Below by taking three groups of combinations as an example, illustrate working principle of the utility model is: first group of stage, volatile organic matter It is introduced in combined volatile organic compound processing system through wind channel, it is abundant via lower layer's air distribution plate volatile organic matter and liquid It contacts, the pollutant in volatile organic matter is adsorbed or aoxidized by liquid medium, and volatile organic matter continues up, by biology Packing layer increases contact area, and the pollutant in volatile organic matter is adsorbed by biologic packing material layer again, and planted by water distributor The spray liquid flowed through is brought water phase into or is aoxidized by the oxidation material in spray liquid.Volatile organic matter using upper layer air distribution plate, Foam is formed under airflow function, is come into full contact with gas phase.

Second group of stage: after volatile organic matter is by first group of stage upper layer air distribution plate, introducing second group through wind channel, Vertically downward, by biologic packing material layer, pollutant is by filling adsorption, and the spray liquid flowed through is brought water phase into or sprayed for air-flow Oxidation material oxidation in liquid.

The third group stage: volatile organic matter introduces third group, air-flow after second group of lower layer's air distribution plate, through wind channel Vertically upward, first pass through lower layer's air distribution plate and be uniformly distributed air-flow, after by taming molding bio-trickling layer in biologic packing material layer, Pollutant in volatile organic matter is degraded by microorganism adsorption and by metabolism, and most the wind channel through upper end draws afterwards It causes outside equipment.

Cyclic water tank is respectively back to spray liquid first group, second group and third group by a circulating pump.

Equipment runs early period, and first group and second group of major function consume certain oxidant as contact oxidation technology, Remove the pollutant in removing exhaust gas；Third group tames the stage as bio-trickling, cultivates microorganism, while using as demisting.

Equipment runs mid-term, and bio-trickling dominant bacteria forms bacterium colony, and can effectively adsorb organic with decomposing volatile Pollutant in object, second group is continued to tame and cultivate dominant bacteria, and first group is still used as the catalytic oxidation stage, and third group is Bio-trickling processing stage.

Equipment runs the later period, and second group and third group biological inoculum maturation then continue to cultivate first group of microorganism, realization is set Standby zero consumption, low cost operation.

Each instruments monitor inlet and outlet VOCs amount in intelligence control system, recirculated water oxidation-reduction potential, recirculated water pH value, The data such as pipeline pressure value and air draft air quantity, each segment process parameter of auto-control, founding mathematical models.

The method for building up of mathematical model: 1, input parameter: air quantity, wind pressure are supervised by the sequence VOCs monitor that VOCs is flowed through VOCs1, VOCs2, VOCs3 and VOCs4 that the data of survey are denoted as respectively, ORP value, pH value.

2, control mode: wind pressure, control control fan frequency converter in standard atmospheric pressure -10Pa, feedback signal；ORP value, mark Quasi-mode controls between 200~400, and feedback signal controls oxidant dosing pump；PH value, mode standard control 7~9 it Between, feedback signal controls soda acid dosing pump.

3, mathematical model: mathematical model is divided into equipment startup stage, debugging stage, stabilization sub stage and normal operating phase four Part.

Equipment startup stage: after booting, equipment automatically records the time, is subject to actual run time, runing time 120 Hour.Electrically operated valve on water distributor is denoted as motor-driven valve 1, motor-driven valve 2, motor-driven valve 3 by the sequence flowed through by VOCs respectively.This rank Section, motor-driven valve 1, motor-driven valve 2, motor-driven valve 3 are all turned on.Built-in domesticated strain is under the supplement of nutrient solution, quickly breeding life It is long.

The debugging stage: after the completion of equipment startup stage, into the equipment debugging stage, it is with (VOCs3-VOCs4)/VOCs3 Standard, this parameter are automatically selected or are manually entered according to VOCs1.This stage, motor-driven valve 1, motor-driven valve 2 are opened, and motor-driven valve 3 is closed, ORP value control simultaneously is between 300~400, guarantee oxidation effectiveness, while ORP value control numerical value receiving (VOCs1-VOCs3)/ VOCs1 control, and this parameter is automatically selected or is manually entered according to VOCs1.

Stabilization sub stage: after reaching stationary value with (VOCs3-VOCs4)/VOCs3, the indication debugging stage terminates, into stabilization Stage.It is subject to (VOCs2-VOCs3)/VOCs2, this parameter is automatically selected or is manually entered according to VOCs1.It is this stage, electronic Valve 1 is opened, and motor-driven valve 2, motor-driven valve 3 are closed, while ORP value control guarantees oxidation effectiveness, while ORP between 200~300 Value control numerical value receives (VOCs1-VOCs2)/VOCs1 control, and this parameter is automatically selected or is manually entered according to VOCs1.

Normal operating phase: after reaching a certain numerical value with (VOCs2-VOCs3)/VOCs2, the indication stabilization sub stage terminates, into Enter normal operating phase.This stage motor-driven valve 1, motor-driven valve 2, motor-driven valve 3 are turned off, and water circulating pump is closed, reservation blower Under wind pressure control, guarantee exhausting effect.

Combined volatile organic compound processing system technique is flexible and changeable, can be right according to volatile organic matter supplied materials situation Each group process section parameter is adjusted, flexible combination, to adapt to wider operating condition, it is ensured that TREATMENT OF VOCs effect.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the those of ordinary skill in field, various modifications and changes may be made to the present invention；It is all the utility model spirit and Within principle, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
