Abstract

A novel electric-biology coupled water purification system and a water purification method are disclosed. A three-dimensional particle electrode layer of the water purification system is disposed above an adsorption-type biological filtering material layer. The three-dimensional particle electrode layer and the adsorption-type biological filtering material layer are connected through a stainless steel perforated plate electrode. The bottom of the adsorption-type biological filtering material layer and a gas-dissolving water distributing chamber are connected through a plastic perforated plate manner. The water distributing chamber is connected to an aeration device and a refluxing device. The water purification method includes steps of: (1) mixing raw water with gas and refluxing water in the gas-dissolving water distributing chamber; (2) physically filtering and intercepting; (3) performing aerobic biological treatment to remove organic matters and to denitrify; (4) performing advanced oxidation; and (5) discharging purified water. The water purification system couples the advanced catalytic oxidation and the aerobic treatment into one reactor. Stages in water treatment are synergetic. By interaction of the physical filtering, the aerobic treatment and the advanced oxidation, predetermined treating effects are achieved and the water quality of the discharged water is stable.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an electro-biological coupling pool water purification system and a water purification method which can be used for sewage treatment. Background technique [0002] The electro-biological coupling technology is to couple the electrochemical reaction and the microbial reaction in the same reactor, and give full play to their respective strengths to achieve the purpose of complementing and enhancing the treatment effect, so as to improve the removal efficiency of sewage and reduce equipment investment. Biological treatment and electrochemical treatment are two important methods used for pollution control, each with its own advantages and disadvantages. Electrobiological coupling technology can give full play to the advantages of both, and make up for or overcome the shortcomings of each other, so it has better treatment effect and wider application.
