Background technique
Volatile organic matter (VOCs) source exhaust gas is extensive, further includes various industry other than the natural sources such as phytovolatilization
The artificial sources such as source, agricultural sources, traffic source and life source.Most of volatilization from organic solvent, as painting dressing automobiles, household are sprayed
Paint, printing coating etc..Wherein, VOCs exhaust gas caused by industrial process has the spies such as discharge amount big, type is more, complicated component
Point.VOCs exhaust gas considerably reduces urban air-quality, seriously threatens human life and health.
Currently, industrial enterprise can be divided into two classes: source control technology and end to the treatment measures of VOCs exhaust gas both at home and abroad
Treatment process.Source control technology is substituted to the raw and auxiliary material for being also easy to produce VOCs exhaust gas, the more environmentally friendly material of use,
The yield of VOCs is reduced with this, the method has certain innovation difficulty, particularly with the choosing difficult to realize of small cost enterprise
The scheme of high-environmental, high-quality raw material is selected, though the method can be reduced the yield of VOCs, the production of VOCs can not be completely inhibited
It is raw;Source control technology further includes the improvement of technique and equipment, uses closed Integral producing apparatus to production area, this is right
For the industrial enterprise for pursuing low cost, booming income, it is also difficult to popularization and application are realized, simultaneously for generated VOCs
Exhaust gas is not also accomplished to administer and be solved.
VOCs exhaust gas end-of-pipe control technology is divided into absorption method and null method again.Absorption method includes absorption method, condensation method and suction
Receipts method, null method include combustion method, oxidizing process, low temperature plasma method and biological treatment.Absorption method and condensation method material consumption it is big,
Energy consumption is high, and absorption process can not be applicable in hydrophobicity VOCs exhaust gas;Although combustion method, oxidizing process and low temperature plasma method energy consumption
It is relatively low, but it is also easy to produce by-product, secondary pollution will cause to environment.It is most commonly used in terms of domestic and international comprehensive condition
VOCs exhaust gas treatment technology is catalysis burning, absorption and biologic treating technique.Because VOCs is many kinds of, complicated component and characteristic not
One, combined treatment technology is mostly used in engineering, and cost consumption is very big.
Summary of the invention
The present invention provides a kind of hydrocarbon solvent VOCs exhaust gas integration processing system and devices, hydrocarbon at present to solve
It is at high cost existing for solvent VOCs exhaust-gas treatment mode, energy consumption is high, applicable surface is narrow or causes secondary pollution problems.
In order to solve the above-mentioned technical problem, the technical scheme is that at the hydrocarbon solvent VOCs exhaust gas integration
Reason system comprising:

Activated sludge absorption system: with activated sludge absorption exhaust gas and dirty water pollutant;
Separating system for water: the exhaust gas further progress gas-water separation for will be overflowed in activated sludge absorption system, point
From sewage backflow to waste gas absorbing system;
Activated carbon adsorption system: it for carrying out activated carbon adsorption processing to the exhaust gas separated in separating system for water, obtains
Clean gas discharge;
Saprobia degeneration system: the water for will come out in activated sludge absorption system carries out the biology of anaerobic and aerobic
Degradation treatment;
Water circulation system: for making the water in system in waste water absorption system, activated sludge absorption system, saprobia drop
It is recycled in solution system.
Integrated processing system provided by the invention incorporates absorption and sorption, biodegrade in one, and water circulation makes
With realizing wastewater zero discharge, solve the various drawbacks of current processing mode.
