Abstract

The invention discloses an integrated precipitating and mud collection backflow device, which comprises a reactor, wherein a reaction zone and a precipitating zone are arranged in the reactor, a funnel with a big opening downwards is arranged in the precipitating zone, gaps are respectively arranged between the lateral side of the funnel and the inner wall and between the bottom end of the funneland the inner wall, the top end of the funnel is connected with a water collection pipe, and the water collection pipe is communicated with the reaction zone after being connected with a pump. The integrated precipitating and mud collection backflow device enables waste water to be sufficiently contacted with mud, organics in waste water to be well degraded, short streams and channeling not to beapt to appear and processing efficiency to be improved.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection, chemical industry, etc., and in particular relates to an integrated settling mud collecting and returning device. Background technique [0002] In the process of sewage and wastewater treatment and related chemical unit operations, the sedimentation, sludge collection and reflux devices of the reactor are a relatively common process. The process of removing sludge or other substances in the reactor from water or wastewater is called solid-liquid separation process. The process of separating solid from liquid is solid-liquid separation, including sedimentation, filtration, membrane method, press filter, centrifuge separation and other methods. In water treatment there are methods such as gravity sedimentation, microfiltration, clarification and deep bed filtration. Solids are generally removed from wastewater by filtration or sedimentation. Separation methods used in sludge tr...
