Description

Combined type HBF module reactor and sewage treatment process
Technical field
The present invention relates to technical field of sewage, relate in particular to a kind of combined type HBF module reactor and sewage treatment process.
Background technology
Country's " 12 " Plan carry forward vigorously Urbanization Construction, accelerate the strategy and policy of cities and towns macroeconomic and social development.Environmental protection is always the most important thing of Urbanization Construction, but the reason such as limited due to technical capacity, that cost of investment is too high, output can't produce a desired effect, serious problem of environmental pollution has appearred in Development of China's Urbanization, particularly the sewage handling problem inseparable with daily life.
Intermittent activated sludge process (Sequencing Batch Reactor is called for short SBR) claims again sequencing batch active sludge, is a kind of waste water treatment process that is different from traditional activated sludge process.In operational process, in the working time in each stage, reactor, the variation of mixeding liquid volume and running status etc. can change flexibly according to character, effluent quality, effluent characteristics and the operation function requirement etc. of concrete sewage due to SBR.For the sbr reactor device, just sequential control is without the spatial control obstacle, so can control flexibly.Therefore, SBR technological development speed is exceedingly fast, and derives many kinds of New type of S BR treatment process.
But present SBR operation still has following shortcoming:
(1) single sbr reactor device needs larger equalizing tank.
When (2) the processing water yield was large, the unmatched problem of water and intermittent water inflow was difficult to solve.Need the parallel running of many cover sbr reactor devices this moment, valve switches frequent, and schedule of operation is complicated.
(3) during big yield, advantage is not obvious.No matter the water yield is big or small, and the initial cost of SBR method and working cost are all suitable with oxidation ditch, but initial cost reduces by 20% left and right than traditional activated sludge process.The water yield hour, the working cost of SBR is economized 20% left and right than traditional activated sludge process, but the water yield is when large.SBR working cost and Traditional Method are close.As seen SBR has lost advantage to big yield.
(4) lness ratio of plant is high.
(5) drag losses of sewage lifting is larger.
Therefore, those skilled in the art is devoted to develop a kind of novel, efficient aerobic treatment technology HBF technique (Honess Hybrid Biological﹠amp; Fixed film Technology is called for short HBF).

What need supplementary notes is, above-mentioned enzyme in the present invention floats filler, can select notification number is that the CN101633529B name is called the ionic enzymatic suspended filler that " the ionic enzymatic suspended filler manufacture method that is applied to high-leveled and difficult wastewater treatment " manufacturing obtains, and this paper repeats no more.
In sum, the beneficial effect of combined type HBF module reactor of the present invention and sewage treatment process is as follows:
1) structure of the present invention and technical process are simple, civil engineering and investment are low, without preliminary sedimentation tank, second pond, level of automation is high, and in the pond, the microorganism total amount is comprised of the active sludge of suspended state and the microbial film of settled organism simultaneously, more than sludge concentration can reach 8000mg/L, even under the situation that biological load does not increase, also make system can bear higher volumetric loading, it is low far beyond traditional biochemical treatment system that Gu Chi holds, and makes civil engineering take up an area and invest far below existing biochemical processing process.
2) for single SBR pond for being interrupted water inlet, but for the bed rearrangement reactor, realized continuous water inlet, water outlet, make whole Process for Effluent continuous uniform, convenient operation and management.
3) pool inner water position substantially constant, Aerobic Pond (aerobic module) is in normal aeration state, has increased the pond capacity utilization, has improved the utilization ratio of equipment; Gas blower pressure-stabilisation, efficient are high; Atmospheric oxygen trans-utilization rate is high, and volumetric loading and sludge loading are high.Simultaneously, due to the filling of the floating filler of enzyme, the bubble that discharges for the bottom micro-pore aeration plays secondary shearing and prevents and poly-system, has correspondingly extended air and water, microorganism mass transfer time; The formed turbulent hydraulic shear of filler interception makes the refinement of bubble height and Uniform Dispersion, has determined that in the pond, the trans-utilization rate of atmospheric oxygen is high.Enough dissolved oxygens are the conditions that guarantees the heavy-duty service of aerobe treatment system, and this is also one of advantage of the present invention.
4) good effect of separating solid from liquid, excess sludge production is less, reduces sludge treatment and disposal costs.Because the contained protozoon composition of the microbial film mud that peels off is more larger with proportion, and the mud granule individuality is larger, thereby has good sludge settling property, is easy to solid-liquid separation.Because food chain in microbial film is longer, thereby surplus sludge volume obviously reduces, particularly the microbial film of the floating filler of enzyme is thicker than traditional biomembrance process, and inner anerobe can be decomposed the excess sludge that the part aerobic processes is synthesized, thereby total surplus mud is greatly reduced.
5) the present invention is equivalent to a complete mixing reactor during intaking, has powerful dilution function, thereby have stronger anti impulsion load and an anti-poisonous substance ability, belong to quiescent setting during precipitation, deposition condition is good, higher sludge concentration can be accumulated in reactor, thereby second pond can be do not established.
6) good nitrogen removal performance.The floating filler of enzyme is set, there is the stable stereo ecological bit pattern of different strain in reactor, the nitrification and denitrification process can organically combine, and carry out simultaneously, thereby the pH that energy reduction system occurs in the nitration denitrification process changes, reduce denitrification process to carbon source and alkalinity demand, the denitrogenation degree is high, effect stability.Simultaneously, technique has been strengthened denitrification process by special hypoxia response district, and in addition, SBR pond non aerated phases precipitating sludge bed also has certain denitrification, thereby makes system that good denitrification effect be arranged.
7) according to the biological respinse principle of dynamics, adopt the series operation of many ponds, make sewage reactor mobile present whole plug-flow and in different zones the Complex Flow Status for mixing fully, not only guaranteed stable treatment effect, and improved capacity utilization.
Technique of the present invention is on the sequencing batch active sludge basis, advantage in conjunction with biomembrance process, a kind of combined type HBF module reactor and the sewage treatment process developed as the basis take biological respinse principle of dynamics and rational hydraulics, realize that technical process is simple, flexible, even water distribution, form good microorganism, sewage reaction system, treatment effect is more efficient; And the setting of having saved settling tank, reduced investment, level of automation is high; Adopt simultaneously the combined type module structure, have characteristics of compact layout, take up an area less, build, operational management advantage more easily, be particularly useful for municipal effluent and require the processing of denitrogenation dephosphorizing
