The present disclosure relates to water environment governance technology, and particularly discloses an urban river/lake water environment multi-interface governance and restoration method. The method is a multi-interface coordinated governance and restoration method based on 'control for bottom, regulation for middle and governance for top', including: 'control for bottom'&#x2014;controlling the emission of sediment nutritive salts and the dormancy and recovery of algae; &#x201c;regulation for middle&#x201d;&#x2014;regulating primary productivity in a water body to inhibit the recovery of the algae; and &#x201c;governance for top&#x201d;&#x2014;reducing nitrogen and phosphorus nutrients of an air-water interface to control the reproduction and growth of the algae. In the present disclosure, the water body governance and restoration technology based on interface coordination can effectively inhibit the outbreak of cyanobacteria and avoid extreme conditions in the ecosystem.

Methods for water environment multi-interface governance and restoration in rivers and lakes

The present application relates to the technical field of water environment governance, and particularly discloses a method for accurate positioning and in-situ treatment of pollutants at a sediment-water interface. In the method, high-throughput sequencing technology and pollutant source apportionment technology are firstly used to perform accurate positioning on the sediment to be controlled, and then electrodialysis-vacuum negative pressure dewatering technology is used to perform in-situ dewatering treatment on the sediment to be controlled, thereby realizing accurate governance with the minimum desilting amount. In the present application, in further cooperation with the application of microbial reagents, the microbial flora environment of the sediment-water interface is regulated, thereby increasing the dewatering speed of the sediment.

Method for accurate positioning and in-situ treatment of pollutants at sediment-water interface

The present application provides a device for treating a black and odorous water body comprising a pre-treatment unit, a biomimetic intestine tubular purification system which imitates a digestion of small intestine, a microbial fuel cell which imitates a digestion of large intestine, and an inclined tube sedimentation tank which imitates human excretion.

Device for treating a black and odorous water body with a bionic process

The present application provides a method for treating a black and odorous water body comprising the following steps: pre-treating the black and odorous water body; passing the pre-treated water body through a biomimetic intestine tubular purification system which imitates a digestion of small intestine; passing the tubular purification system-treated water body into a microbial fuel cell which imitates a digestion of large intestine to treat the water body; and pumping the microbial fuel cell-treated water body into an upward flow inclined tube sedimentation tank to treat the water body.
