Abstract

The invention discloses an annular plug-flow micro-animal biological bed and a method for treating sewage sludge by using the same, which relates to a micro-animal biological bed and a method for treating sewage sludge by using the same. The purpose of the present invention is to solve the disadvantages that the existing device has poor sludge reduction effect and cannot be coupled with a circular water treatment process efficiently and integrally when treating sewage. An annular plug-flow micro-animal biological bed includes a mud inlet device, a mud discharge device, a filler, a plug-flow device and a perforated wall; The animal biological bed; the filler is uniformly arranged inside the micro animal biological bed; the push flow device is evenly arranged inside the micro animal biological bed; a perforated wall is arranged between the two stages of the micro animal biological bed. The device of the invention is suitable for treating sewage sludge.

Description

technical field [0001] The invention relates to a micro-animal biological bed and a method for using it to treat sewage sludge. Background technique [0002] The activated sludge method is mostly used in the treatment of urban wastewater in our country. It has the advantages of strong impact resistance, ability to degrade organic matter, and good treatment effect. However, this method will produce a large amount of excess sludge during operation. The remaining sludge is rich in harmful substances such as organic matter, heavy metals, and pathogenic microorganisms. Improper treatment will lead to serious environmental problems. [0003] Sludge process reduction technology is a technology that develops a sludge treatment unit that is effectively coupled with the sewage treatment process, and realizes the reduction of sludge production in the process of sewage treatment. Compared with traditional terminal treatment technologies such as landfill and incineration, this technolog...
