Problems solved by technology

[0005] In the process of realizing the present invention, the inventors found that: existing eutrophic water body treatment and phosphorus recovery technology has relatively large deficiencies, especially phosphorus recovery, which is limited to domestic sewage, industrial wastewater and sludge with high phosphorus concentration. Adsorption or crystallization processes are often used, which require the construction of supporting facilities and the consumption of reagent materials. The operating costs are high, and it is difficult to popularize and apply to the treatment of natural eutrophic water bodies.

Embodiment Construction

[0020] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0021] figure 1 Shown is a schematic structural view of the integrated device for solar eutrophication water treatment and phosphorus recovery of the present invention. The integrated device for solar eutrophication water treatment and phosphorus recovery includes a solar panel 21 and a buoy 1 connected thereto. The buoy 1 of the embodiment of the present invention is made of waterproof, anti-corrosion and anti-collision high-density polyethylene material, which is used to provide buoyancy for the whole device. The buoy 1 is equipped with a mud-water mixing zone 10, an anaerobic zone 2, anoxic zone 3, an aerobic zone 4, and a sludge settlement zone 15; a storage battery 20, a sewage pump 19, a sludge pump 7 and an air compressor 18 are also arranged .

[0022] An anaerobic zone 2 is provided in the mi...

Abstract

The invention relates to a solar eutrophicated water body treatment and phosphorus recovery integrated device which comprises a solar panel and a float bowl connected with the solar panel, wherein the float bowl is provided with a sewage pump, a sludge pump, a storage battery and an air compressor; the solar panel is connected with the storage battery; the sewage pump, sludge pump and air compressor are respectively connected with the storage battery; the middle part of the float bowl is provided with an anaerobic region; the bottom of the anaerobic region is communicated with a sludge settling region through a sludge-water mixing region; the upper part of the anaerobic region is communicated with an anoxic region on the periphery of the anaerobic region; the upper part and lower part of the anoxic region are respectively communicated with the aerobic region; a biological rope is respectively suspended in the anaerobic region and aerobic region; the bottom of the aerobic region is provided with a microporous aeration head connected with the air compressor; and both sides of the upper part of the float bowl are respectively provided with a drainage port communicated with the aerobic region. The device does not need to treat the water body after extracting the water body to the bank side, has the advantages of high fieldwork capacity, low operating cost, no investment into chemical agents and materials, and no generation of solid wastes, and is capable of removing organic matters and nitrogen in the water body and recovering phosphorus in the form of sludge.

Description

technical field [0001] The invention relates to the field of water resource protection and water environment treatment, in particular to an integrated device for solar eutrophication water treatment and phosphorus recovery. Background technique [0002] The degree and scope of eutrophication of lakes and reservoirs caused by excessive nutrients (mainly nitrogen and phosphorus) is developing rapidly in my country, and the situation is very severe. Taking lakes as an example, the proportions of eutrophication in the 1970s, 1980s and 1990s were 41%, 61% and 77% respectively. The lake water quality survey results from 2007 to 2010 showed that 85.4% of large shallow lakes in my country exceeded the eutrophication standard, and 40.1% of them were severe eutrophication. The eutrophication of lakes and reservoirs deteriorates water quality, induces a "water quality" water shortage crisis, reduces the comprehensive utilization efficiency of water resources and the ability to guarant...
