Description
Technical field
The utility model relates to biochemical treatment process a kind of general-purpose equipment used of trade effluent and municipal effluent, specifically relates to a kind of and microporous membrane the opened chip aerator matched use of gas distribution pipe.
Background technology
Biochemical process is the method for a kind of main employing in sewage disposal, and it utilizes the alternating action of aerobic bacteria, anoxic bacteria and anerobe except the various organic pollutants in decontaminated water.When carrying out aerobic treatment, must be filled with air in waste water with aerator.
One of purpose of existing sewage work upgrading project needs to solve the denitrogenation dephosphorizing problem.In the situation that effectively utilize existence conditions, can take intermittent aeration (sludge concentration 1000-20000mg/l) by building the denitrogenation dephosphorizing pond, and design therein the requirement that aerator combined with intelligent Controlling System reaches intensified denitrification and dephosphorization.
Microporous membrane chip aerator is the necessary key equipment in the similar sewage disposal technologies such as biochemical process, and the quality of its performance directly affects the success or failure of sewage treatment process, the height of overhead charges and the stability of operation etc.
Generally, the power consumption of aeration process accounts for 30% of sewage work's overhead charges, if improve the oxygen-transfer efficiency of aerator under different sludge concentrations, overhead charges will proportionally descend.Microporous membrane chip aerator consumption in engineering of water treatment is huge, and they are fixed on the huge aerating system of composition on gas distribution pipe.
China Patent No. 01245478.8 discloses a kind of microporous diaphragm aeration apparatus of opening, and this aerator profile is ball collar shape, and centre and top are stressed, the excessive stretching of the inhomogeneous easy generation part of diaphragm applied force.Long term operation in this case, the position attenuation that excessively stretches, loss resilience.And the micropore that can open micro-hole aerator is in-line, than being easier to, tear, in high sludge concentration, micropore easily stops up, and air velocity is fast, and bubble is large, and coefficient of oxygen utilization reduces.
The utility model content
Order of the present utility model is to overcome the deficiencies in the prior art, and a kind of microporous membrane chip aerator of opening is provided.
The technical solution of the utility model is summarized as follows:
A kind of microporous membrane chip aerator of opening, comprise that middle part is connected with the support tray 1 of air-supply duct, the lower surface of support tray 1 periphery is to being arranged with circular stiffening ring 8, be provided with stiffening plate 7 in the bottom of support tray 1, the middle part of support tray 1 is provided with bolt and nut 2, support tray 1 is connected with the flow deflector 3 with diversion trench by bolt and nut 2, be provided with ring-type preventing deformation groove 4 at the middle part of support tray 1 upper surface, aeration membrane 5 is flexibly connected by fixed ring 6 and the circular stiffening ring 8 of support tray 1, the thickness at the middle part of aeration membrane 5 is greater than the thickness of periphery, be provided with ㄚ type micropore 9 on aeration membrane 5, support tray 1 is the plane disc type.
Advantage of the present utility model:
Compact construction, gas distribution is even, and bubble is little, and coefficient of oxygen utilization is high, and energy consumption is low, the diaphragm indefatigability, under high sludge concentration, the diaphragm micropore is difficult for stopping up, impervious leakproof, long service life, aeration membrane and support tray are connected firmly.

Fig. 2 is vertical view of the present utility model.
Fig. 3 is ㄚ type microvoid structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of microporous membrane chip aerator of opening, comprise that middle part is connected with the support tray 1 of air-supply duct, the lower surface of support tray 1 periphery is to being arranged with circular stiffening ring 8, be provided with stiffening plate 7 in the bottom of support tray 1, the middle part of support tray 1 is provided with bolt and nut 2, support tray 1 is connected with the flow deflector 3 with diversion trench by bolt and nut 2, be provided with ring-type preventing deformation groove 4 at the middle part of support tray 1 upper surface, aeration membrane 5 is flexibly connected by fixed ring 6 and the circular stiffening ring 8 of support tray 1, the preferred terpolymer EP rubber of aeration membrane 5, the thickness at the middle part of aeration membrane 5 is greater than the thickness of periphery, be provided with ㄚ type micropore 9 on aeration membrane 5, support tray 1 is the plane disc type.
The ㄚ type micropore that aeration membrane arranges is difficult for stopping up under different mud concentration, and time intermittent aeration more than a day effectively prevents that excess impact from stretching during aeration simultaneously, has reduced diaphragm and has used tired.Extended its work-ing life.When quitting work, ㄚ type aeration membrane can be replied and is close on support tray, and ㄚ type micropore closes and prevents sewage backflow.
Through experiment, during the utility model oxygenation, bubble distribution is even, bubble diameter 0.9～1.9mm, and 0.3～0.5 square of service area is difficult for blockage of the micro orifice occurs in intermittent aeration and sludge concentration 1000-20000mg/l environment, and oxygen-transfer efficiency is high, can economize on electricity 25～30%.Be applicable to the environment of intermittent aeration and sludge concentration 1000-20000mg/l.
