Electrical biological treatment apparatus for organic sewage

Abstract

The invention relates to an organic sewage electrobiological treatment device, which comprises a shell, wherein the inside of the shell is provided with a space for forming a water channel. The inside of the space for forming the water channel is provided with a biological filter material. The device is characterized in that the inside of the shell is also provided with a plurality of pairs of electrodes which extend in a direction perpendicular to the direction in which the water channel extends. The space in the shell is divided by up and down two water distribution plates into an outlet chamber, a reaction chamber and an intake chamber sequentially. The outlet chamber at the upper part is provided with an outlet pipe. The bottom of the intake chamber at the lower part is provided with an aerator. The inside of the reaction chamber in the middle contains the biological filter material. The biological filter material is packed or suspended in the reaction chamber. The positive and negative electrodes are inserted in the biological filter. The device can combine an electrolysis treatment process and a biological treatment process, gives play to the oxidation and reduction of electrolysis, improves the environment of biological treatment and the overall treatment capacity and effect and is mainly used for treating organic sewage, in particular organic sewage difficult to degrade.

Description

field of invention

[0001] The invention relates to a waste water treatment device, in particular to an aerobic biological treatment equipment under the action of electric current. Background technique

[0002] The existing organic sewage treatment is usually treated by biological treatment methods, including anaerobic biological method, aerobic biological method and anoxic biological method under anoxic state. For comprehensive treatment systems, especially for high-concentration organic sewage, Usually, anaerobic biological method is used to degrade complex organic substances into simple organic substances, and then decompose them into carbon dioxide and water through aerobic biology. However, with the development of industry, more and more Advanced fine chemical products are constantly coming out. In these products, many substances will not only seriously pollute the environment, but also are difficult to be biodegraded, such as chlorophenol, chlorobenzene, nitrobenzene, d...
