Further, be provided with in described MBR biochemical reaction tank for the sludge lifting pump in the sludge digestion tank with the sludge lifting in the pond.
4
,A kind of middle water treatment device according to claim 1 is characterized in that: also comprise for the aerating apparatus to anoxic pond and MBR biochemical reaction tank aeration.
Further, described aerating apparatus comprises blower fan, and is arranged on the aerated conduit at the bottom of anoxic pond and MBR biochemical reaction tank pond.
Further, be provided with the MBR membrane module in described MBR biochemical reaction tank.
Further, described MBR membrane module comprises hollow-fibre membrane, support, shrouding, aeration frame, suction outlet conduit, described middle control tunica fibrosa is located orifice plate by diaphragm and is fixed on support, described shrouding is arranged on the framework surrounding to form the filtering chamber of a sealing, described aeration frame is arranged on the bottom of described support, described pump up water pipeline is all along the support setting, and the pump up water pipeline is connected with suction pump.
Further, the aerated conduit at the bottom of described MBR biochemical reaction tank pond comprises the peripheral aerated conduit that is arranged on the pond bottom perimeter and is arranged on diaphragm aerating pipelines in the aeration frame of bottom of support of MBR membrane module.
The utlity model has following beneficial effect:
One, the aerating pipelines of the utility model MBR biochemical reaction tank is divided into two-way, and one the tunnel carries out aeration to peripheral active sludge, and aeration is carried out to the diaphragm of membrane module in another road.Its advantage pats diaphragm for the scouring force that produces by the diaphragm aeration to the MBR membrane module mutually, can shake off to be attached to like this calcification mud on fenestra surface, makes membrane flux greatly improve the work-ing life that has extended film, thereby has reduced running cost.
