(1) processing efficiency is high, and water outlet can direct reuse.Because this device adopts hollow-fibre membrane (MBR) mixed solution to biochemical reactor to have efficient centrifugation, thoroughly mud can be separated with water outlet, therefore the SS of water outlet and turbidity can be made close to zero, simultaneously because the loss of active sludge is almost nil, make the comparable traditional technology of the activated sludge concentration in biochemical reactor exceed 2-6 doubly left and right, substantially increase denitrification ability;
(2) system run all right, flow process is simple, equipment is few, floor space is little.Because the activated sludge concentration of MBR technology is high, therefore the volumetric loading of device is large; Good, stable to the shock resistance of water inlet fluctuation.This technique, except greatly reducing the volume of biochemical reactor-aeration tank, makes, beyond equipment and structures miniaturization, even can save preliminary sedimentation tank, also not need second pond and filtering system, just makes system footprint area reduce.
(3) sludge age is long, and surplus sludge volume is few.When sludge concentration is high, and when influent load is low, system Middle nutrition and microorganism ratio (F/M) low, sludge age is elongated.When F/M maintains certain low value, the growth of active sludge is close to zero, and this reduces the processing costs to excess sludge.
(4) convenient operation and management, is easy to realize automatic control.Because membrane sepn can make active sludge be trapped in completely in bio-reactor, make the hydraulic detention time in bio-reactor (HRT) and sludge retention time (SRT) be distinct, therefore can be controlled flexibly, stably; Meanwhile, be highly susceptible to realizing automatic control, improve the automatization level of sewage disposal.
Above-described is only preferred embodiments of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the principles of the present invention, can also make some improvement and modification, this is also considered as protection scope of the present invention.
