The garbage leachate treatment device of the present embodiment also comprises auxiliary processing unit 40, described auxiliary processing unit 40 is sludge treatment equipment 41, the upflow anaerobic sludge blanket process 21 of sludge treatment equipment 41 and Main Processor Unit 20, one-level flocculation sedimentation tank 22, aeration tank 23, contact-oxidation pool 24 and secondary flocculation sedimentation tank 25 are connected respectively, the mud that these integral parts produce is processed by sludge treatment equipment 41, and unification is delivered to landfill district.
Concrete, upflow anaerobic sludge blanket process (Up-flow Anaerobic Sludge Bed, be called for short UASB), its technique has the dual characteristics of anaerobism filtration and anaerobic activated sludge method, adaptability for different solid content sewage is also strong, and its structure, operation maintenance management are relatively simple.UASB is made up of sludge reaction district, gas-liquid-solid three-phase separator (comprising settling region) and air chamber three part.In reaction zone, bottom, retain a large amount of anaerobic sludge, the mud with good sedimentation function and cohesion performance forms sludge blanket in bottom.Sewage to be processed carries out mixing from the inflow of anaerobic mud bed bottom with mud sludge blanket and contacts, and the organism in the microbial decomposition sewage in mud, is converted into biogas it.Biogas is constantly released with micro-bubble form, micro-bubble is in uphill process, continuous merging, form larger bubble gradually, rise on Sludge Bed top together with water enter triphase separator because the stirring of biogas forms the thinner mud of sludge concentration, when biogas encounters the reflector of separator bottom, be folded to the surrounding of reflector, then air chamber is entered through water layer, concentrate on air chamber biogas, derive with conduit, solid-liquid mixed solution enters the settling region of triphase separator through reflection, mud in sewage flocculates, particle increases gradually, and sedimentation under gravity.The mud natural pond be precipitated on skew wall skew wall and slides back in anaerobic reaction district, makes the mud that in reaction zone, accumulation is a large amount of, and the process water outlet after being separated with mud is overflowed from overflow weir top, settling region, then discharges Sludge Bed.The major advantage of UASB is:
1) in UASB, sludge concentration is high, and mean sludge concentration is 20-40gVSS/L;
2) organic loading is high, and hydraulic detention time is short, and when adopting mesophilic digestion, volumetric loading can reach 10kgCOD/m
3.d left and right;
3) Sludge Bed does not fill out carrier, saves cost and avoids because stifled match problem occurs filler;
4) establish triphase separator in UASB, usually do not establish settling tank, the mud that precipitated district separates comes back in Sludge Bed reaction zone.
What device for catalyzing and oxidating ozone adopted is catalytic ozonation technology based on heterogeneous catalysis technology.Wherein physical catalyze is mainly based on the magnetization treatment of water, the magnetization treatment of water significantly can change the structure formation of water molecules, thus change the essential property of water, the paramagnetism feature of oxygen is mainly utilized in this project, by increasing the saturation solubility of water oxygen to the magnetization treatment of water, reduce the mode of diamagnetic material saturation solubility in water, improve the solubility property of ozone in water and the solubility property of water system itself, improve the speed of ozone oxidation reaction.First the selection of chemical catalyst is considered the biochemical reaction operation in downstream, catalyst choice is considered the problem of resistance of microorganism, secondly consider the characteristic of reaction substrate, greatly, different catalysts all requires different pH value range for the catalyzed reaction of catalyzer and water system pH value relation.The reaction mechanism more complicated of catalyzer, especially in the indefinite reaction of this substrate of sewage disposal, in simple terms, mainly through promoting that ozone plays a role to the reaction of free radical.
The utility model adopts membrane bioreactor, membrane separation technique is efficiently combined with biological treatment, and its origin carries out solid-liquid separation with the second pond that membrane separation technique replaces in activated sludge process.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.
