Abstract

The invention provides a method for conducting deacidification, dedusting, demisting, desulfurization, denitrification and deodorization on smoke through the cooperation of wet static and a biological method. The smoke firstly enters a wet dust collector (landfill leachate, activated sludge and other waste liquid are adopted as a washing medium, alkaline matter is added, and the washing medium is kept alkaline), rough particulate matter and acid are removed, temperature is reduced, humidity is increased, and an organic carbon source (coming from bad smells generated by waste liquid volatilization) is added; then the smoke enters a wet electric dust collector, and fine particulate matter (containing heavy metals and dioxin) and water mist are removed; the smoke enters a biological spray washing tower (activated sludge can be used as a washing medium), remaining sulfur oxide, nitric oxide and bad smells are removed under the effect of microorganisms (needing the organic carbon source), and the smoke can reach the standard and can be exhausted.

Description

A kind of wet electrostatic adds bioanalysis flue gas deacidification dedusting demist desulphurization denitration deodorizing method
Technical field
The invention belongs to atmosphere polluting controling technology field.
Background technology
Flue gas mainly from the burning of coal and the solid waste such as rubbish, mud, if process bad, will pollute air.The fume treatment technology of current use mainly contains wet desulphurization, semidry method deacidification, dry electric precipitation, charcoal absorption heavy metal and dioxin, bag-type dusting, SNCR denitration etc., these technology all also exist the problems such as investment is large, operating cost is high, discharge standard is high not, cause some areas atmosphere pollution serious.
Summary of the invention
In order to solve existing fume treatment technology, the present invention is based on the treatment of wastes with processes of wastes against one another, the theory of the comprehensive regulation proposes new flue gas processing method, its step is as follows:
The first step: flue gas enters wet scrubber and (adopts the waste liquid such as percolate, activated sludge as washing medium, and add alkaline matter make its keep alkalescence), in order to remove coarseparticulate, acid and reduce temperature, increase humidity, add organic carbon source (from waste liquid volatilize foul smell);
Second step: flue gas enters wet electrical dust precipitator, and (be usually called for short WESP, it exports granular material discharged concentration and can be controlled in 10mg/m 3below, if desired, 5mg/m is can be controlled in 3below, close to zero-emission), in order to remove fine particle (containing heavy metal and dioxin) and water smoke;
3rd step: flue gas enters biological spray scrubber (Useful active mud is as washing medium), remaining oxysulfide, nitrogen oxide and foul smell are removed under the effect (needing organic carbon source) of microorganism, and flue gas gets final product qualified discharge.
The advantage of this method is: running resistance is little; Active carbon, ammonia need not be added; The treatment of wastes with processes of wastes against one another, Mist heat recovering makes waste liquid temperature raise, and is conducive to its subsequent treatment; Stricter discharge standard can be met.
Detailed description of the invention
In one embodiment of the invention, method of the present invention is: flue gas is introduced into water dust scrubber and (adopts the activated sludge of sewage treatment plant's generation as washing medium, and add lime make its keep alkalescence), then wet electrical dust precipitator is entered, enter biological spray scrubber (with activated sludge as washing medium) again, out get final product qualified discharge afterwards.
