Embodiment 1

[0018] The drawing shows a specific embodiment of the present invention. The embodiment includes the sewage in the high-level water tank 16 enters the dissolved air distribution chamber 13 through the sewage metering pump 10 through the sewage pipe 20, and at the same time, the water discharged from the upper end of the three-dimensional particle electrode layer 15 is passed through the backflow The pump 11 passes through the return pipe 17, and returns to the dissolved air water distribution chamber 13 according to the volume reflux ratio: 1:1. The dissolved air water distribution chamber 13 is provided with an aeration plate 8, which passes through the aeration pipe 21 and the air compressor 7. The backwash water inlet pipe 19 is connected with the backwash pump 9, and the three-dimensional electro-biological coupling pool is inflated through the air compressor 7 to provide sufficient oxygen for the microorganisms and the three-dimensional particle electrode. In the dissolved a...

Abstract

A three-dimensional 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 plastic perforated plate. The periphery of the three-dimensional particle electrode layer is connected to a main electrode anode, the middle of the three-dimensional particle electrode layer is connected to a main electrode cathode, and the part between the main electrodes is filled with catalytic particle electrodes. 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; (4) performing three-dimensional particle electrode oxidation; and (5) discharging purified water. By interaction of the physical filtering, the aerobic treatment, and the three-dimensional particle electrode oxidation, predetermined treating effects can be achieved and stable water quality of the discharged water.

Description

Technical field [0001] The invention belongs to the technical field of wastewater treatment, and particularly relates to a three-dimensional electro-biological coupling water purification system and a water purification method that can be used for sewage treatment. Background technique [0002] With the development of the global economy, people have paid more and more attention to the problem of water pollution. Water is the lifeblood of the survival and development of cities. Controlling water pollution and protecting water resources is not only a worldwide problem, but also a top priority that my country’s urban and rural areas generally face. With the economic growth and the development of urban construction in China, the increasing number of urban residents and the improvement of people's living standards have stimulated the demand for sewage treatment. [0003] The electro-biological coupling technology is to couple the electrochemical reaction and the microbial reaction in t...
