For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, Figure 1 shows that the schematic diagram of an embodiment of a kind of percolate Sewage treatment systems of the present utility model.In the present embodiment, percolate Sewage treatment systems is comprised the equalizing tank 1, baffling type anaerobic reactor 5, anaerobic biofilter 8, the MBR that are connected by pipeline successively and reacts anoxic pond 10, MBR reaction tank 13, collecting tank 26, nanofiltration system 22 and coagulating settling tank 19; Be provided with lift pump 2 bottom equalizing tank 1, lift pump 2 exports and connects baffling type anaerobic reactor 5 by pipeline; The built-in vertical flow deflector 7 of baffling type anaerobic reactor 5, vertical flow deflector 7 lower end is provided with bending 6; Packing layer is provided with in anaerobic biofilter 8; MBR reacts bottom anoxic pond 10 and is provided with underwater stirrer 11; Be provided with sludge reflux pump 12 and MBR membrane cisterna 14 bottom MBR reaction tank 13, anaerobic biofilter 8 is connected tracheae with bottom MBR reaction tank 13, tracheae connecting fan 9; Pipeline between MBR reaction tank 13 and collecting tank 26 is provided with suction pump 15; Coagulating settling tank 19 is provided with medical liquid mixer 18, and medical liquid mixer 18 connects polymerize aluminum chloride dosing parts 16, polyacrylamide dosing parts 17 and the dense water rising pipe of nanofiltration system 22; Nanofiltration system 22 connects letdown tank 21 by pipeline; Baffling type anaerobic reactor 5, anaerobic biofilter 8, MBR react anoxic pond 10, MBR reaction tank 13 is all connected sludge thickener 24 by sludge pipe with bottom coagulating settling tank 19, are provided with sludge pump 25 bottom sludge thickener 24.
General handled sewage quality is uneven, and sewage discharge hourly variation factor is comparatively large, therefore need establish equalizing tank 1, equalizing tank 1 object regulates all with the water quality of sewage with to the water yield, cut down peak load, be conducive to next step process, reduce subsequent disposal structures volume and expense of reducing investment outlay.
Baffling type anaerobic answers the built-in vertical flow deflector 7 of device 5, reactor is separated into several reaction chambers of series connection, and each reaction chamber is a relatively independent upflow sludge blanket system, and mud wherein can be exist with granulate form or with cotton-shaped form.Current guide upper and lower baffling to advance by flow deflector 7, and one by one by the mud bed in reaction chamber, the substrate in water inlet fully contacts with microorganism and degraded and remove.
Anaerobic biofilter 8 is equipped with filler, and filler is for microorganism provides the carrier in the surface of apposition growth and the space of suspension growth.When sewage flows through packing layer, wherein organism is retained by anaerobion, adsorbs and metabolic breakdown, finally reaches stabilization, produces biogas simultaneously, forms new microbial film.
Establish biofilm thickness about 1 ~ 3mm on filler that surface-area is very large in anaerobic biofilter 8, add the microorganism of suspension growth, in pond, biosolids amount can reach 20 ~ 30g/L.Add the microbial film residence time long (on average can reach about 100d), thus can bear higher volumetric loading, CODcr volumetric loading is generally 2 ~ 16kgCODcr/ (m3d), and capacity of resisting impact load is stronger.The microbial film that anaerobion grows based on set, not easily runs off, and therefore except normal Inlet and outlet water or suitable refluxing portion water outlet, does not need sludge reflux and uses whipping device.
MBR reaction tank 13 is divided into two portions, is biological A pond (anoxic) and biological O pond (catalytic oxidation) respectively.
A/O is the abbreviation of Anoxic/Oxic, and its superiority is that also having certain denitrogenation dephosphorizing function, is by the pre-treatment of anaerobic hydrolysis technology for active sludge except making organic pollutant obtain except degraded, so A/O method is the activated sludge process improved.
Leading portion anoxic section and back segment aerobic section are cascaded by A/O technique, A section DO(dissolved oxygen) be not more than 0.2mg/L, O section DO=2 ~ 4mg/L.Anoxic section heterotrophic bacterium, the suspended contaminant such as the starch in sewage, fiber, carbohydrate and dissolved organic matter are hydrolyzed to organic acid, larger molecular organics is made to be decomposed into small organic molecule, insoluble organism changes into dissolved organic matter, when these products through anaerobic hydrolysis enter Aerobic Pond carry out aerobic treatment time, improve the biodegradability of sewage, improve the efficiency of oxygen; The pollutent such as protein, fat carried out ammonification (N in organic chain or the amino in amino acid) anoxic section heterotrophic bacterium to dissociate ammonia (NH3, NH4+), under sufficient oxygen supply condition, the nitrification of autotrophic bacteria is by NH3-N(NH4+) be oxidized to NO3-, A pond is back to by backflow control, under anoxic conditions, NO3-is reduced to molecular nitrogen (N2) and completes C, N, O circulation in ecology by the denitrification of heterotrophic bacteria, realizes sewage harmless treatment.
Anoxic pond front, the organic carbon in sewage utilize by denitrifying bacteria, can alleviate the organic loading of Aerobic Pond thereafter, the basicity that anti-nitration reaction produces can compensate in Aerobic Pond and carries out the demand of nitration reaction to basicity.Aerobic after anoxic pond, the residual organic pollutant of denitrification can be made to be removed further, improve effluent quality.The clearance comparatively Gao Keda more than 90 ~ 95% of BOD5, but Nitrogen/Phosphorus Removal is slightly poor, and nitric efficiency 70 ~ 80%, dephosphorization only has 20 ~ 30%.
Biological contact oxidation process processes technique ripe and stable in trade effluent at present.Microbial process is relied on to remove a large amount of organism and suspended substance, reduce COD and BOD5, comprehensive aeration type contact oxidation method is selected at this, the method makes certain biologic packing material be immersed in water, space between filling surface and filler generates membranaceous biological activated sludge, and waste water is in contact with it thus is purified, for making purification ratio more abundant, waste water must be made fully to circulate, repeatedly with biofilm contact.Because filler and microbial film are all immersed in water, at the bottom of pond, arrange air-diffuser uniformly, air directly enters packing area and fully contacts with microbial film, and it is washed away, microbial film renewal frequency is high, and activity is strong and stable, and aeration also plays the function making waste water circulation.
Built-up type many idle loops filler is set in biological contact oxidation pond.This is because:
1. packing specific area is large, and microorganic adhesion space is large, and coefficient of oxygen utilization is high;
2. its comprehensive cost is about 1/2 of honeycomb filler, 2/3 of semi soft packing.
MBR membrane bioreactor is the Novel state Waste Water Treatment of membrane separation technique and biologic treating technique combination.Replace traditional biological treatment technology end second pond with membrane module, in bio-reactor, keep high reactivity sludge concentration, improve biological treatment organic loading, thus reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.Active sludge in the membrane separation plant entrapping tank in aerobe pond and larger molecular organics are immersed in main utilization.
This technique not only reaches the object of mud-water separation effectively, and has the incomparable advantage of tertiary sewage treatment traditional technology:
1, carry out solid-liquid separation efficiently, its separating effect is much better than traditional settling tank, and effluent quality is good, goes out water suspension and turbidity close to zero, can direct reuse, achieves sewage recycling.
2, the efficient crown_interception of film, makes microorganism be trapped in completely in bio-reactor, and realization response device hydraulic detention time (HRT) is separated completely with sludge age (SRT's), runs and controls to stablize flexibly.
3, because the aeration tank of traditional wastewater process and second pond unite two into one by MBR, and instead of whole process facility of tertiary treatment, therefore significantly can reduce floor space, save construction investment.
4, be beneficial to retaining and breeding of nitrobacteria, system nitrification efficiency is high.Also deamination and phosphorus removal functional can be had by the change of operation scheme.
5, because mud age can be very long, thus the degradation efficiency of hardly degraded organic substance is greatly improved.
6, reactor runs under age at high volumetric loading, low sludge loading, long mud, and excess sludge production is extremely low, because mud age can endless, can realize zero sludge discharge in theory.
7, system realizes PLC control, convenient operation and management.
Nanofiltration is a kind of membrane separation technique between ultrafiltration and reverse osmosis, and it impels water molecules reverse osmosis by pressure, with the method for concentrated solution or waste water.The method advantage is as follows: 1. do not need heating, do not have phase transformation; 2. less energy consumption; 3. equipment volume is little, simple to operate, strong adaptability; 4. pollution is not produced to environment.
