines are respectively arranged between the water outlet of the aquaculture area and the water inlet of an ecological pond and between the water outlet of the aquaculture area and the water inlet of enhanced treatment equipment; a backflow pipeline is arranged between the water outlet of a subsurface wetland system in the biological-ecological coupled treatment system and the water inlet of the aquaculture area; the intelligent water quality on-line monitoring system monitors the quality of wastewater at a water outlet of the aquaculture area and regulates and controls water flow in each connecting pipeline, each surpassing pipeline and each backflow pipeline according to a set target water quality requirement. Thus, self-control optimization learning and selection of different water flow channel lines are realized.

Description

technical field [0001] The invention relates to the field of aquaculture wastewater treatment, in particular to a physicochemical-biological-ecological coupled aquaculture wastewater circulation treatment system and process. Background technique [0002] Aquaculture water has the characteristics of large water volume, fewer types of pollutants and small content changes, so most aquaculture wastewater is slightly polluted water, the pollution load is relatively low, and treatment is relatively easy, but some aquaculture is more sensitive to water quality requirements , requires a relatively mature and perfect treatment process, and strives for low consumption and high efficiency and realizes recycling. [0003] At present, aquaculture wastewater mainly includes physical (represented by mechanical filtration and foam separation), chemical (represented by chemical oxidation such as ozone, hydrogen peroxide, etc.), biological (represented by algae, microorganisms, etc.) technol...
