Abstract

The invention relates to a sludge reduction and concentration integrated device which comprises a tank body, a fixed plate, a predator attachment plate and an attachment plate driving mechanism, the predator attachment plate is arranged in the pond body, micro organisms for preying sludge are inoculated in the predator attachment plate, the sludge flows into the pond body below the predator attachment plate through the predator attachment plate, and the attachment plate driving mechanism is arranged on the fixing plate and used for driving the predator attachment plate to ascend and descend between the interface of the sludge settled in the pond body and clear water. A sludge concentration tank and a sludge biological predation technology are combined to construct a sludge reduction and concentration integrated device, vermiliaceae worms are added into the integrated device and inhabit in sludge, the sludge concentration is reduced through biological predation, and sludge reduction is achieved; meanwhile, the inorganic biological disturbance behavior of the earthworm excrement is utilized, so that the sludge settling performance is improved, the sludge is easier to settle and concentrate, the sludge retention time is shortened, the sludge dewatering efficiency is improved, and the operation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated device for reducing and concentrating sludge. Background technique [0002] With the substantial increase in sewage treatment capacity and increasingly stringent discharge standards for effluent from sewage treatment plants, the output of excess sludge is also increasing. The research direction of excess sludge mainly includes: the treatment and disposal of excess sludge and the reduction of excess sludge output. People have turned their research direction from the research on the treatment and disposal technology of excess sludge to the research on the reduction of excess sludge output. In-situ sludge reduction (process reduction), which is essentially different from volume reduction (end reduction) that only reduces sludge volume by reducing the water content of sludge, reduces the generation of excess sludge from the source, It can effectiv...
