Technical field
The utility model relates to field of Environment Protection, specifically refers to a kind of reverse osmosis membrane natural pond liquid concentration systems.
Background technology
In recent years the quantity of China's scale livestock farming and intensive degree improve constantly, and cause the problem of environmental pollution of livestock and poultry feces day by day serious.Meanwhile, biogas engineering produces a large amount of high density natural ponds slag, natural pond liquid, and its process handling problems highlights gradually.Although containing a large amount of nutritive substances such as organic matter, humic acid in natural pond slag, natural pond liquid, be back to farmland and effectively can improve agricultural output, but near often existing, little, the long distance transportation high cost of farmland digestion ability to arrange jobs utilization in not enough, winter etc. utilize the uneven and economy problems of spatial and temporal distributions.Simultaneously compared with chemical fertilizer or organic commercial fertilizer, in the liquid of natural pond, every nutritive element concentration is on the low side, and the enthusiasm that peasant utilizes is not high, limits the feasibility that agricultural is dissolved to a certain extent.
Utility model content
The purpose of this utility model is to provide a kind of reverse osmosis membrane natural pond liquid concentration systems, reaches and makes full use of natural pond liquid to improve the object of natural pond liquid thickening efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of reverse osmosis membrane natural pond liquid concentration systems, comprise natural pond liquid pool, acid bath, first hay tank, secondary filtration tank and pressure pump, described natural pond liquid pool, acid bath are communicated with by conduit with first hay tank respectively, described first hay tank is communicated with secondary filtration tank, pressure pump and reverse osmosis film body successively, described reverse osmosis film body comprises two outlets be communicated with clean solution tank, concentrated liquid pool respectively, and described concentrated liquid pool is communicated with first hay tank by conduit, and between natural pond liquid pool and first hay tank, pre-filter tank is also installed; Also comprise spray header, described spray header is communicated with pond, and described spray header is positioned on described reverse osmosis film body, and described spray header has multiple spurt hole, and described spurt hole is connected with plastic hose.During utility model works, natural pond liquid in the liquid pool of natural pond flows through in pre-filter tank fast, by pre-filter tank, the major diameter solid residue in the liquid of natural pond is removed and got rid of, remaining stoste is then direct enters into first hay tank together with the acid solution in acid bath, mixed solution is formed after stoste and acid solution interact for some time, enter in secondary filtration tank again, finally enter under the pumping of pressure pump in reverse osmosis film body, by the layered shaping of reverse osmosis film body, mixed solution through again filtering is divided into two-way, enter in clean solution tank and concentrated liquid pool respectively, namely the concentrated of natural pond liquid is completed.And when technician detects the strength of fluid in concentration basin, if concentrated concentration compound standard, then direct by discharging to use in concentration basin; When concentrated concentration does not meet standard, then by conduit, the concentrated solution in concentration basin is injected in pre-filter tank, and the magma in the liquid pool of natural pond mixes again, namely carry out enrichment process again, to ensure that concentrated concentration meets the requirements.
Wherein, in the use procedure of reverse osmosis film body, when its constant pressure flux depression 8% ~ 16%, the current in pond begin through spray header and are directly sprayed onto on reverse osmosis film body, the residue be attached on film body is removed in time, to ensure the normal use of film body.Further, the plastic hose that spray header connects, in the moment of current ejection, can utilize the easy deformation behavior of himself to change the injection direction of current, and then the area coverage of current is increased, reach the efficiency improving spray irrigation.
Also comprise liquidometer, described liquidometer is arranged in acid bath.Liquidometer can detect the acid solution liquid level in acid bath in real time, ensures that, in thickening filtration operation, the blending ratio between quantitative acid solution and quantitative stoste is stablized, to realize the maximization of reaction efficiency when both mix.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model is when technician detects the strength of fluid in concentration basin, if concentrated concentration compound standard, then directly to discharge to use by concentration basin; When concentrated concentration does not meet standard, then by conduit, the concentrated solution in concentration basin is injected in pre-filter tank, and the magma in the liquid pool of natural pond mixes again, namely carry out enrichment process again, to ensure that concentrated concentration meets the requirements;
2, liquidometer of the present utility model can detect the acid solution liquid level in acid bath in real time, ensures that, in thickening filtration operation, the blending ratio between quantitative acid solution and quantitative stoste is stablized, to realize the maximization of reaction efficiency when both mix.

Embodiment
Clearly understand for making the purpose of this utility model, technical scheme and advantage, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, exemplary embodiment of the present utility model and explanation thereof are only for explaining the utility model, and conduct is not to restriction of the present utility model.
Embodiment 1
As shown in Figure 1, the present embodiment comprises natural pond liquid pool 1, acid bath 3, first hay tank 5, secondary filtration tank 6 and pressure pump 7, described natural pond liquid pool 1, acid bath 3 are communicated with by conduit with first hay tank 5 respectively, described first hay tank 5 is communicated with secondary filtration tank 6, pressure pump 7 and reverse osmosis film body 8 successively, described reverse osmosis film body 8 comprises two outlets be communicated with clean solution tank 9, concentrated liquid pool 10 respectively, and described concentrated liquid pool 10 is communicated with first hay tank 5 by conduit, and between natural pond liquid pool 1 and first hay tank 5, pre-filter tank 2 is also installed; Also comprise spray header 12, described spray header 12 is communicated with pond 11, and described spray header 12 is positioned on described reverse osmosis film body 8, and described spray header 12 has multiple spurt hole, and described spurt hole is connected with plastic hose.
During work, natural pond liquid in natural pond liquid pool 1 flows through in pre-filter tank 2 fast, by pre-filter tank 2, the major diameter solid residue in the liquid of natural pond is removed and got rid of, remaining stoste is then direct enters into first hay tank 5 together with the acid solution in acid bath 3, mixed solution is formed after stoste and acid solution interact for some time, enter in secondary filtration tank 6 again, finally enter in reverse osmosis film body 8 under the pumping of pressure pump 7, by the layered shaping of reverse osmosis film body 8, mixed solution through again filtering is divided into two-way, enter in clean solution tank 9 and concentrated liquid pool 10 respectively, namely the concentrated of natural pond liquid is completed.And when technician detects the strength of fluid in concentration basin, if concentrated concentration compound standard, then direct by discharging to use in concentration basin; When concentrated concentration does not meet standard, then by conduit, the concentrated solution in concentration basin is injected in pre-filter tank 2, and the magma in natural pond liquid pool 1 mixes again, namely carry out enrichment process again, to ensure that concentrated concentration meets the requirements.
