The method includes that reaction temperature and pH (potential of hydrogen) values are adjusted by detecting pollutant concentration to enable isopropyl palmitate to be completely decomposed into water 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 isopropyl palmitate 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.
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 often be principal pollutant in the wastewater from car washer with the Wickenol 111.Therefore, essential for the processing of Wickenol 111 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 Wickenol 111; Through detection of contamination concentration, conditioned reaction temperature, pH value make Wickenol 111 be decomposed into water and the carbonic acid gas that can discharge fully; And calculate Wickenol 111 and decompose required ozone amount fully, reach efficient processing through the ozone flow of regulating control outlet valve aperture and feeding to pollutent.
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 Wickenol 111:
1, reaches 3.5mg/L when above at temperature 10 ~ 40
, the ozone content of pH value below 6.5, in the waste water, according to reaction formula
Ozone can carry out oxygenolysis completely to Wickenol 111, generates water and the carbonic acid gas that can discharge, and has eliminated the harm to water quality of Wickenol 111 molecule and reaction derived products thereof;
2, through detecting Pollutant levels in the waste water; Allotment waste water solution to pH value is below 6.5; Temperature 10 ~ 40
; Determine the molar weight of Wickenol 111 in the unit volume; According to when reaction Wickenol 111 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 Wickenol 111, 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 Wickenol 111 in the wastewater from car washer; Reduce even eliminate the exhaust emission of wastewater from car washer; And through detection to Wickenol 111 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.
Description of drawings
Accompanying drawing 1: a kind of ozone of the present invention is to the purifying treatment method principle assumption diagram of Wickenol 111, among the figure: 1. water-in; 2. strainer; 3. concentration detection apparatus; 4. topping-up pump; 5. ozone inlet mouth; 6. mixing vessel; 7. outlet valve.
Embodiment
With reference to accompanying drawing 1, concrete steps are following:
1, reaches 3.5mg/L when above at temperature 10 ~ 40
, the ozone content of pH value below 6.5, in the waste water, according to reaction formula
Ozone can carry out oxygenolysis completely to Wickenol 111, the oxidation scission of two keys takes place and further break hydrogen bond, generates water and the carbonic acid gas that can discharge, and has eliminated the harm to water quality of original Wickenol 111 molecule and reaction derived products thereof;
2, through detecting Pollutant levels in the waste water; Allotment waste water solution to pH value is below 6.5; Temperature 10 ~ 40
, the concentration of the Wickenol 111 of sewage inlet is 300mg/L, the relative molecular mass of Wickenol 111 is 298.51; Can calculate the quality of Wickenol 111 in one liter of waste water solution; Be converted into molar weight again and be about 0.001mol, the 1mol Wickenol 111 decomposes the ozone that needs consume 19mol fully, thereby calculates the ozone of required 0.019mol; When the ozone input is 4g/min; The ozone amount that calculates reaction in a minute is 0.083 mol, can handle the Wickenol 111 of 0.0044mol, and the quality that is converted into Wickenol 111 is 1.3g; Consider solubleness and the reaction efficiency of ozone in water, need be in 4.3L/min the flow rate control of outlet valve;
3, wastewater from car washer after filtering; Detect the concentration of Wickenol 111 in the waste water through proofing unit; Is that the ozone of 4g/min feed mixing vessel with the hydraulic pressure of 0.4Mpa with air input through topping-up pump, through thorough mixing, adjusts the water valve aperture flow is remained in the 4.3L/min; More than 85%, ionic activity thing clearance is more than 90% at the monitoring of the water outlet after processing COD (COD) clearance.
