Abstract
The utility model relates to an MBR (membrane biological reactor) sewage treatment device. The MBR sewage treatment device consists of a regulating tank, a biological contact reaction tank and an MBR tank, wherein a sludge separator is arranged above the MBR tank; a sludge pump arranged on the bottom of the MBR tank is connected with a water inlet tube of the sludge separator by a pipeline; an MBR membrane assembly and combined filler are arranged in the MBR tank; and the combined filler is arranged at the water inlet end of the MBR tank. According to the utility model, the biological contact reaction tank is adopted and combined filler is arranged in the MBR tank, so that activities of a biological bacterial colony are improved; a treatment process of combining an active sludge method with a membrane method strengthens bearing impact load of the system, so that the biological bacterial colony is more stable; process flow of sewage treatment can be shortened, and structure of the device is simple; the sludge separator is arranged to reduce conventional sludge reflux and reduce aeration rate; and a secondary settling tank is not needed, and floor space is a little.
Description
Technical field
The utility model relates to a kind of MBR waste disposal plant.
Background technology
More existing sewage disposal devices, not only complex process, long processing period, inconvenient operation, needs second pond, and facility floor space is large, and construction and running cost are high, are unfavorable for popularizing, and be not suitable for small-scale sewage treatment facility, and energy consumption are high.In recent years, also developed some integrated processing techniques, this integrated apparatus is generally embedded in underground, is difficult to keep in repair, once Controlling System is out of joint, whole sewage treatment facility will be paralysed, thereby causes water quality not up to standard.Many weak points such as sewage disposal technology basic forming, exists reactor many at present, and step is many, and reactor useful volume is little, and efficiency is low, be awkward.
Utility model content
The purpose of this utility model is to provide a kind of MBR waste disposal plant, the treatment process that activated sludge process is combined with embrane method, and this is the sewage disposal biochemical reaction cell system that a kind of reactor is few, step is few, efficiency is high.
The utility model is achieved through the following technical solutions: a kind of MBR waste disposal plant, is made up of the equalizing tank connecting successively, biological contact reaction pond and MBR pond; Top, described MBR pond is provided with sludge extractor, and the sludge pump that bottom, MBR pond arranges is connected with the water inlet pipe of sludge extractor by pipeline; Described MBR is provided with MBR membrane module and combined stuffing in pond, and combined stuffing is positioned at the feed-water end in MBR pond.
The bottom of described equalizing tank is provided with lift pump, and lift pump is connected with water distributor by water inlet pipe.
Further, the bottom in described MBR pond is provided with aeration tube, and aeration tube is connected with gas blower by pipeline.
The beneficial effects of the utility model: in employing biological contact reaction pond and MBR pond, combined stuffing is set and has improved biological bacterium colony activity, the treatment process that activated sludge process is combined with embrane method, has strengthened system anti impulsion load, makes biological bacterium colony more stable; Can shorten the technical process of sewage disposal, simple in structure; Sludge extractor is set to be reduced traditional sludge backflow, has reduced aeration rate; Without second pond, take up an area few.
