Abstract
The invention discloses an automobile wastewater treatment method, belongs to the technical field of traffic environment, and particularly relates to a method of using ozone for purifying carbon-12 sodium alcohol ether sulphate. The method includes that reaction temperature and pH (potential of hydrogen) values are adjusted by detecting pollutant concentration to enable carbon-12 sodium alcohol ether sulphate to be completely decomposed into water, sodium ions, sulfate ions and dischargeable carbon dioxide. The defects of residue pollution and the like in the prior art are overcome, ozone quantity required by complete decomposition of carbon-12 sodium alcohol ether sulphate can be worked out, and high efficiency in treatment of pollutants can be achieved by regulating openness of a water outlet valve and flow of fed ozone.

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 in the wastewater from car washer often with carbon 12 (C
12) polyoxyethylenated alcohol sodium sulfate is principal pollutant.Therefore, for C in the wastewater from car washer
12The processing of polyoxyethylenated alcohol sodium sulfate is essential.
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 carbon 12 polyoxyethylenated alcohol sodium sulfate, through detection of contamination concentration, conditioned reaction temperature, pH value make C
12Polyoxyethylenated alcohol sodium sulfate is decomposed into water, Na fully
+, SO
4 2-With the carbonic acid gas that can discharge, and calculate C
12Polyoxyethylenated alcohol sodium sulfate decomposes required ozone amount fully, reaches the efficient processing to 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 carbon 12 polyoxyethylenated alcohol sodium sulfate:
1, reaches 3.5mg/L when above at temperature 10 ~ 40
, the ozone content of pH value below 7, in the waste water, according to reaction formula
Ozone can be to C
12Polyoxyethylenated alcohol sodium sulfate carries out oxygenolysis completely, generates water, Na
+, SO
4 2-With the carbonic acid gas that can discharge, eliminated C
12Reaction such as polyoxyethylenated alcohol sodium sulfate molecule and ethers thereof, alcohols, ketone derived products is to the harm of water quality;
2, through detecting Pollutant levels in the waste water, allotment waste water solution to pH value is below 7, and temperature is 10 ~ 40
, determine C in the unit volume
12The molar weight of polyoxyethylenated alcohol sodium sulfate, C during according to reaction
12The molar relationship ratio of polyoxyethylenated alcohol sodium sulfate and ozone is determined 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 C
12The concentration of polyoxyethylenated alcohol sodium sulfate is regulated control outlet valve aperture and ozone amount.
The invention has the beneficial effects as follows: the present invention passes through ozone to tensio-active agent C in the wastewater from car washer
12The processing of polyoxyethylenated alcohol sodium sulfate reduces even eliminates the exhaust emission of wastewater from car washer, and passes through C in the wastewater from car washer
12The detection of polyoxyethylenated alcohol sodium sulfate content is regulated ozone flow and outlet valve aperture, thereby is reached energy-efficient.
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
