Abstract
The utility model discloses an anaerobism pond sewage treatment system, anaerobism pond including a plurality of adjacent settings to and at the dive mixer that every anaerobism pond water inlet homonymy set up, be equipped with the sludge pump in first anaerobism pond, and be equipped with the connecting tube respectively between sludge pump and other all the anaerobism ponds except that first anaerobism pond, be equipped with switching valve on the every connecting tube, every connect duct extension to its anaerobism pond that corresponds in with region dive mixer diagonal angle, every connecting tube is located the last branch connection of underwater regional section of anaerobism pond has the hose. This system utilizes high -velocity flow and hose free swing, has solved mud sedimentary problem in the anaerobism pond. Even if make the dive mixer of smaller power also not have a condition of sludgd deposition, very big saving the input cost.
Description
Technical field
The utility model belongs to sewage disposal technology, is specifically related to a kind of anaerobic pond Sewage treatment systems.
Background technology
Utilize the effect of anerobe in anaerobic pond, organism be hydrolyzed, acidifying and methanation, remove the organism in waste water, and improve the biodegradability of sewage, be conducive to follow-up aerobic treatment.
General anaerobic pond is designed to multiple adjacent rectangle form pool, and influent side arranges 1 diving mixer.If in anaerobic pond design, because the design power of diving mixer is not enough, in the middle of actual motion, affect by sludge concentration, backflow, maintenance of equipment etc., the easy settled sludge in anaerobic pond diving mixer diagonal angle place.Sludgd deposition causes a large amount of mud dead on the one hand and floats, and causes the presentation of improper operation; On the other hand because settled sludge occupies active sludge treatment space, anaerobic pond is reduced and even loses treatment effect.
In order to make up the defect that design power deficiency causes, if change the diving mixer of more high-power, larger impeller, then cost can be made significantly to increase.
Utility model content
For the problems referred to above, the utility model aim to provide a kind of when ensure anaerobic pond not settled sludge the Sewage treatment systems that significantly reduces costs.
The technical scheme that the utility model is dealt with problems is: a kind of anaerobic pond Sewage treatment systems, comprise multiple anaerobic pond be disposed adjacent, and at the diving mixer that each anaerobic pond water-in homonymy is arranged, sludge pump is provided with in the first anaerobic pond, be respectively equipped with connecting tube between sludge pump and other all anaerobic pond except the first anaerobic pond, every root connecting tube is provided with opening-closing valve.
Described every root connecting tube extend in the anaerobic pond of its correspondence with the region at diving mixer diagonal angle.
Every root connecting tube is positioned at anaerobic pond area segments upper bifurcation under water and is connected with flexible pipe.
Connecting tube is positioned at the flexible pipe of anaerobic pond under water in area segments and is interval with many successively.
Under avoiding the long-time not running status of system, sludge blockage pipeline, the free end of described flexible pipe is provided with check valve.
Described sludge pump is arranged at the supernatant layer position of the first anaerobic pond.Supernatant liquor dissolved oxygen concentration is low, can not affect greatly other anaerobic pond dissolved oxygen.
This system work process is, when there is sludgd deposition in the diagonal zones of certain anaerobic pond diving mixer, open the opening-closing valve on corresponding connecting tube, the water of the first anaerobic pond is delivered to by connecting tube the flexible pipe that arranges in corresponding anaerobic pond with sludge pump and from hose free end ejection, the mud of high velocity flow to deposition effectively impacts;
Meanwhile, hose free end can do random motion, thus drives whole piece flexible pipe to do random motion, and the mud of motion to deposition of flexible pipe has carried out effective stirring.The mud of deposition, under the impact dual function of the stirring of flexible pipe, current, cannot deposit, thus effectively mix with sewage, again recover the processing capacity of anaerobic pond.
Opening-closing valve without anaerobic pond can be opened simultaneously; Also can open during difference, isolated operation.As long as there is sludgd deposition namely to run.
Unusual effect of the present utility model is:
1. by arranging flexible pipe at the diagonal angle of anaerobic pond diving mixer, utilize high velocity flow to wash away the mud of deposition, the principle simultaneously utilizing flexible pipe swingable under effect of water pressure stirs the mud of deposition, avoids the deposition of mud in anaerobic pond.
By to the simple change in anaerobic pond system architecture, even if make the diving mixer of smaller power also there is not the situation of sludgd deposition, save input cost greatly.
2. the water of sludge pump suction is the first anaerobic supernatant, and dissolved oxygen concentration is low, can not affect greatly other anaerobic pond dissolved oxygen.And water source, from system self, not from extraneous diversion, can not cause water resource waste.
3. each hose end all installs check valve, under the long-time not running status of system can be avoided, and sludge blockage pipeline.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the orthographic plan of anaerobic pond Sewage treatment systems.
Fig. 2 is the piping arrangement stereographic map in Fig. 1.
In figure: 1-first anaerobic pond, 2-water-in, 3-diving mixer, 4-sludge pump, 5-connecting tube, 6-opening-closing valve, 7-flexible pipe, 8-check valve, 9-second anaerobic pond, 10-the 3rd anaerobic pond, 11-sludgd deposition district.
Embodiment
As shown in Fig. 1 ~ 2, a kind of anaerobic pond Sewage treatment systems, comprise three anaerobic ponds be disposed adjacent, and at the diving mixer 3 that each anaerobic pond water-in 2 homonymy is arranged, supernatant layer position in the first anaerobic pond 1 is provided with sludge pump 4, be respectively equipped with connecting tube 5 between sludge pump 4 and the second anaerobic pond 9, the 3rd anaerobic pond 10, every root connecting tube 5 is provided with opening-closing valve 6.
Every root connecting tube extend in the anaerobic pond of its correspondence with the region at diving mixer 3 diagonal angle, namely sludgd deposition district 11.
Every root connecting tube 5 is positioned at anaerobic pond area segments upper bifurcation under water and is connected with flexible pipe 7, and flexible pipe 7 is interval with many successively.The free end of described flexible pipe 7 is provided with check valve 8.
This system work process is, when there is sludgd deposition in the second anaerobic pond 9, open the opening-closing valve 6 on this anaerobic pond connecting tube 5, the water of the first anaerobic pond 1 is delivered to the flexible pipe 7 in the second anaerobic pond 9 by connecting tube 5 with sludge pump 4 and from the ejection of flexible pipe 7 free end, the mud of high velocity flow to deposition effectively impacts;
Meanwhile, flexible pipe 7 free end can do random motion, thus drives whole piece flexible pipe 7 to do random motion, and the mud of motion to deposition of flexible pipe 7 has carried out effective stirring.The mud of deposition, under the impact dual function of the stirring of flexible pipe 7, current, cannot deposit, thus effectively mix with sewage, again recover the processing capacity of anaerobic pond.
In like manner, when sludgd deposition appears in the 3rd anaerobic pond 10, open the opening-closing valve 6 on this anaerobic pond connecting tube, also effectively can avoid sludgd deposition.
The opening-closing valve 6 of second, third anaerobic pond can be opened simultaneously, also can open during difference.
