Existing process for treating waste water for car wash commonly used has: materialization treatment process, electrolytic process, membrane bioreactor, magnetic kind magnetic separation method etc.Wherein electrolytic process need not to add pharmaceutical chemicalss such as oxygenant, flocculation agent, convenient and flexible operation; Document " Li Bin; Li Yanglin. electrochemical process is handled the development [J] of carwash waste water recycling equipment. industrial safety and environmental protection; 2010; 5 (36): 9-10 " literary composition, confirmed that electrochemical method purifies the technical process and the basic parameter of wastewater from car washer equipment for reclaiming, water outlet has reached country and has reused water quality standard.But its equipment is huge, and power consumption is high, and reckons without the pollution that tensio-active agent brought in the automobile waste water; Membrane bioreactor is the efficient water treatment device that development in recent years is got up, and degradation efficiency is high, device compactness, succinct; Document " Han Fei, intact face is magnificent, and Chi Yichao; Tian Binghui is high rich. NACF carrier organism embrane method Treatment of Washing car waste water research [J]. environmental engineering journal, 2010; 4 (4): 751-755 " literary composition, point out at normal temperatures PH=6.5 ~ 7; Flooding quantity is when 30mL/min, and reactor drum reaches optimal operating parameter, and its effluent quality reaches the specified standard of the main water quality of car wash water in " miscellaneous domestic water quality standard " fully.But equipment needs under specific environment, to move, and is subject to the extraneous factor influence, and biomembrane activity has saturated phenomenon, can not work long hours.
Summary of the invention
In order to overcome the deficiency that there are aspects such as residual contamination in art methods; The present invention proposes the purifying treatment method of a kind of ozone to the glycerin fatty acid ester Soxylat A 25-7; Through detection of contamination concentration; Conditioned reaction temperature, pH value; Make the glycerin fatty acid ester Soxylat A 25-7 be decomposed into the water and the carbonic acid gas that can discharge fully, and calculate the glycerin fatty acid ester Soxylat A 25-7 and decompose required ozone amount fully, reach efficient processing pollutent through the ozone flow of regulating control outlet valve aperture and feeding.
The technical solution adopted for the present invention to solve the technical problems: a kind of ozone is characterized in may further comprise the steps to the purifying treatment method of glycerin fatty acid ester Soxylat A 25-7:
1, reaches 3.5mg/L when above at temperature 10 ~ 37
, the ozone content of pH value more than 7.5, in the waste water, according to reaction formula
In the formula:
;
Ozone can carry out oxygenolysis completely to the glycerin fatty acid ester Soxylat A 25-7; Generate water and the carbonic acid gas that can discharge, eliminated of the harm of reaction derived products such as glycerin fatty acid ester Soxylat A 25-7 molecule and ethers thereof, alcohols, lipid, ketone water quality;
2, through detecting Pollutant levels in the waste water; Allotment waste water solution to pH value is more than 7.5; Temperature 10 ~ 37
; Determine the molar weight of glycerin fatty acid ester Soxylat A 25-7 in the unit volume; According to when reaction the glycerin fatty acid ester Soxylat A 25-7 with the molar relationship ratio of ozone, determine the content of the required ozone of reaction;
3, wastewater from car washer filters and is convenient to gas, water blended container after supercharging feeds with ozone, through detecting the concentration of glycerin fatty acid ester Soxylat A 25-7, regulates control outlet valve aperture and ozone amount.
The invention has the beneficial effects as follows: the present invention is through the processing of ozone to tensio-active agent glycerin fatty acid ester Soxylat A 25-7 in the wastewater from car washer; Reduce even eliminate the exhaust emission of wastewater from car washer; And through detection to glycerin fatty acid ester polyethenoxy ether content in the wastewater from car washer; Regulate ozone flow and outlet valve aperture, thereby reach energy-efficient.
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
