Integrated wastewater treatment device and using method thereof

Abstract

The invention discloses an integrated wastewater treatment device and a using method thereof and belongs to the technical field of wastewater treatment. The integrated wastewater treatment device comprises a first pipe body, a second pipe body and a third pipe body, wherein a wastewater inlet hole is formed in one side of the first pipe body, and a wastewater outlet hole is formed in one side of the third pipe body. A biological cathode is arranged in the first pipe body, and the surface of the biological cathode is provided with anaerobes. A filler and a micro-aerobic aerator are arranged in the second pipe body. A biological anode is arranged in the third pipe body, and the surface of the biological anode is provided with anaerobes. The using method of the integrated wastewater treatment device comprises the following steps that wastewater flows into the first pipe body, macromolecular organic compounds produce chemical bond breakage and are decomposed into micro-molecular substances; the wastewater flows into the second pipe body, and the micro-molecular substances are decomposed into easily degradable organic substances; the wastewater flows into the third pipe body, the easily degradable organic substances are decomposed by the anaerobes; the wastewater flows out of the wastewater outlet hole. The integrated wastewater treatment device is small in occupied area and can reduce the COD content in the wastewater without secondary treatment.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to an integrated waste water treatment device and a using method thereof. Background technique [0002] Wastewater treatment has always been one of the key issues in the field of pollution control, among which the treatment of industrial wastewater is the most important. The current wastewater treatment method is mainly based on anaerobic process, but due to the need for subsequent treatment, the treatment speed is relatively slow. As a new technology, microbial electrolysis cell can use its cathode reduction effect to reduce and break the chemical bonds of macromolecular organic matter in wastewater, degrading them into small molecules, but the wastewater treated by this method cannot be completely mineralized. Oxygen demand (COD) is high, and further mineralization treatment is required. The contact oxidation method can easily mineralize the wastewater a...

[0002] Wastewater treatment has always been one of the key issues in the field of pollution control, among which the treatment of industrial wastewater is the most important. The current wastewater treatment method is mainly based on anaerobic process, but due to the need for subsequent treatment, the treatment speed is relatively slow

As a new technology, microbial electrolysis cell can use its cathode reduction effect to reduce and break the chemical bonds of macromolecular organic matter in wastewater, degrading them into small molecules, but the wastewater treated by this method cannot be completely mineralized. Oxygen demand (COD) is high, and further mineralization treatment is required

The contact oxidation method can easily mineralize the wastewater and reduce the COD in the wastewater, but there are also disadvantages such as large equipment footprint
