a waste water treatment system

Abstract

A wastewater treatment device, including a reactor and a DC power supply, the reactor is a double-layer tower structure, the inner tower is filled with iron filings to form an iron filings cathode, and the iron filings cathode is connected to the negative pole of the DC power supply; An aeration device is arranged at the bottom of the inner tower body to drive the waste water to flow upward; diversion holes are arranged on the side of the inner tower body to form the flow between the outer tower body and the inner tower body; the inner tower body is divided into upper half and the lower half, the diversion hole is arranged on the side of the upper half of the inner tower body, and the side of the lower half of the inner tower body is a closed side.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a device for treating organic waste water by the electric Fenton method. Background technique [0002] At present, the increasingly serious water pollution has plagued the development of economy and society, and has also become the main factor restricting the sustainable development of society and economy. At present, the problem of organic wastewater pollution in my country is becoming more and more serious, causing great harm to human, animal health and ecological environment. Especially the wastewater produced by the printing and dyeing industry has the characteristics of large water volume, toxicity and refractory biodegradation, and the traditional wastewater treatment method cannot achieve the ideal treatment effect. Therefore, as a green technology, advanced oxidation technology has been widely concerned because of its rapid and thorough response and no secondary pollution. Th...

However, 201110061257.4 also has the following disadvantages: on the one hand, as the reaction proceeds, the reduced organic matter will adhere to the surface of the cathode, affecting the reduction effect; while the concentration of organic matter in the wastewater decreases gradually as it is purified from bottom to top, so the system After running for a period of time, the reduction effect of the cathode in the inner tower becomes worse as the height decreases, resulting in the need to replace the entire cathode; The bottom of the tower flows to the outer tower through the diversion hole, and flows out from the water outlet, but does not fully pass through the cathode in the inner tower, resulting in poor treatment effect
