Description
Technical field
The utility model belongs to sewage disposal device, refers to a kind of CASS reaction tank of improvement especially.
Background technology
CASS (Cycl ic Act ivated Sludge System), i.e. cyclic activated sludge system or Cyclic Activated Sludge System is that the one of intermittent activated sludge process develops, can real continuum micromeehanics.CASS pond is the main units applied in cyclic activated sludge system, and because pond body has unique biological selecting area, processing efficiency is high, is widely used in sewage work at present and carries out sewage disposal, especially municipal sewage plant.Because current cyclic activated sludge system exists certain problem in actual motion and design, in conjunction with the change of existing municipal sewage plant influent quality, original technical foundation is improved pond body structure, such as except biological selecting area, increase oxygen-starved area etc., the denitrogenation in further reinforcement CASS pond and phosphorus removal functional, because current CASS belongs to activated sludge process, control although there is partial sludge to reflux, but sludge stream vector is large, the adaptive faculty of impacting trade effluent is poor.
Utility model content
It is low that the purpose of this utility model is to provide sludge yield, the CASS reaction tank of the improvement that can effectively avoid effective microbe to run off.
Overall technology design of the present utility model is:
The CASS reaction tank improved, comprise pond body, longitudinally to arrange and horizontal interval is distributed in the first partition wall in the body of pond and the second partition wall, body inside, pond is divided into biological selecting area, oxygen-starved area and aerobic zone by the first partition wall and the second partition wall successively, first partition wall and the second partition wall offer water hole, in aerobic zone, is provided with water decanter and aeration head; Ball filler of wandering about as a refugee is provided with in described biological selecting area and oxygen-starved area.
Can it is evident that, aeration head needs airduct and blower fan to introduce, and because it belongs to prior art, applicant does not repeat them here.
Concrete technical conceive of the present utility model also has:
More specifically technical scheme is, described ball filler of wandering about as a refugee comprises that to be arranged in biological selecting area first-class from ball filler, is arranged at second in oxygen-starved area from ball filler.
Preferred technical scheme is, the described first-class particle diameter from ball filler is less than the particle diameter of second from ball filler.First-class less from ball packing material size due in biological selecting area, contact area is larger, and bio-film colonization is fast, and biomass is large, and the Cumulate Sum being more conducive to efficient bacterium is selected.Oxygen-starved area bioselection function is taken second place, and second that particle diameter is larger can be selected from ball filler, highlights the function that active sludge and embrane method combine.
For realize current successively from biological selecting area to oxygen-starved area again to aerobic zone, preferred technical scheme is, described water hole comprises and being opened on the first partition wall and the first water hole be communicated with biological selecting area and oxygen-starved area; Be opened in the second water hole be communicated with on the second partition wall and with oxygen-starved area and aerobic zone.
For avoiding current short circuit, ensure that current to be managed fully stop throughout in the district in and to be gone forward side by side row relax, more preferably and comparatively common technical scheme is that the first water hole is opened in the bottom of the first partition wall, the second water hole is opened in the top of the second partition wall.
In order to prevent from wandering about as a refugee, ball filler enters next treatment zone with current through water hole, and preferred technical scheme is that water hole surface is provided with screen cloth.
For realizing backflow and the discharge of mud, preferably and comparatively common technical scheme is that the bottom of described aerobic zone connects the returned sluge input port of biological selecting area by sludge reflux pump, mud return line, reverse flow valve and control valve.
Shore pipe is connect through mud valve in the middle part of described mud return line.
Can it is evident that, multiple treatment zones spaced apart are divided into by dividing plate in each treatment zone, sludge reflux pump, mud return line and by-pass valve control also increase accordingly and adopt mode in parallel, so that realize independent control, do not depart from technical spirit of the present utility model.
Principle of work of the present utility model is as follows:
The water inlet of CASS pond is promoted to biological selecting area by outside lift pump, current carry out pre-treatment and reaction in biological selecting area, realize the screening of dominant bacteria and integrated, then enter oxygen-starved area through the first water hole and carry out denitrification, carry out the hydrolysis of part hardly degraded organic substance simultaneously, enter aerobic zone through the second water hole after having reacted and carry out aerobic reaction, further degradation of organic substances, complete part nitration reaction simultaneously, not only achieve at aeration and sedimentation phase equal time and denitrogenate dephosphorization, also spatially carried out the reinforcement of denitrogenation dephosphorizing, water outlet is discharged through water decanter.Set sludge reflux pump, sludge return pipe and control valve, prevent the loss of biological selecting area and oxygen-starved area mud, because ball of wandering about as a refugee has fixed action to effective microbe, the optional low-capacity pump of sludge reflux pump, sludge reflux amount is little, have sludge pump function simultaneously concurrently, outer row can be carried out to excess sludge.
Technical progress acquired by the utility model is:
1, adopt embrane method and activated sludge process to combine in the utility model in biological selecting area, enhance the effectively biological effective microbe that fixedly avoids and run off, treatment effect is good, avoids simultaneously and selects large model sludge reflux pump, saved electric energy.
2, adopt in biological selecting area ball filler of wandering about as a refugee, because ball internal and external flow field of wandering about as a refugee is different, mass transfer effect is good, and processing efficiency is high, and possess sludge digestion effect, sludge yield is low.
3, adopt filler fixation method, avoid the impact of returned sluge to biological selecting area, filler can carry out gathering and the accumulation of effective microbe simultaneously.
