Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, bio-pharmaceuticals sewage purification system of the present utility model comprise the grid canal, the equalizing tank 1 that catchments, hydrolytic tank 2, two-part contact-oxidation pool, settling tank 5 and sludge thickener 6.
Wherein, described grid canal is collected to the equalizing tank that catchments with waste water, in the process of carrying, utilizes grid filtering large volume rubbish simultaneously, avoids follow-up water treatment is consisted of impact.
The described equalizing tank 1 that catchments plays balanced amount of inlet water and water quality effect, it can be regulated inhomogeneous treatment system is produced of discharge of wastewater and impact, also be provided with simultaneously cover aeration agitation system and a waste water lifting pump in the described equalizing tank that catchments, described aeration agitation system comprises aerator, submersible aerator, agitator and impeller, mud behind aeration so that organism oxidation and nitration reaction can occur in a large number and decompose, simultaneously can be so that the sewage in it be even to the mixing effect of the equalizing tank that catchments, avoid the processing that produces in the water treatment procedure of different pollution levels inhomogeneous, affect decontamination effect improving.
The equalizing tank 1 interior water that catchments enters hydrolytic tank 2 by the road by sewage pump 11 liftings after equilibrium, described hydrolytic tank improves the biodegradability of waste water with so that the larger molecular organics in the waste water is degraded to small organic molecule.Simultaneously, for improving its aeration effect, improve the macromolecules degradation rate, also be provided with the first aeration tube 21 in described hydrolytic tank bottom, described aeration tube is communicated with by the road with gas blower 7, and gas blower is blown into aeration tube with sewage in the agitated pool with air, and mud is fully contacted with sewage, avoid at the bottom of the sludgd deposition pond, improve the acidified degradation rate.
Water behind acidified degradation enters contact-oxidation pool, it comprises two contact-oxidation pools, the first contact-oxidation pool 3 and the second contact-oxidation pool 4, contact-oxidation pool is removed small-molecule substance by fixed biofilm and active sludge effect, makes it thoroughly to be degraded to carbonic acid gas and water.Biological contact oxidation process is a kind of bio membrane process between activated sludge process and biological filter, described contact-oxidation pool arranges filler in the pond, the second aeration tube 31 that is communicated with gas blower 7,41 pairs of stirring sewage are set at the bottom of the pond, make body interior sewage in pond be in flow state, to guarantee that sewage fully contacts with filler in the sewage, avoids existing in the biological contact oxidation pond sewage to contact the defective of inequality with filler.Institute of Micro-biology on the filler is aerobic to be supplied with by aeration tube, biofilm development is to certain thickness, the microbes of filler wall carries out anaerobic metabolism because of anoxic, the souring that the gas that produces and aeration form can cause biomembranous coming off, and the growth of promotion true tumor film, at this moment, the microbial film that comes off will flow out outside the pond with water outlet.The characteristics such as that contact-oxidation pool has is energy-efficient, floor space is little, anti impulsion load, operational management are convenient, Effective Raise the energy-saving effect of whole Sewage treatment systems.
Mixed solution after the water treatment in the second contact-oxidation pool enters settling tank 5, preferably, described settling tank is the tube settler that is provided with inclined tube in the settling region, specifically, the parallel pipe or the parallelpiped (or utilizing the honeycomb filler) that utilize in the settling region of flat flow or vertical sedimentation basin are divided into a series of shallow layer precipitating layers, and processed and heavy mud sedimentation is mutually motion and separating in each precipitation shallow-layer.Be divided into contrary (different) to stream, three kinds of different separate modes of concurrent and reverse flow according to its mutual direction of motion.(or in parallel pipe) is equivalent to a very shallow settling tank between per two inclined paralled plates.Its advantage is: utilized lamina flow principle, improved the processing power of settling tank; Shorten the particles settling distance, thereby shortened sedimentation time; Increase the desilting area of settling tank, thereby improved processing efficiency.Described settling tank bottom is formed with back taper mud pooling zone 51 with interim storage mud, and the inverted-cone cavity design has improved the gravity squeezing action, improves sewage sludge solid concentration.
It is to be noted, the increase of the nutritive substances such as nitrogen phosphorus is the major cause of eutrophication, therefore country requires stricter for the discharge index of nitrogen phosphorus in the sewage discharge, the method that has adopted biological phosphate-eliminating to combine with chemical dephosphorization in this programme, the anaerobism of front--aerobic section is biological phosphate-eliminating, back segment arranges total phosphorus on-line monitoring system and medicine system at the settling tank place, guarantees that total phosphorus is up to standard in the water outlet.Medicine system is located at the settling tank position, and main purpose is to control the total phosphorous in the effluent index.Specifically, whole medicine system is the automatic hierarchy of control.Mainly comprise total phosphorus on-line monitoring instrument, PLC system, dosing volume pump, grug feeding jar etc.When phosphorus content is higher than 1mg/L in the water outlet, total phosphorus on-line monitoring system automatic alarm, and signal transferred to the PLC system, the polyacrylamide solution that PLC system control dosing volume pump adds 5% poly-ferric chloride and 1% automatically makes the phosphoric acid salt flocculation sediment in the water outlet, to reduce phosphorus content.When total phosphorous in the water outlet≤1mg/L, medicine system stops dosing automatically.Wherein, total phosphorus on-line monitoring instrument and the even commercially available prod of dosing volume pump no longer launch to describe at this.
Discharge and be disposed to municipal pipeline from top through the clear water behind the settling tank, the mud that the bottom is deposited on the mud pooling zone enters sludge thickener 6 through sludge pipe, the mud that becomes a mandarin flows into the sludge thickener middle part by pipe core, the supernatant liquor of sludge thickener passes back into the equalizing tank that catchments and again processes, and the mud after concentrating is discharged at the bottom of the pond.
Further, for improving the flowability of catalytic oxidation pool inner water, described the second contact-oxidation pool bottom is provided with sludge reflux pump 42 and plays back to hydrolytic tank 2 with the mixed solution with the bottom, improves Nitrogen/Phosphorus Removal by the backflow nitrification liquid, and then realizes efficient decontamination effect improving.
For reducing the number of times of sewage lifting, the utility model is taked the mode of flow by gravity, to reduce pump power, specifically, the liquid level design of the described equalizing tank that catchments is minimum, hydrolytic tank, the first contact-oxidation pool the second contact-oxidation pool, the liquid level of settling tank reduces successively, the liquid level of described sludge thickener is higher than the equalizing tank liquid level of catchmenting, be provided with the flooded zonevvv that is consisted of by annular overflow weir at the inwall top in each pond like this, then in the pond supernatant liquor overflow to flooded zonevvv, then under action of gravity, enter in the next pond or discharging, reduced energy consumption, improve environmental-protecting performance.
The above only is preferred implementation of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
