The sodium diethylhexyl sulfosuccinate is completely decomposed to water, Na+, SO32- and dischargeable carbon dioxide by means of pollutant concentration detection and reaction temperature adjustment so that the shortages of residual pollution and the like of existing technical methods are overcome, and efficient treatment of pollutants can be achieved by computing the ozone amount required by complete decomposition of the sodium diethylhexyl sulfosuccinate and adjusting and controlling openness of a water outlet valve and ozone feeding flow rate.
Description
Technical field
The present invention relates to a kind of automobile method of wastewater treatment, particularly free of contamination high-efficient treatment method belongs to the traffic environment technical field.
Background technology
In recent years; Along with fast development of Chinese economy; The appearance of a series of stimulation automobile consumption policies of country, the quantity of motor vehicle is how much formulas growths, the also fast development of carwash industry of arising at the historic moment in the street; By consequent automobile Cleaning Wastewater often enters sewer line, street without any processing, pollute in the flowers and plants, and be principal pollutant often in the wastewater from car washer with succsinic acid di-sec-octyl sodium sulfonate.Therefore, essential for the processing of succsinic acid di-sec-octyl sodium sulfonate in the wastewater from car washer.
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 succsinic acid di-sec-octyl sodium sulfonate; Through detection of contamination concentration, the conditioned reaction temperature makes succsinic acid di-sec-octyl sodium sulfonate be decomposed into water, Na fully
+, SO
3 2-With the carbonic acid gas that can discharge, and calculate succsinic acid di-sec-octyl sodium sulfonate 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 succsinic acid di-sec-octyl sodium sulfonate:
1, the ozone content in temperature 10 ~ 40
waste water reaches 3.5mg/L when above, according to reaction formula
Ozone can carry out oxygenolysis completely to succsinic acid di-sec-octyl sodium sulfonate, generates water, Na
+, SO
3 2-With the carbonic acid gas that can discharge, eliminated the harm of succsinic acid di-sec-octyl sodium sulfonate molecule and reaction derived products thereof to water quality;
2, through detecting Pollutant levels in the waste water; Temperature be 10 ~ 40
time; Determine the molar weight of succsinic acid di-sec-octyl sodium sulfonate in the unit volume; According to when reaction succsinic acid di-sec-octyl sodium sulfonate 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 succsinic acid di-sec-octyl sodium sulfonate, 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 succsinic acid di-sec-octyl sodium sulfonate in the wastewater from car washer; Reduce even eliminate the exhaust emission of wastewater from car washer; And through detection to succsinic acid di-sec-octyl sodium sulfonate 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.
