Problems solved by technology

However, the living habits of micro-animals are different from those of traditional water treatment microorganisms. It is difficult for traditional water treatment fillers to achieve high-density growth. At the same time, some existing micro-animal sludge reduction fillers are expensive and difficult to integrate Disadvantages such as realizing large-scale engineering applications on the

Abstract

The invention relates to a filler box device of microfauna sludge reduction. The device disclosed by the invention comprises a main body frame, supporting frames, box body fixing parts, top fixing grooves, vertical supporting fillers, flat plate supporting fillers, porous carriers, aerators, bottom fixing grooves and a box body peripheral outer shell. According to the filler box device of the microfauna sludge reduction disclosed by the invention, the internal structure adopts cheap PP materials, so that the production cost is low; the whole structure is compact and simple, so as to facilitate transportation and large-scale use of projects; furthermore, the filler box disclosed by the invention is high in filling ratio of internal fillers to provide a large amount of attachment area for the growth of microfauna so as to effectively improve the adhesion density of the microfauna and enhance the sludge reduction effect.

Description

technical field [0001] The invention belongs to the technical field of sludge biological reduction. In particular, it relates to a stuffing box device for miniature animal sludge reduction. Background technique [0002] With the popularization of urban sewage treatment in my country, the sludge produced by sewage plants is increasing day by day. By 2015, my country's sludge production will be close to 40 million tons (water content 80%). Due to the large output of sewage sludge, complex composition, and a large number of toxic and harmful substances such as pathogenic bacteria and heavy metals, the efficient treatment and disposal of sewage sludge is an urgent need to protect the health of our people and achieve sustainable environmental development. [0003] Micro-animal sludge reduction technology uses micro-animals such as worms to ingest and digest organic matter, activated sludge flocs, sludge fragments, and bacteria in the activated sludge mixture, which is the key to...
