Abstract

The invention discloses a high-salt sewage pretreatment system. A sewage inlet pipe, an air inlet pipe and a sludge discharge hopper are arranged at the bottom of a composite water tank; a sewage outlet pipe, a clear water inlet pipe, a clear water outlet pipe, a liquid medicine box and a medicine inlet pipe are arranged at the top of the composite pool; a positive electrode, an anode water inlet pipe and an anode water outlet pipe are arranged on the left side of the composite pool; a cathode, a cathode water inlet pipe and a cathode water outlet pipe are arranged on the right side of the composite pool; the anode chamber of the composite pool is separated from the desalting chamber through an anode partition plate, and the cathode chamber is separated from the desalting chamber through a cathode partition plate; a plurality of concentration chamber elements are arranged in the composite pool; the structure flow channel space is wide, the water inlet requirement is wide, functional modules are diversified, the pollution resistance is high, and the cleaning method is practical.

Description

technical field [0001] The invention relates to sewage treatment, in particular to a high-salt sewage pretreatment system. Background technique [0002] The treatment of high salinity organic sewage is one of the difficulties and hotspots in domestic and foreign research. The domestic and foreign research on high-salt sewage mainly includes physical and chemical methods and biological methods. The biological method shows a high organic matter removal rate in the treatment of sewage, but the treatment of high-salt sewage by the biological method usually requires a longer domestication period, and the higher the salinity in the sewage, the longer the time required to domesticate the sludge; in addition, microorganisms Very sensitive to changes in the environment, sudden changes in salinity often cause serious disturbance to the treatment system. Physicochemical methods mainly include electrochemical methods, ion exchange methods, membrane separation methods, evaporation meth...
