Ecological restoration transformation method for urban inland river sewage and sludge
InactiveCN106746403ASmall amount of workReduce water flowGas treatmentSludge treatmentMunicipal sewageDitch
The invention discloses an ecological restoration transformation method for urban inland river sewage and sludge. The method is started from three aspects as follows: (1) sewage in a to-be-treated polluted inland river is drained and the sludge at the bottom of the river is eliminated until a pebble bed is exposed; (2) an annular sewage treatment ditch is dug in the periphery of the inland river, the digging depth is to expose the pebble bed and the municipal sewage enters the sewage treatment ditch; and (3) eliminated sludge is stacked at two sides of the sewage treatment ditch to form a dam of the sewage treatment ditch. The transformation method belongs to pure natural and pollution-free original ecological restoration method and the influences of pollution and the like on surroundings are avoided. Compared with an existing transformation method, time and labor are saved and the cost is reduced.

The invention discloses a high-efficiency oxygen charging ecological treatment system. The high-efficiency oxygen charging ecological treatment system comprises a floating wetland and auxiliary facilities; the auxiliary facilities comprise a solar energy power supply system, a nanometer aeration system, bionic waterweed, and a landscape lighting system; the solar energy power supply system used for energy supply is arranged above the floating wetland; the nanometer aeration system, and the landscape lighting system with requirements on power supplies are arranged on a platform of the floatingwetland; a water inlet and a water outlet of the nanometer aeration system, and the bionic waterweed are arranged below the platform of the floating wetland. The high-efficiency oxygen charging ecological treatment system can be used for removing toxic and eutrophication matters such as organic matters, phosphor, ammonia, and nitrites in water bodies effectively; purification activation, dark color changing, and deodorization of water bodies can be realized based on water body area, depth, and contamination degree through flexible combination of the size and number of the floating wetland, andwater body ecological restoration and water quality improving are realized.
