Sewage purification device applied to eutrophic river estuary

Abstract

The invention belongs to the technical field of sewage treatment, and discloses a sewage purification device applied to the eutrophic river estuary. The device includes a floating bed frame and a power mechanism. An aerator and an air guide pipe connected with the aerator are arranged on the floating bed frame. The inner side of the floating bed frame is connected with a plurality of parallel PVCpipes. The PVC pipes are connected with the air guide pipe, aquaculture grids are arranged between the PVC pipes at intervals, and the salt-tolerant plants are planted on the aquaculture grids. Aeration pipes are arranged on the lower portions of the aquaculture grids at intervals, one end of each aeration pipe is communicated with the corresponding PVC pipe, and a counterweight ball is tied to the other end of the each aeration pipe; four corners of the floating bed frame are provided with support columns, the support columns are connected with ropes, and the free ends of the ropes are fixedon the river bank. The eutrophication problem of a water body of the river estuary is mainly solved by the bioremediation and aeration technology, the device is simple in structure, light and good inanti-corrosion performance, a frame body can change along with the fluctuation of tide and rotate and move by itself, solar energy and rainwater are used for generating electricity, and energy conservation and environment protection are achieve.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage purification device applied to eutrophic river estuaries. Background technique [0002] Eutrophication refers to the large amount of nutrients such as nitrogen and phosphorus required by organisms entering slow-flowing water bodies such as lakes, estuaries, and bays, causing algae and other plankton to multiply rapidly, the dissolved oxygen in the water body decreases, and fish and other organisms die in large numbers. Phenomenon. [0003] Water eutrophication is a global water environment problem. In China, more than 90% of its water pollution is caused by eutrophication caused by excessively high N and P contents in the water. N and P are the most important for plant growth. Basic essential nutrients. The ecological floating island technology uses floating materials as the substrate or carrier to plant higher aquatic plants or terrestrial plants in eutrophic...
