Description

The sedimentary adjustive pool of livestock and poultry cultivation sewage pre-treatment

Technical field

The utility model relate to a kind of with sedimentation with isolating device in the suspended solid particles from liquid, the sedimentary adjustive pool of particularly a kind of livestock and poultry cultivation sewage pre-treatment.

Technical background

In the prior art, the sewage disposal of livestock and poultry cultivation generally need be passed through pre-treatment, anaerobic treatment and follow-up purifying treatment, the sewage of livestock and poultry cultivation is through the sandstone of settling pit precipitation larger particles in pre-treatment, and then in sedimentary adjustive pool precipitation livestock and poultry sewage remaining solids, sedimentary adjustive pool in pre-treatment comprises several pond bodies side by side, the pond body of one end has water-in, the pond body of the other end has water outlet, the bottom of each pond body is taper, at the bottom of the pond, be extended with the mud scum pipe from the top of taper, scum pipe runs through the pond body sidewall, has several water pipes between the adjacent two pond body sidewalls, the adjacent two pond bodies of this cross current.Sewage after settling pit is handled flows into by water-in in first pond body, at the bottom of solid sediment in this pond body in the sewage is deposited in the pond, the mud scum pipe of the deadweight that utilizes solid sediment at the bottom of the pond discharged, intravital sewage in pond and unprecipitated solids flow in the body of next pond by the water pipe between the two pond bodies, in this pond body, there is the part solids precipitated again, like this until last pond body, sewage is after treatment just discharged from the saliva that goes out of last pond body, enters next sewage disposal operation.But such sedimentary adjustive pool has only precipitated the solid sediment in the sewage, and floating matter is not processed on the sewage, also needs other sewage disposal operation to come floating matter is handled, the sewage treatment process more complicated; And the water outlet aquifer yield of this sedimentary adjustive pool is an isostatic, and therefore, when the water inlet flooding quantity was big, water outlet then might draining in time and cause sewage to overflow from pond body top, causes a processing field environmental pollution.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of and floating matter in the sewage can be removed simultaneously during solid sediment in precipitation sewage, and has the sedimentary adjustive pool of the livestock and poultry cultivation sewage pre-treatment that adjusts water yield function automatically.

The utility model is realized by following approach.

The sedimentary adjustive pool of livestock and poultry cultivation sewage pre-treatment, comprise several pond bodies side by side, the pond body of one end has water-in, the pond body of the other end has rising pipe, rising pipe runs through the sidewall of pond body, the bottom of each pond body is taper, at the bottom of the pond, be extended with the mud scum pipe from the top of taper, scum pipe runs through the adjacent sidewall of sidewall that links to each other with two pond bodies, have several water pipes between the adjacent two pond body sidewalls, the adjacent two pond bodies of this cross current, its structural feature is: the top of another sidewall that the sidewall with scum pipe is installed of pond body is relative is a kind of scarp, it is higher and lower near the external side in pond near the intravital side in pond, the rising pipe of pond body has first feed-water end and second feed-water end, first feed-water end and second feed-water end all are positioned at the inboard of pond body, and first feed-water end is positioned at the below of pond body sidewall, and second feed-water end is positioned at the top of pond body sidewall.

Like this, the scum silica frost of sewage is discharged from the scarp of pool side in the settling tank, and settled mud utilizes concept of differential water pressures, discharges automatically by the mud scum pipe, thereby the floating matter in the sewage can be removed simultaneously during solid sediment in precipitation sewage.And, the water outlet of sedimentary adjustive pool is provided with two feed-water ends, a below that is positioned at the pond body sidewall, one is positioned at the top, when sedimentary adjustive pool water-in flooding quantity more after a little while, wastewater level is the below that is positioned at second feed-water end in the body of pond, and sedimentary adjustive pool only carries out draining by first feed-water end of rising pipe; When wastewater level in the body of pond is when being positioned at the top of second feed-water end, sedimentary adjustive pool then passes through two feed-water ends drainings simultaneously of rising pipe, thereby guarantee the flooding quantity of sedimentary adjustive pool and go out hydrologic(al) budget, can make concentrated, intermittent water inlet become balanced continuity water outlet, balance hydraulic load.

Structure of the present utility model can be specially:

Be used to remove the scarp of the scum silica frost of sewage, highly for being higher than top water-level 15～20mm in the body of pond, scarp and horizontal angle are 35 °～50 ° for it.

Like this, the scum silica frost that swims on the sewage water surface is discharged from the scarp.

First feed-water end of the rising pipe of sedimentary adjustive pool and the height of second feed-water end are respectively:

Below first feed-water end and the distance between the sidewall bottom be 1000mm～400mm.

Above second feed-water end and the distance between the sidewall top be 200mm～250mm.

The height of first feed-water end and second feed-water end can be determined according to the specific design specification of sedimentary adjustive pool.

In sum, the utility model has following advantage compared to prior art: utilize sedimentary adjustive pool to discharge the sink-float slag simultaneously, reduce the organic concentration of sewage, two feed-water ends of rising pipe can make, and concentrated, intermittent water inlet becomes equilibrium, continuity water outlet, the balance hydraulic load has the balanced effect of regulating.
