Surface water protection and remediation floating bioreactor and using method thereof

Abstract

The invention relates to a water protection and remediation technique, in particular to a surface water protection and remediation floating bioreactor. In a vertical tubular barrel (2), a porous material serves as a carrier for a biomembrane (4); the center of the upper part of the barrel (2) is communicated with a vertically upward water outlet pipe (1), a water inlet (6) is formed at the bottomof the barrel (2), and the water inlet (6) is connected with a submersible pump (5); and a plurality of buoys (3) are arranged on the outside of the barrel (2). The using method of the bioreactor comprises: allowing solution containing microbes to be absorbed on the surface of the porous material to form the biomembrane (4); continuously delivering water to the reactor by the submersible pump (5)and allowing the water to flow by the surface of the biomembrane (4) to purify the water; and the outlet end of the water outlet pipe (1) is designed to be in a spring or waterfall mode. In the invention, the water purification and remediation speed is high, and the water purification and remediation quality is high; the bioreactor can float on water surface and can move and float in a larger water area to perform water remediation, the pertinence of the bioreactor is high, the effect is desirable, the overall remediation speed is high, and the bioreactor can be designed with a landscape enjoying and water purification combined structure.

Description

technical field [0001] The invention relates to water body protection and restoration technology, in particular to a device and a method for purifying and repairing water bodies polluted by river courses, landscape waters and aquaculture waters. Background technique [0002] With the development of industrial and agricultural production, many surface waters show the phenomenon of eutrophication, which is mainly caused by the increase of nitrogen, phosphorus and other elements in the water. The untreated discharge of industrial wastewater, agricultural backwater and domestic sewage into natural water bodies is the main reason for the increase of nitrogen and phosphorus in water bodies. In addition, due to the continuous development and expansion of the aquaculture industry, this further aggravates the pollution of landscape waters. For example, the Taihu Lake Basin strictly restricts various cage cultures around Taihu Lake. However, this kind of aquaculture still exists in l...

Problems solved by technology

Usually, when using plants to restore water bodies, it belongs to in-situ restoration, but its purification and restoration speed is very slow. For already polluted water bodies, it seems that "far away water cannot solve near thirst", and its purification and restoration speed cannot keep up with the speed of pollution.

When using microbial methods, if it is repaired in situ, when repairing a large water area, the area covered is not enough, and when using the usual in-situ repair method, if it is fixed in one place, it will appear and ectopic fix the same problem
