Abstract

The invention discloses a device for efficiently treating aged landfill leachate through a biological membrane and electric flocculation. The device comprises a shell, a cathode, an anode, suspended ball filler, a carrier and a magnet. According to the invention, electric flocculation, electric flotation and microbial degradation processes can be efficiently carried out at the same time, various pollutants difficult to treat can be effectively removed. The device has the advantages of simple operation, long-term operation and convenient maintenance, solves the problems of low utilization efficiency of sacrificial electrodes, larger space between polar plates, higher energy consumption, low ammonia nitrogen removal efficiency and the like in a double-electrode electrocoagulation method, simultaneously solves the problems of pollutants which are difficult to treat by microorganisms and biomembrane pollution in a biomembrane method, and is particularly suitable for treating old garbage percolate.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a device for efficiently treating old garbage leachate by biofilm and electrocoagulation. Background technique [0002] Electroflocculation technology is to produce aluminum hydroxide coagulant by electrolysis of aluminum anode through electrochemical process. By eliminating / neutralizing the repulsive force of particles in water, the particles are agglomerated into larger particles and settle down. At the same time, the cathode plate can generate tiny hydrogen bubbles , float the flocs with poor settling performance on the surface of the liquid. Electrocoagulation technology combines the advantages of coagulation, flotation and electrochemistry at the same time. It is clean and environmentally friendly. It is a water treatment technology with great potential. [0003] Electrocoagulation can be divided into single-electrode mode and double-electrode mode acco...
