Description
Technical field
The present invention relates to technical field of sewage, relate in particular to a kind of sewage-treatment plant.
Background technology
Along with the reinforcement of domestic and international Urbanization Construction dynamics, the dilatation speed in cities and towns is more and more faster, and day increasinglyThe fast generation of urbanization population, along with the raising of people's living standard, in the sanitary sewage discharging notBut contain a certain amount of organic matter and ammonia nitrogen, and contain the pollutant such as germ, phosphorus, if do not dealt carefully with,To have a strong impact on surrounding environment. Therefore, present cities and towns and rural environmental pollution are very outstanding and severe.Although domestic Some Cities And Towns and rural area village village is supporting Sewage Treatment Facilities, invests high, power consumptionGreatly, without dephosphorization process, treatment effect-as, operational administrative is loaded down with trivial details. Therefore we have invented a kind of equipmentReduced investment, dephosphorization process is new, operating cost is low, treatment effect is good, the small towns of non-secondary pollution life dirtyWater treatment plant's (station) technique and complexes thereof.
Current conventional domestic sewage processing method mainly contains:
1. biological contact oxidation process technique
Its advantage has:
(1) biological concentration is high, and the ability of anti-shock loading is stronger;
(2) mass transfer condition is good, and coefficient of oxygen utilization is high, and power consumption is few;
(3) sludge creation amount is less, and does not have the problem of sludge bulking;
(4) do not need sludge reflux, operating cost is low;
(5) specific area of filler is large, and floor space is less.
Its shortcoming is:
(1) on filler, biomembrane actual quantity becomes with BOD loading. BOD loading is high, biomembrane numberAmount is many; Vice versa;
(2) biofilm biomass increases with load, loads too high, and biomembrane is blocked up, fills out at someIn material, be easy to stop up;
(3) because filler setting makes the structure of oxidation pond comparatively complicated, the installation and maintenance of aerator is notAs activated sludge process is come conveniently;
(4) filler is selected improperly, can have a strong impact on the normal use of contact oxidation method technique.
2.SBR method technique
Its advantage has:
(1) desirable plug-flow process increases biochemical reaction motive force, and efficiency improves, anaerobism, good in pondOxygen is in alternating state, good purification;
(2) operational effect is stable, and sewage precipitates under desirable inactive state, needs short, efficiency of timeHeight, effluent quality is good;
(3) anti impulsion load, has the processing water of delay in pond, sewage is had to dilution, cushioning effect, hasThe impact of the effect opposing water yield and organic dirt;
(4) the each operation in technical process can be adjusted according to water quality, the water yield, flexible operation;
(5) treatment facility is few, simple structure, convenient operation and maintenance management;
(6) in reaction tank, there is DO, BOD5 concentration gradient, effectively control activated sludge bulking;
(7) SBR method system itself is also suitable for combined type building method, is beneficial to the enlarging of waste water treatment plantAnd transformation;
(8) denitrogenation dephosphorizing, suitably Controlling operation method, realizes aerobic, anoxic, anaerobic state alternately,There is good Nitrogen/Phosphorus Removal;
(9) technological process is simple, cost is low. Main equipment only has a batch-type batch reactor, without twoHeavy pond, sludge reflux system, regulating reservoir, preliminary sedimentation tank also can omit, characteristics of compact layout, small accommodation area.
Its shortcoming is:
(1) automation control requires high;
(2) when water discharge time short (when intermittent drainage), and draining, require not stir precipitating sludge layer, because ofAnd need special drainage equipment (straining hydrophone), and very high to straining the requirement of hydrophone;
(3) equipment for after-treatment requires large: as very large in sterilizing equipment decontaminating apparatus, contact chamber volume is also very large, pumping equipmentAs also very large in drainage pipeline;
(4) owing to not establishing preliminary sedimentation tank, easily produce scum silica frost, scum problem is not yet properly settled.
3.A/O biological treatment
Its advantage has:
(1) flow process is simple, does not need additional carbon and rear aeration tank, taking raw sewage as carbon source, builds and fortuneRow expense is lower;
(2) denitrification is front, nitrated rear, establishes interior circulation, using the organic substrates in raw sewage as carbonSource, effective, anti-nitration reaction is abundant;
(3) aeration tank, rear, makes denitrification residue be able to further removal, has improved processing water water quality;
(4) A section stirs, and only rises and makes sludge suspension, and avoid the increase of DO. The leading portion of O section adopts strongAeration, back segment reduces tolerance, the DO content of interior circulation fluid is reduced, to ensure the anaerobic condition of A section.
Its shortcoming is:
(1) owing to there is no independently sludge reflux system, thereby can not turn out the dirt with unique functionMud, the degradation rate of hard-degraded substance is lower;
(2), if will improve nitric efficiency, must strengthen nitrate recirculation ratio, thereby strengthen operating cost. From outside,Interior circulation fluid, from aeration tank, contains certain DO, makes A section be difficult to the anaerobic condition that keeps desirable,Affect denitrification effect, denitrification percent is difficult to reach 90%;
(3) influence factor hydraulic detention time (nitrated > 6h, denitrification < 2h), recycle ratio MLSS(> 3000mg/L), sludge age (> 30d), N/MLSS rate of load condensate (< 0.03), water inlet total nitrogenConcentration (< 30mg/L).
