Ecological treatment circulatory system for discharge water of sea farming pond

Abstract

The invention relates to an ecological treatment circulatory system for discharge water of a sea farming pond. The ecological treatment circulatory system is characterized by comprising an ecological water diversion ditch, wherein the beginning end of the ecological water diversion ditch is communicated with water in an offshore sea area; seawater is introduced through ebb and flow; a gate is also arranged, and the tail end of the gate is communicated with the beginning end of an ecological gravel bed through an overflow pipe; the tail end of the ecological gravel bed is communicated with the beginning end of a pre-positioned reservoir through an overflow pipe, and the tail end of the pre-positioned reservoir is communicated with the beginning end of a sea farming pond through an overflow pipe; the lower part of the tail end of the sea farming pond is communicated with the upper part of the beginning end of the ecological water diversion ditch through a water drainage pipe, and a water pump is arranged to provide drainage power; gravels with different particle sizes are arranged from the bottom up from the big to the small on the ecological gravel bed, and water plants are planted at the top; the pre-positioned reservoir is divided into a deep water area, an ecological floating bed area and a water source area from the beginning end to the tail end, of which the water depths are gradually reduced, sunken plants are planted in the deep water area, and an ecological floating bed is arranged in the ecological floating bed area.

Description

technical field [0001] The invention relates to a marine aquaculture pond discharge water ecological treatment circulation system, which belongs to the technical field of water pollution ecological restoration. Background technique [0002] Mariculture is an industry with great development potential in my country's coastal economic development. It not only provides people with high-quality food protein, but also guides fishermen to change industries, solves coastal fishermen's production, life outlets, and maintains economic development and social stability in fishing areas. are all significant. In recent years, due to excessive pursuit of aquaculture production, in the process of seawater fish, shrimp and crab pond culture, the stocking amount of cultured objects has been unilaterally increased, and too much bait and various drugs have been put in. As a simple ecosystem, seawater culture ponds Its internal food chain causes inefficiency within the ecosystem, blockage of mat...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is that the existing seawater culture ponds have serious ecological pollution, and the physical methods such as dredging, sedimentation, and filtration or the chemical methods using chemical reagents have been used for a long time, although the processing speed is fast, the processing The cost is high, and secondary pollution is easy to occur; the existing ecological restoration technology is relatively single, and there is no complete ecological restoration plan for mariculture ponds. In addition to considering water purification, the ecological restoration of mariculture ponds also needs to consider cooperation The steps of introducing seawater and factors such as oxygen enrichment and pH of the water body
