Sewage treatment device and sewage treatment method applying same

Abstract

The invention discloses a sewage treatment device and a sewage treatment method applying the same. The sewage treatment device comprises a sewage electrolytic treatment device, a residue receiving tank and a dehydration device; an electrode plate is arranged in the sewage electrolytic treatment device, a scum discharging device is fixedly arranged on the sewage electrolytic treatment device, the sewage electrolytic treatment device is communicated with the residue receiving tank or a coating chamber, the residue receiving tank is communicated with the dehydration device, and sewage in the residue receiving tank is conveyed into the dehydration device through a fourth tubing to be dehydrated. Therefore, the whole device is simple in structure and small in occupied area, no chemical is needed during operation, solid waste is reduced by 30-50%, and water is used circularly without emission. The water treated by the device forms ionized water which is low in viscidity, water pipe blocking is prevented, bacteria and mould in the water can be inhibited, and the deodorization effect is achieved. In addition, organic solvent (containing methylbenzene and dimethylbenzene) attached in the water can be electrolyzed into harmless benzoic acid, and VOCs organic volatilization is reduced. The device has the advantages of being high in environmental protection property and capable of recovering and using sewage.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device and a sewage treatment method using the same. Background technique [0002] The general sewage treatment methods basically use the coagulation precipitation method and redox method of drugs. In the final stage, biological treatment, activated carbon filtration treatment, ozone sterilization treatment and other methods are used, but no matter which method is used, expensive equipment costs, The cost of treatment and the area occupied will put a certain pressure on the enterprise, and the way of using drugs for treatment will also have a certain impact on the environment. Contents of the invention [0003] In order to solve one or more of the above, a sewage treatment device and a sewage treatment method using the same are provided. [0004] According to one aspect of the present invention, a sewage treatment device is provided, including a sewage electr...
