Background technology
In sewage treatment process, settling apparatus is the organism most important link separation with water in water technology, and its equipment operation condition has directly affected effluent quality.The pattern that settling tank is conventional has: horizontal sedimentation tank, tube settler, radial-flow sedimentation tank, wherein horizontal sedimentation tank floor space is large, spoil disposal difficulty, tube settler at mud, because precipitation is insufficient, stop up when light by easy accumulations, radial-flow sedimentation tank use separately pool area greatly, sedimentation speed slowly, deposition efficiency is not high.So need one to there is High-rate sedimentation, reduce medicament and use, widely used efficient sedimentation tank.
Utility model content
The purpose of this utility model is prior art deficiency, provides a kind of and have coagulation, mixing, flocculates, is precipitated as the micro-sand circulating sedimentation tank of sewage disposal of one, and settling tank floor space reduces, and realizes micro-sand circulation, accelerates sedimentation speed, reduces medicament and uses.
The purpose of this utility model is achieved through the following technical solutions: the micro-sand circulating sedimentation tank of a kind of sewage disposal comprises the coagulation basin, mixing pit, flocculation basin, settling tank and the clean water basin composition that connect successively; The top of described mixing pit is provided with rotational flow grit chamber; The bucket of described settling tank bottom is connected with rotational flow grit chamber by micro-sand sludge pipe, and is provided with sludge reflux pump on the pipeline between bucket and rotational flow grit chamber; The feed-water end of described settling tank is provided with scum silica frost receiving tank.
In described flocculation basin, be provided with frame flocculation stirring machine.
The top of described rotational flow grit chamber is provided with mud discharging pipe, and is provided with sand-returning pipe bottom rotational flow grit chamber, and sand-returning pipe is connected with mixing pit.
Further, the top in described settling tank is provided with inclined tube filler, and is provided with supernatant liquor receiving tank above inclined tube filler.
The utility model compared with prior art has the following advantages and beneficial effect:
1, adopt Mechanical coagulation, machinery flocculation, mixing pit in the middle of increasing, mixing pit carries out micro-sand and adds and circulate;
2, adopt rotational flow grit chamber by micro-sand separation utilization in mud, can reduce medicament and use, improve deposition efficiency, reduce by the sludge quantity of swash plate, reduced the generation that swash plate stops up;
3, micro-sand is accelerated sedimentation speed, at settling tank, has increased the upward flow inclined tube theoretical based on " shallow pond precipitation ", greatly reduces settling region floor space, show the smooth spoil disposal that is beneficial to, upflow velocity is large, and surface load is high, the features such as sedimentation effect is good, have improved settling tank deposition efficiency.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is floor map of the present utility model.
In accompanying drawing, corresponding Reference numeral is: 1, coagulation basin, 2, mixing pit, 3, settling tank, 4, coagulating agent adding set, 5, coagulation stirrer, 6, flocculant adding apparatus, 7, flocculation stirring machine, 8, frame flocculation stirring machine, 9, flocculation basin, 10, inclined tube filler, 11, mud scraper, 12, supernatant liquor receiving tank, 13, clean water basin, 14, sludge reflux pump, 15, micro-sand sludge pipe, 16, water inlet pipe, 17, rising pipe, 18, rotational flow grit chamber, 19, mud discharging pipe, 20, sand-returning pipe, 21, scum silica frost receiving tank.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment: as shown in Figures 1 and 2, the utility model comprises that the coagulation basin 1, mixing pit 2, flocculation basin 9, settling tank 3 and the clean water basin 13 that connect successively form; The top of described mixing pit 2 is provided with rotational flow grit chamber 18; The bucket of described settling tank 3 bottoms is connected with rotational flow grit chamber 18 by micro-sand sludge pipe 15, and is provided with sludge reflux pump 14 on the pipeline between bucket and rotational flow grit chamber 18; The feed-water end of described settling tank 3 is provided with scum silica frost receiving tank 21.
In described flocculation basin 9, be provided with frame flocculation stirring machine 8.
The top of described rotational flow grit chamber 18 is provided with mud discharging pipe 19, and rotational flow grit chamber 18 bottoms are provided with sand-returning pipe 20, and sand-returning pipe 20 is connected with mixing pit 2.
Further, the top in described settling tank 3 is provided with inclined tube filler 10, and is provided with supernatant liquor receiving tank 12 above inclined tube filler 10.
Principle of work of the present utility model is: the former water of pending precipitation enters in coagulation basin 1 by water inlet pipe 16, coagulating agent adding set 4 adds coagulated agent, such as polymerize aluminum chloride etc., under the effect of coagulation stirrer 5 with sewage in suspended substance short mix, by in and the negative charge of particle surface make particle " de-steady ", form little flco and then enter mixing pit 2.
In mixing pit 2, by flocculant adding apparatus 6, add flocculation agent, such as polyacrylamide etc., while is passed through sludge reflux pump 14 suction rotational flow grit chambers 18 from the mud in settling tank 3, the sand-returning pipe 20 of rotational flow grit chamber 18 bottoms loops back micro-sand in mixing pit 2, micro-sand is flocculated agent parcel together with particle in water, then at flocculation basin 9, constantly increase, micro-sand increases the weight of flco, is conducive to rapid precipitation.
