Technical Field

The utility model relates to the technical field of wastewater treatment, in particular to a sewage treatment system.

Background

With the continuous development of cities in China, various complexes, enterprises and public facilities canteens, school canteens, hotels, food cities and other places with large-scale catering food squares are increased. The food and beverage can generate a large amount of kitchen waste water every day. The kitchen waste water contains kitchen waste and hogwash, and a large amount of animal and vegetable oil is contained in the kitchen waste and hogwash, if the kitchen waste and hogwash are directly discharged into a sewer pipe without being treated and illegally discharged, a large amount of greasy dirt is attached to the pipe wall, and the sewer pipe is reduced in overflow capacity and blocked.

At present, chinese patent publication No. CN211595373U discloses a kitchen waste leachate sewage treatment system, which comprises a first oil-water separator, a first slag separating tank, a kitchen waste regulating tank, a comprehensive regulating tank, a pH regulating tank, a UASB, an anoxic tank, a primary contact oxidation tank, a secondary contact oxidation tank, a primary sedimentation tank, a dephosphorization tank, a secondary sedimentation tank and a clean water tank which are sequentially communicated along the sewage conveying direction. The oil-water separator is used for oil-water separation of sewage to meet the condition that the sewage entering pipeline transportation is difficult to cause agglomeration of animal and vegetable oil and block the pipeline.

In addition, chinese patent publication No. CN213609929U discloses an oil-water separator for treating catering oil-water, which comprises a box body, wherein an end cover is detachably sealed at one side of the box body, a bent plate is arranged on the inner wall of the end cover, and a mixed liquid inlet of the box body is opposite to the bent plate. When the sewage treatment device is used, sewage is poured into the box body from the mixed liquid inlet, and can collide with the bending plate, so that the flow velocity of the sewage is reduced, and a better oil-water separation effect is obtained. However, since there is an assembly gap between the bottom surface of the end cap and the bottom surface in the case, it is necessary to press the bottom of the bent plate against the bottom surface in the case by the pressing bolt, thereby preventing leakage of the liquid. However, the area of the tank below the bent plate is wasted, resulting in a reduction in the overall volume of the treated sewage in the tank, and the oil-water separator has a slower treatment efficiency for the sewage, and thus the treatment efficiency of the sewage treatment system is also reduced.

Detailed Description

The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.

As shown in fig. 1, 2 and 3, the sewage treatment system comprises an oil-water separator 14, a slag separating tank 15, a kitchen waste adjusting tank 16, a comprehensive adjusting tank 17, a pH adjusting tank 18, a UASB tank 19, an anoxic tank 20, a primary contact oxidation tank 21, a secondary contact oxidation tank 22, a primary sedimentation tank 23, a dephosphorization tank 24, a secondary sedimentation tank 25 and a clean water tank 26 which are sequentially communicated in the sewage conveying direction. The oil-water separator 14 includes a casing 1, an opening 2 is formed on one side of the casing 1, and a stop portion 3 is formed at the bottom of the opening 2, for example, the stop portion 3 and the casing 1 are integrally formed through welding or stamping. Meanwhile, the opening 2 is detachably connected with a cover plate 4, and the opening 2 can be closed through the cover plate 4. Similarly to the prior art, the inner side of the cover plate 4 is provided with a flow baffle 5, the flow baffle 5 is obliquely arranged, and the liquid inlet 6 of the oil-water separator 14 is positioned above the flow baffle 5. Because of the action of the stop part 3, unlike the prior art, a gap for liquid to circulate can be designed between the baffle plate 5 and the bottom surface in the box body 1, that is, the bottom of the baffle plate 5 does not need to be abutted with the bottom surface in the box body 1 to ensure that the liquid is not easy to leak, and the liquid is difficult to leak under the action of the stop part 3. Obviously, the oil-water separator 14 in the disclosure has a larger sewage treatment volume, so that the oil-water separation efficiency of the oil-water separator 14 is greatly improved, and the treatment efficiency of the sewage treatment system is correspondingly improved.

In some embodiments, the cover plate 4 is an integrally formed L-shaped member, such that the cover plate 4 has opposite first and second ends 7, 8. In detail, the first end 7 is intended to engage the stop 3, so as to form a seal against the liquid inside the tank 1 at the stop 3; the second end 8 is used for being connected with the top of the box body 1 so as to form a relatively airtight space for the box body 1 and prevent peculiar smell from being dispersed. Preferably, the stop 3 may have a higher stop height, in which case the level of the liquid may not reach the junction of the first end 7 and the stop 3 and may be discharged from the tank 1. However, in this case, the size of the opening 2 is small, and there may be a case where the baffle 5 is not easily installed through the opening 2.

Preferably, a mortise-tenon structure is arranged between the stop portion 3 and the first end 7, and better sealing performance between the stop portion 3 and the first end 7 is achieved through the mortise-tenon structure, so that even when liquid is not discharged from the box body 1 for the first time and reaches the joint of the stop portion 3 and the first end 7, the situation that the liquid leaks from the joint is not easy to occur. In addition, under the effect of mortise and tenon structure, the peculiar smell in the box 1 also is difficult for following the junction of backstop 3 and first end 7 and dispelling.

For example, the mortise and tenon joint structure comprises a protruding block 11 arranged on the bottom surface of the first end 7 and a groove 12 arranged on the top surface of the blocking portion, and the protruding block 11 and the groove 12 have mutually matched sizes and shapes. In this way, the bump 11 and the groove 12 cooperate to form multiple sealing inflection points, so that the liquid is not easy to leak out.

Preferably, a seal 10 is pressed between the first end 7 and the stop 3. For example, the sealing member 10 is a rubber plate, and the sealing member 10 includes a concave portion and planar portions connected to both sides of the concave portion. When the first end 7 is mounted on the stop portion 3, the protrusion 11 presses the recess portion into the groove 12, and the two flat portions are pressed between the first end 7 and the two end faces of the stop portion 3, so that better sealing performance is formed between the first end 7 and the stop portion 3 by pressing and squeezing the sealing member 10.

In some embodiments, the second end 8 is stacked on the top surface of the case 1, and the second end 8 and the case 1 have overlapping portions when seen in cross section, and the fastener 9 may be configured on the overlapping portions to achieve a sealed and fixed connection of the second end 8 and the case 1. For example, the fastener 9 may be a fastening bolt.

For example, the liquid inlet 6 may be formed at the second end 8, so that the liquid inlet 6 and the baffle 5 have a facing relationship, and the sewage flowing into the tank 1 from the liquid inlet 6 may flow toward the bottom end of the baffle 5 at the top end of the baffle 5, so that the flow rate of the sewage is reduced to the maximum extent.

In some embodiments, the baffle 5 is hinged to the cover plate 4, e.g. the baffle 5 is hinged at the intersection of the first end 7 and the second end 8. Furthermore, an elastic member 13 is connected between the baffle 5 and the first end 7. Therefore, when the cover plate 4 is installed with the box body 1, the flow baffle 5 can be rotated, so that the flow baffle 5 can enter the box body 1 through the opening 2 more easily. That is, in these embodiments, the stopper 3 may have a higher stopper height. When the baffle plate 5 enters the box body 1, the baffle plate 5 can restore an inclined state under the action of the elastic piece 13, so that the flow velocity of sewage from top to bottom can be reduced. For example, the elastic member 13 may preferably be a spring.

The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
