Description
Technical field
The utility model relates to waste water control device field, is specifically related to a kind of rubbish percolation liquid membrane system cleaning device.
Background technology
City garbage percolate is a difficult problem in waste water control field.The city garbage percolate generation is big, and water quality is complicated, has following characteristics:
(1) organic concentration is high: the COD in the percolate
Cr, BOD
5Concentration can reach several ten thousand mg/l;
(2 ammonia-nitrogen contents are high: the ammonia nitrogen concentration content of percolate is higher, generally about 2000mg/l, have in addition up to more than the 3000mg/l, cause the C/N in the percolate out of proportion, can reduce the effect of biological treatment;
(3) nutrient is out of proportion: phosphorus content is very little in the percolate, and particularly soluble phosphate concentration is lower.For biochemical treatment, the appropriate nutrition element ratio is BOD in the sewage
5: N: P=100: 5: 1, and BOD in the general garbage leachate
5The ratio of/TP is relatively large, differs bigger with the required phosphorus element content of growth of microorganism, therefore in oozing the processing of drop liquid, often lacks P elements, needs extra replenishing;
(4) content of beary metal is high: generally contain more than 10 kind of metal ion in the percolate, wherein heavy metal mainly contains: cadmium (Cd), nickel (Ni), zinc (Zn), copper (Cu), chromium (Cr) and lead (Pb) etc.Microorganism is limited to the removal ability of heavy metal, must adopt the method for other physics, chemistry could effectively solve the high problem of content of beary metal.
At present; Above characteristics to percolate; Accomplish qualified discharge, method commonly used is first with wherein a large amount of COD, the ammonia nitrogen removals of biochemical process general, carries out advanced treating through means such as membrane treatment process, advanced oxidations then; Further remove wherein COD, ammonia nitrogen, the film system can also remove heavy metal ion in a large number simultaneously.
Commonly used to the film system ultrafiltration, nanofiltration, counter-infiltration are arranged because the characteristics of self decision, nanofiltration and counter-infiltration can shared one group of film purging systems; But because nanofiltration and reverse osmosis membrane assembled arrangement mode is different; Cause nanofiltration also different with the flow of the required rinse water of counter-infiltration, if can not solve this difficult problem, then every mantle all needs to be equipped with separately purging system; Promptly increase cost of equipment, increase floor space again.
The utility model content
To the needs of defective that exists in the prior art and practical application, the purpose of the utility model is to provide a kind of rubbish percolation liquid membrane system cleaning device, through this device solves many mantles water yield demand different problems when cleaning, reduce cost.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of rubbish percolation liquid membrane system cleaning device; Comprise and clean water tank, flushing water pump and detergent line; Flushing water pump is communicated with the bottom of cleaning water tank through detergent line; Detergent line comprises inlet pipeline and return line, and inlet pipeline is connected with flushing water pump, and inlet pipeline is provided with first valve and flowmeter; One end of return line is connected with the rinse water delivery side of pump, and the other end is back to the bottom of cleaning water tank, and return line is provided with second valve.
Further, aforesaid a kind of rubbish percolation liquid membrane system cleaning device, said return line are got into by the top of cleaning water tank and clean water tank, and the outlet of return line is positioned at the bottom of cleaning water tank.
Further, aforesaid a kind of rubbish percolation liquid membrane system cleaning device also is provided with Pressure gauge in the said detergent line.
The beneficial effect of the utility model is:
1) realized the cleaning model of " drag many ";
The cleaning device of the utility model adds a return line at exit of pump, respectively return line and cleaning inlet pipeline is controlled through valve and flowmeter, realizes different adjustings of cleaning the water yields.For the nanofiltration under the different permutation and combination methods, counter-infiltration system,, can perfectly realize the cleaning model of " holder is many " through the different cleaning flow of inlet water of control control.
2) cost of reducing investment outlay, easy to use.
The return line of this cleaning device is backwater in the water tank middle and lower part; Can satisfy the needs that water tank stirs, when soup is cleaned in preparation, open the water return pipeline valve and close cleaning inlet pipe road valve; Just can be used as agitating function uses; The expense of mixer is purchased in saving, has saved cost of investment greatly, and use is extremely convenient.
Description of drawings
Fig. 1 is the structural representation of a kind of rubbish percolation liquid membrane system cleaning device of the utility model.
The specific embodiment
Below in conjunction with the Figure of description and the specific embodiment the utility model is done further detailed description.
In existing garbage filter liquid processing device; Different film systems is because the difference of assembled arrangement mode, so the required cleaning water yield is different when cleaning, every mantle system all needs to be equipped with purging system separately and the cost of equipment that causes is high; Increase the difficult problem of floor space again; The utility model is whole to be a kind of rubbish percolation liquid membrane system cleaning device that proposes to the problems referred to above, realizes the cleaning model of " holder is many " through this device, has saved cost of investment greatly.
Fig. 1 shows the structural representation of a kind of rubbish percolation liquid membrane system cleaning device of the utility model; By finding out among the figure; This device is mainly formed by cleaning water tank 1, flushing water pump 2 and detergent line three parts, and flushing water pump 2 is communicated with the bottom of cleaning water tank through detergent line, and detergent line includes inlet pipeline and return line 3; 4 controls of first valve are set on the inlet pipeline opens and flow; 5 controls of second valve are set on the return line 3 open and flow, inlet pipeline also is provided with flowmeter 6, and return line 3 is got into by the top of cleaning water tank 1 and cleans water tank 1; The outlet of return line 3 is positioned at the bottom of cleaning water tank 1; Cooperation through first valve 4 and second valve 5 is controlled the required different cleaning flows of different film systems with the registration of flowmeter 6, and unnecessary soup is back to the bottom of cleaning water tank through return line by the top of cleaning water tank, plays stirring action.In detergent line, also be provided with Pressure gauge 7, the hydraulic pressure of cleaning device is controlled in real time.
At the cleaning device that uses the utility model,, earlier first valve 4 is closed in the stage of making up a prescription; Second valve 5 is opened, and opens flushing water pump 2 then, and soup is circulated to again through reflux line and cleans water tank 3 bottoms; Play good stirring action, make soup more even; At wash phase, open first valve 4 and second valve 5, and regulate its open degree; Through the registration of flowmeter 6, be adjusted to the cleaning flow of film system-computed gained, stable operation then; In the process; Still can there be little stirring action, the soup in cleaning the back soup that refluxes in the film system and cleaning water tank is fully mixed, reach the liquor strength of homogeneous.
The utility model has solved in the same set of percolate treating process, two covers is arranged or overlap nanofiltration, counter-infiltration system more, and the cleaning flow that produces because of the difference of membrane module permutation and combination method does not wait, and the needs that cause overlap the problem of purging system more.Not only save the investment operation cost, saved floor space, also made whole technology oversimplify easy operating.
