Aquaculture water-break bypass treatment and ecological repairing circulation treatment method

Abstract

The invention discloses an aquaculture water-break bypass treatment and ecological repairing circulation treatment method. A system comprises an aeration oxidation pond, artificial floating islands, aflocculation precipitation pond, a multi-stage surface flow and subsurface wetland which are sequentially connected. By using a pretreatment technique of the aeration oxidation pond and the flocculation precipitation pond, pollutants and total phosphorus in wastewater can be efficiently removed; due to adoption of plants, benthonic animals and microorganisms in the multi-stage surface flow and subsurface wetland, the water environment and the water transparency can be remarkably improved, and a water body can be earth surface type-V water. A purified water body is circulated in the wetland toform a landscape water body. When water is taken from an aquaculture pond as seasonal water, the water is recycled into the aquaculture pond, then aquaculture recycling and reuse can be achieved, a circulation ecological breeding system in the pond can be formed, and the city water body environment can be improved; in case of ecological water shortage, the water can be used as a city sponge waterbody which is returned to rivers.

Description

technical field [0001] The invention belongs to the technical fields of aquaculture technology and wetland ecological restoration. The invention relates to a system and method for aquaculture return water bypass treatment and wetland ecological restoration cycle treatment. Background technique [0002] In recent years, intensive aquaculture has developed rapidly at home and abroad, especially in my country. Its aquaculture production has accounted for about 2 / 3 of the world's aquaculture production. The high-efficiency open farming adopts the method of large introduction and large row, which greatly consumes water resources. Due to the application of feed, the use of fungicides and disinfectants, the discharged water contains a large amount of granular and dissolved waste high in nitrogen and phosphorus, and antibiotic wastewater causes nitrogen and phosphorus in rivers, lakes and other waters to exceed the standard, which is likely to cause eutrophication of surrounding wat...

AI Technical Summary

Problems solved by technology

Although the integrated equipment is specially used for the treatment of aquaculture return water, the effect is good, but the aquaculture return water is only drained for 4 months in a year, and the equipment is idle for the remaining 8 months, and a large amount of manpower and material resources are required to be reinvested in each operation. system

Secondly, individual aquaculture is recycled by setting up multi-stage filtration, sedimentation, and submerged plant mixing. Although these methods are effective, most farmers have limited aquaculture areas, and it is impossible to set up a set of mixed aquaculture ponds. Multi-stage water treatment equipment
