Abstract
The invention belongs to the technical field of traffic environments, discloses an automotive wastewater treatment method and particularly relates to a method using ozone for purification treatment of C12 fatty alcohol polyoxyethylene ether. The C12 fatty alcohol polyoxyethylene ether is completely decomposed to water and dischargeable carbon dioxide by means of pollutant concentration detection and adjustment of reaction temperatures and pH (potential of hydrogen) values 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 C12 fatty alcohol polyoxyethylene ether 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 in the wastewater from car washer often with carbon 12 (C
12) AEO is principal pollutant.Therefore, for C in the wastewater from car washer
12The processing of AEO 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 AEOs, through detection of contamination concentration, conditioned reaction temperature, pH value make C
12AEO is decomposed into water and the carbonic acid gas that can discharge fully, and calculates C
12AEO 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 AEOs:
1, reaches 3.5mg/L when above at temperature 10 ~ 30
, the ozone content of pH value more than 7.5, in the waste water, according to reaction formula
Ozone can be to C
12AEO carries out oxygenolysis completely, generates water and the carbonic acid gas that can discharge, and has eliminated C
12Reaction such as AEO 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 more than 7.5, and temperature is 10 ~ 30
, determine C in the unit volume
12The molar weight of AEO, C during according to reaction
12The molar relationship ratio of AEO 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 AEO 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 AEO reduces even eliminates the exhaust emission of wastewater from car washer, and passes through C in the wastewater from car washer
12The detection of AEO 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.
Description of drawings
Accompanying drawing 1 is the purifying treatment method principle assumption diagram of a kind of ozone of the present invention to carbon 12 AEOs, 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 ~ 30
, the ozone content of pH value more than 7.5, in the waste water, according to reaction formula
Ozone can be to C
12AEO carries out oxygenolysis completely, 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 original C
12Reaction such as AEO 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 more than 7.5, and temperature is 10 ~ 30
, the C of sewage inlet
12The concentration of AEO is 200mg/L, C
12The relative molecular mass of AEO is 626, can calculate C in one liter of waste water solution
12The quality of AEO is converted into molar weight again and is about 0.0003mol, 1molC
12AEO decomposes the ozone that needs consume 32mol fully, thereby calculates the ozone of required 0.0096mol, and when the ozone input was 4g/min, the ozone amount that calculates reaction in a minute was 0.083 mol, can handle the C of 0.0026mol
12AEO is converted into C
12The quality of AEO is 1.63g, considers solubleness and the reaction efficiency of ozone in water, need be the flow rate control of outlet valve in 8.15L/min;
3, wastewater from car washer detects C in the waste water through proofing unit after filtering
12The concentration of AEO; 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; Adjust the water valve aperture flow is remained in the 8.15L/min, more than 85%, ionic activity thing clearance is more than 90% at the monitoring of the water outlet after processing COD (COD) clearance.
