Abstract

The utility model discloses a hydraulic methane septic tank, which comprises three stage septic tanks, and the three stage septic tanks are connected through through-holes (6), wherein a cushioning well (1) is arranged before the first-stage septic tank (9), and discharge pipes (2) which are communicated to the externals of the tanks are installed in the first-stage septic tank (9) and the second-stage septic tank (8), the tops of the tanks are provided with sealed pyramid air storing chambers (3), and are provided with gas transmission pipelines (4), and a drain outlet (5) of the third-stageseptic tank (5) is connected with a city sewage pipe network. The methane septic tank has simple structure and less investment cost, after adopting design of the hydraulic type septic tank, not onlymethane and highly-effective and good-quality organic manure can be obtained, but also various harmful germs and parasitic ovum can be killed, and hygienic and clear environment is kept.

Description

The hydraulic type miasma septic tank

Technical field

The utility model relates to a kind of septic tank, is specifically related to a kind of hydraulic type miasma septic tank.

Background technology

In recent years, China's rural methane facilities development puts more effort, development is very fast, biogas technology is mature on the whole, by development biogas, the energy of cleaning both can be provided, realized the efficient utilization of resources such as human and animal excreta, wastes of crops again, when solving the human and animal excreta pollution, also reduced the amount of application of agriculture inputs such as agricultural chemicals, chemical fertilizer effectively, reduced the agricultural pollution face, improved the organic content of ploughing, promote the development of the ecological agriculture, Organic farming, improved agricultural product quality greatly, reached the purpose of cost-saving synergistic.

Present septic tank is generally three grades of formula septic tanks, make ight soil and sewage by gravity nature natural separation, sewage is discharged by blow-off line or to allow it be penetrated into underground, ight soil then continues to stay in the first step or the second stage septic tank, allows its spontaneous fermentation, digestion, because substantially all blow-by of septic tank of design at present, run into and rain heavily, tend to cause ight soil, sewage crossing current even refluence, mosquito, fly etc. multiplies, breeds under this environment easily, has had a strong impact on environmental health.

The utility model content

The purpose of this utility model is to provide a kind of hydraulic type miasma septic tank at the deficiencies in the prior art.

The utility model is the technical scheme that its purpose of solution is adopted:

A kind of hydraulic type miasma septic tank, form by three grades of septic tanks, adopt through hole to connect between three grades of septic tanks, the buffering well that is connected with first step septic tank is set before first step septic tank, the sewage of effluent sewerage pipe enters first step septic tank after entering the buffering well again, make the buffering well play buffering and plugging action, avoid septic tank directly to communicate with the external world; In the first step, second stage septic tank, the vent pipe that leads to outside the pond is installed near the pool wall place of bottom, pond, be used to discharge natural pond liquid and natural pond slag, the top in pond is the pyramid gas dome of sealing, and gas pipe line is set, and the biogas that internal cause fermentation in pond is produced is outwards exported; Third stage septic tank is connected with municipal sewage pipe network, sewage is by fermentation entered municipal sewage pipe network, the absolute altitude of the sewage draining exit of third stage septic tank is lower than the absolute altitude of water drain blowdown outlet, but be higher than the height that the buffering well is discharged to first step septic tank, to keep septic tank to be in the water seal state all the time, guarantee that the biogas that is produced can only upwards enter the biogas gas dome.

The utility model is simple in structure, and cost of investment is few, adopts the design of hydraulic type septic tank, can not only obtain biogas, obtains the high-efficiency high-quality organic fertilizer, can also kill various deleterious germs and parasitic ovum, keeps the environment clean.

Description of drawings

Fig. 1 is a cross-sectional view of the present utility model.

Among the figure: 1, buffering well; 2, vent pipe; 3, gas dome; 4, gas pipe line; 5, sewage draining exit; 6, through hole; 7, third stage septic tank; 8, second stage septic tank; 9, first step septic tank.

Embodiment

In the structure shown in the figure, the utility model is made up of three grades of septic tanks, adopt through hole 6 to connect between three grades of septic tanks, the buffering well 1 that is connected with first step septic tank is set before first step septic tank 9, the sewage of effluent sewerage pipe enters first step septic tank after entering the buffering well again, make the buffering well play buffering and plugging action, avoid septic tank directly to communicate with the external world; In first step septic tank 9, second stage septic tank 8, the vent pipe 2 that leads to outside the pond is installed near the pool wall place of bottom, pond, be used to discharge natural pond liquid and natural pond slag, the top in pond is the pyramid gas dome 3 of sealing, and gas pipe line 4 is set, and the biogas that internal cause fermentation in pond is produced is outwards exported; The sewage draining exit 5 of third stage septic tank is connected with municipal sewage pipe network, and by fermentation sewage is entered municipal sewage pipe network.

The absolute altitude of the sewage draining exit of described third stage septic tank is lower than the absolute altitude of water drain blowdown outlet, but be higher than the height that the buffering well is discharged to first step septic tank, to keep septic tank to be in the water seal state all the time, guarantee that the biogas that is produced can only upwards enter biogas gas dome 3.

Claims
