Description
Technical field
The utility model relates to the technical field of sewage disposal, particularly 3D blodisc.
Background technology
Sanitary sewage is mainly resident's daily life water, containing a large amount of organic pollutants in sewage, if this organic pollutant will affect groundwater quality without process.At present, before sewage effluent, all need except the organic pollutant in decontaminated water, the treatment process adopted has following: (1) A/O technique, A/O technique is using active sludge as bio-carrier, makes sewage reach the object of oxygenation by the effect of blower fan oxygen supply aeration.A establishes mechanical stirring in pond, is back to A pond from O pond, carries out anti-nitration reaction in A pond, and most of nitrate nitrogen is reduced into nitrogen, and by stirring, nitrogen is overflowed from waste water, reaches the object removing ammonia nitrogen; The water outlet of A pond is to O pond, and O establishes blast aeration in pond, removes majority of organic pollutants, and the most ammonia-nitrogen in water inlet is changed into nitrate nitrogen; Can according to the needs of waste water, the activated sludge concentration in adjustment O section pond, by the zoogloea in active sludge, absorption, oxidation organism in Decomposition Wastewater; Organism, ammonia nitrogen removal frank are high.Owing to not having independently sludge recirculation system, thus can not turn out the mud with unique function, the degradation rate of hard-degraded substance is lower; To improve nitric efficiency, must strengthen nitrate recirculation ratio, thus increase working cost, in addition, internal recycle liquid is from aeration tank, and containing certain DO, make A section be difficult to keep desirable anoxic condition, affect denitrification effect, denitrification percent is difficult to reach 90%.Generally speaking, this technique civil engineering and running cost are comparatively large, take up an area more, and follow-up maintenance, complex management.(2) SBR method, SBR method and sequencing batch active sludge, it is a kind of comparatively advanced activated sludge method that developed recently gets up, this treatment process integrates aeration tank, settling tank, continuum micromeehanics, intermittent aeration, settlement of sewage when stopping the supple of gas or steam, skim supernatant liquor, becomes one-period, goes round and begins again.SBR method does not establish settling tank, and without sludge reflux equipment, but SBR method is intermittent operation, need establish multiple processing unit, and water inlet and aeration switch mutually, cause control comparatively complicated.SBR technique requires very high to Automated condtrol, and needs a large amount of electric control valves and mechanical water decanter, and slightly fault can not be run.In order to ensure weir loading, SBR method requires high to water decanter device fabrication, must keep on improving, otherwise very easily cause final outflow water water quality not up to standard during making.Domestic also do not have quality to strain wetting system preferably at present, import equipment buying trouble, and expensive, and maintenance cost is also high from now on simultaneously.In SBR method pond, sludge concentration is measured by concentration meter to control to discharge unnecessary sludge quantity, and current domestic concentration meter quality is still not really up to the mark, causes mud discharging to control more difficult.Because there is several functions in a pond, relevant device must not leave unused then, and the quantity of aeration head and the ability of gas blower must be slightly large, thus add cost of investment and working cost.In addition, SBR belongs to change water level and runs, and power consumption increases, and too increase working cost, its denitrogenation dephosphorizing efficiency is not too high, and sludge stabilization neither be fine, and therefore SBR is not the process choice of this engineering the best.

Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As Figure 1-4, 3D blodisc, it comprises reactive tank 1, transmission shaft 2, back up pad 3 and disc 4, on the top surface of described reactive tank 1 and the both sides being positioned at reactive tank 1 are provided with bearing support 5, between two bearing supports 5, transmission shaft 2 is installed, transmission shaft 2 is tubular shaft, transmission shaft 2 is provided with two back up pads 3, transmission shaft 2 is provided with multiple disc 4 between two back up pads 3, disc 4 is arranged perpendicular to transmission shaft 2, often the spacing of adjacent two discs 4 is all equal, lower part of each disc 4 is all arranged in reactive tank 1, each disc 4 is evenly distributed with multiple grid 8, grid 8 considerably increases the specific surface area of disc 4, be beneficial to the circulation of air, and then add supplementing of microorganism oxygen on disc 4, also be conducive to aging biomembranously to come off simultaneously.Be provided with multiple union lever 6 between two described back up pads 3, union lever 6 runs through disc 4 and arranges, and union lever 6 serves the effect of firm disc 4.The sidewall of reactive tank 1 is also provided with the water outlet 7 being communicated with reactive tank 1, water outlet 7, for discharging the sewage after filtering organic pollutant, makes sewage enter in subsequent processing device.
Described disc 4 adopts modified engineered plastic to make, have light weight, corrosion-resistant, be easy to biofilm, the character such as indeformable.
Working process of the present utility model is as follows: first the lower half circle of disc 4 be partially submerged in and be full of in the reactive tank 1 of sewage, transmission shaft 2 is moved with certain linear velocity not stall, the contact sewage that disc 4 is replaced and air, through cultivating after a while, disc 4 can be attached with the microbial film of microorganism composition, i.e. the microorganism of bacterium and mushroom, microfauna growth reproduction on the grid of disc 4 of protozoon one class.In operational process, when in the sewage in disc 4 contact reacts groove 1, the microbial film be attached on disc 4 fully contacts with the organism in sewage and is adsorbed, dissolved oxygen in the outer moisture film of simultaneously stability microbial film, by organic substance decomposing under the effect of biological enzyme, the nutrient that microorganism utilizes decomposing organic matter to produce in this course carries out self-reproduction, maintains biomembranous quantity.When disc 4 leaves sewage, disc 4 surface forms thin layer moisture film, and air constantly dissolves and enters in moisture film, improves moisture film oxygen concentration of ordinary dissolution.Microbial film replaces contact with sewage, air, forms the process of a continuous print oxygen uptake, absorption, oxygenolysis, reaches water purification object by the continuous process organism gone round and begun again like this.When after the biofilm development on disc 4 to certain thickness, the microbes of contact disc 4 end carries out anaerobic metabolism because of anoxic, innerly forms anaerobic layer (anaerobic microbial film), and the existence due to aerobic layer and anaerobic layer reaches the effect of removal of ammonia and nitrogen.Constantly peel off under the souring that the gas of the shearing that microbial film aging gradually produces when dial rotation and generation and aeration are formed, bring the growth of true tumor film, thus make the activity that microbial film keeps higher always.Now, the microbial film come off flows out outside reactive tank 1 through water outlet 7, is removed by the sedimentation of post precipitation equipment.
