Abstract

The invention provides a reactor, comprising a shell and a filtering device, wherein the shell is internally provided with an accommodating chamber for accommodating organic wastewater; the filteringdevice is arranged in the accommodating chamber and internally provided with a filtering chamber; the filtering chamber is communicated with the outside; and the filtering device is used for isolatingactivated sludge in the accommodating chamber from other parts. According to the invention, the activated sludge in the shell is constrained in the accommodating chamber by the filtering device, andinactivated sludge in the shell and filtered matters enter the filtering chamber and are guided out to an advanced treatment procedure; and the concentration of the activated sludge inside the accommodating chamber is ensured in virtue of the filtering device, so the reactor of the invention can continuously maintain a good state and has guaranteed long-lasting treatment capability.

Description

technical field [0001] The invention relates to the technical field of biochemical filtration, in particular to a reactor. Background technique [0002] At present, in the process of treating organic wastewater, it is often necessary to ensure that there is a relatively high concentration of activated sludge in the reactor in order to achieve the treatment effect. In order to prevent the loss of activated sludge, the following two methods are usually used. One is followed by sedimentation The pool is activated sludge backflow, and the second is to use the sequencing batch reactor to directly leave the activated sludge in the reactor. Other methods such as resin fiber filtration are rarely used due to high construction and operation costs. [0003] Settling tank and sequencing batch reactor still have some problems in application process, a kind of radial flow type secondary settling tank based on the vertical frame mud scraper announced as CN203899220U, though structurally d...
