There are coarse filtration and essence filter two kinds of strainers in disposing polluted water in oil flow process, wherein coarse filtration mainly comprises the strainers such as quartz sand, nut-shell, fibrous nodules; Essence filter comprises PE millipore filter and fine filter.But strainer is in long operational process, owing to being subject to the pollution of sewage, filter effect is caused to be deteriorated, filter leaching material is even made to lose effect, filtrate after simultaneously being polluted can produce a large amount of bacteriums, sewage will be caused in sewage water filtration process to be subject to secondary pollution, injection water quality bacterium to be increased, finally pollutes stratum.
Therefore be necessary to develop a kind of filtrate recoil lotion, oils and the mechanical impurity of filter material surface can be removed, make dirty the loosening of dirt come off under realizing penetrating into dirt, effectively can kill the lower bacterium of dirt simultaneously, prevent growing, to extend the work-ing life of filtrate of the lower bacterium of dirt.
Summary of the invention
In order to solve above-mentioned prior art problem, the object of the present invention is to provide a kind of filtrate to recoil the preparation method of lotion, to recoil lotion with the filtrate preparing a kind of oils and mechanical impurity that effectively can remove filter material surface.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of filtrate recoil lotion, it is characterized in that, the component of being divided by following quality forms: clear water 190 ~ 200, hydrochloric acid 40 ~ 50, tetrahydroglyoxaline 10 ~ 20, dodecyl benzyl dimethyl ammonium chloride 25 ~ 35, Dodecyl trimethyl ammonium chloride 10 ~ 20.
Preferably, described concentration of hydrochloric acid is 8% ~ 12%.
Invention also provides the preparation method of this filtrate recoil lotion, it is characterized in that, comprise the steps:
Step one, divides by quality and takes each component, separated for subsequent use;
Step 2, add that clear water quality divides 70% ~ 80% in mixing tank, and start stirring, mixing speed is 100 ~ 150R/min, stirs 3 ~ 5min;
Step 3, adds hydrochloric acid in mixing tank, starts stirring, and mixing speed is 100 ~ 150R/min, stirs 12 ~ 18min;
Step 3, adds tetrahydroglyoxaline in mixing tank, starts stirring, and mixing speed is 100 ~ 150R/min, stirs 12 ~ 18min;
