1 particle pollution prevention measures of dust: gravity dust collector, inertial separator, centrifugal dust collector: wet dedusting cyclone water film scrubber, self-excited spray scrubber, foam dust collector filtration dust: bag filter, particle filter, electrostatic dust precipitator: dry, wet electric dust collector

2 gaseous pollutant control measures is the main physical and chemical method: absorption method: physical absorption, chemical absorption ( according to the different solubilities )

Adsorption method: porous solid sorbent, such as activated carbon, zeolite, coke, silica gel, molecular sieve condensation method: according to the different catalytic conversion method and saturated vapor pressure: method of biological purification catalytic oxidation, catalytic reduction: biological absorption method, biological filtration combustion method: direct combustion method, burning method, catalytic combustion method, membrane separation method 3 atmospheric pollution comprehensive prevention and control measures of overall planning, rational layout: the improvement of energy structure dominated by coal gas, liquefied petroleum gas, electricity, solar energy, wind energy, improve energy utilization efficiency of central heating of cleaner production to strengthen the green administrative supervision, supervision according to law 4 of total quantity control of air pollution in the atmospheric environment capacity : for a certain area, according to the the natural purification capacity of the pollution source, the layout and structure of certain conditions, to achieve environmental goals, the maximum air pollutant discharge permit.

Total control: control and adjusts the amount of pollutants in a region of the atmosphere pollution sources discharged, so as not to exceed the area of environmental capacity, total emissions that constraint the area method, called the total volume control method.

Technical process: preparation work mode check and forecast of cutting model cut best scheme is given to develop conventional monitoring system
