Description

The carburetion septic tank

One, technical field: the utility model relates to the sewage treatment unit of a kind of restaurant, hotel, food processing plant, residential building, particularly relates to a kind of carburetion septic tank that is used for the oily(waste)water purifying treatment.

Two, background technology: the various septic tank technology that are widely used in dining room, residential building at present, can only degenerate decomposition to the ight soil in the sewage, foreign material, and the sump oil in the sewage can not effectively be purified, make a large amount of sump oils enter water drain with waste water, bonding easily, be deposited in water drain or sewer line inwall, the outfall sewer footpath is day by day reduced, slowly cause the sewer line total blockage, sewage, sump oil are excessive, contaminate environment, polluted air.Directly enter city planting ductwork if contain the sewage of sump oil, because soaking through sewage, sump oil can form sump oil stone, sump oil stone is as hard as marble, be difficult to fragmentation, and continuous expansion with its volume, time has been grown and also can cause pipe network to stop up, and reduces municipal wastewater pipe network pollution discharge capability, has increased maintenance cost and sewage disposal difficulty.Handle at present because the outfall sewer that oily(waste)water causes stops up, method commonly used is with artificial cooperative mechanical external force dredging pipeline, exhausts the people and drains the treasury, bothersome effort, effect is also bad, because greasy dirt itself is difficult to clean out, and has very strong cementability again, has handled well specifically, do not cross and how long stopped up again, deal with very trouble, also significantly reduced the work-ing life of the sewer line in restaurant, hotel etc., increase extra economical load.

And also do not have at present effect reasonablely can be used for carburetion simultaneously, change the sewage treatment unit that excrement is handled.China utility model patent ZL 98236166.1 (notification number CN2344400Y) have proposed a kind of modified version shunting suction type septic tank, constitute by changing excrement first pond, change excrement second pond and wastewater sedimentation filtering basin, on being located at of fecal sewage import excrement first pond, the sanitary wastewater import is located at the import of wastewater sedimentation filtering basin, wherein change and be provided with sloping plate unit in excrement second pond and reclaim the suction tube that muck is used, form separator channels by relative up and down dividing plate changing between excrement first pond and second pond, in the wastewater sedimentation filtering basin, be provided with anaerobic filter bed.This utility model is convenient to the unified management septic tank, can realize the efficient processing of sewage and the recycling of ight soil, improve water pollution and ground condition, shortcoming is to play the sump oil effect that separates, do not reach the carburetion effect, contain swash plate and anaerobic filter bed in addition on the structure, increased difficulty of construction and cost of manufacture.

Three, utility model content:

The utility model proposes a kind of carburetion septic tank at the prior art deficiency, can effectively sump oil, foreign material, ight soil in the sewage be separated, and makes after the sewage purification to discharge naturally, can not cause fouling, the obstruction of sewer line and sewage disposal pipe network.

The technical scheme that the utility model adopted:

A kind of carburetion septic tank, contain the pond body, be provided with the sewage import at pond body one upper lateral part, be lower than sewage import horizontal plane on body opposite side top, pond and be provided with sewage outlet, be provided with excrement decomposing wall in body bottom surface, pond body bottom, pond is divided into corruption district and resolver, the both sides of the excrement decomposing wall of body bottom surface, pond, be divided into two oil degenerating areas and purify sewage area at the upper end cover internal surface of pond body to having the top of twice suspending oil degenerating wall with the pond body, the body upper end cover respectively is provided with well head in the pond of two oil degenerating area correspondences.

Described carburetion septic tank, the lower surface of first road, the second road oil degenerating wall and the upper end surface of excrement decomposing wall are in same plane, and perhaps the lower surface of first road, the second road oil degenerating wall is lower than the upper surface of excrement decomposing wall.

Described carburetion septic tank, the lower surface of the second road oil degenerating wall is lower than the lower surface of the first road excrement decomposing wall.

Described carburetion septic tank, sewage outlet is connected with drowning well, and drowning well is provided with the water outlet that inserts sewage network, and the well top of falling into water is provided with well head, and each well head is provided with well lid.

Described carburetion septic tank, body bottom surface, pond is provided with the twice excrement decomposing wall, corresponding excrement decomposing wall at pond body upper end cover internal surface to having three road oil degenerating walls, the lower surface of the second road oil degenerating wall is lower than the lower surface of the first road excrement decomposing wall, the lower surface of the 3rd road oil degenerating wall is lower than the lower surface of the second road excrement decomposing wall, and sewage outlet is connected with drowning well, and drowning well is provided with the water outlet that inserts sewage network, corresponding each oil degenerating area of well top and pond body upper end cover that falls into water is provided with well head, and each well head is provided with well lid.

Useful positively effect of the present utility model:

1, the utility model carburetion septic tank by oil degenerating wall, excrement decomposing wall with upper and lower oil degenerating area, sewage purification district and corruption district, the resolver of being divided into respectively of pond body, separation through the two poles of the earth oil degenerating wall, the sewage of discharging is substantially free of greasy dirt and other foreign material, can not cause the obstruction of sewer line and sewage network, sump oil utilizes again in also can be the regularly paid pond for recovering, maintenance-free, easy to use, relieved.

2, the utility model carburetion septic tank is simple in structure, purifying treatment sewage is effective, sump oil, mud can be recycled, it popularizes the work-ing life that will prolong sewer line and sewage network, reduce maintenance, cleaning up cost greatly, reduce labor intensity, reduce urban operating mechanism sewage disposal difficulty.
