In recent years, environmental problem more and more causes the attention of people, and atmosphere pollution, water pollution, soil pollution, noise pollution, vibration, land subsidence, odor pollution are considered to seven kinds, world today typical environment public hazards.Wherein, odor pollution problem, is more and more subject to people's attention, and has become flagrant problem in environmental problem.Sewage treatment plant is one of important sources of foul waste gas.Along with the sewage disposal cause of China effectively develops rapidly, sewage treatment plant's quantity obviously increases, and can greatly increase from now on, and the generation of foul waste gas is through the overall process of sewage disposal, the odorant produced not only makes people feel to detest unbearably, be mentally affected, and many components are poisonous and harmful or even extremely toxic substance, directly threaten the health even life of people.
In the waste gas that sewage treatment plant produces, main component is hydrogen sulfide, ammonia, mercaptan, thiophene, amine, acid amides, indoles, alkane, alkene, alkynes, aromatic hydrocarbon, alcohol, aldehyde, ketone and organic acid, wherein the amount of ammonia is maximum, next is hydrogen sulfide, due to foul waste gas complicated component, treatment effect requires very high, so utilize single treatment process to be difficult to reach the treatment effect of engine request.Therefore, carry out efficiently for the waste gas produced in sewage disposal process, be comprehensively treated as the subject matter faced at present.Based on this problem, study that a kind for the treatment of effect is good, sewage treatment plant's exhaust treatment system of efficient energy-saving, just become the problem that insider needs solution badly.
Utility model content
The purpose of this utility model is according to the problems referred to above, provides a kind of a kind of sewage treatment plant exhaust treatment system solved the problem.
The technical solution of the utility model is: a kind of sewage treatment plant exhaust treatment system, it is characterized in that: comprise absorption tower, demister, physical absorption device, catalyst oxidation reactor, tubular heat exchanger, aeration tank, first blower fan, second blower fan, described absorption tower sidewall is provided with exhaust gas entrance, gas outlet, top, described absorption tower connects described physical absorption device by described demister, gas in described physical absorption device after absorption enters described catalyst oxidation reactor through pipeline after desorption, the tail gas gas outlet of described catalyst oxidation reactor connects described tubular heat exchanger, the air that described first blower fan produces carries out exchange heat through described tubular heat exchanger with from described catalyst oxidation reactor offgas outlet gas out, and enter after obtaining heat in described physical absorption device to absorption gas carry out desorption, the air produced through described tubular heat exchanger rear portion and described first blower fan from described catalyst oxidation reactor offgas outlet gas out converges, another part is emptying, described aeration tank is not entered by the gas adsorbed through described second blower fan after described physical absorption device, emptying after aerated reaction.
Further, described physical absorption device is swinging adsorbent equipment.
Further, waste liquid outlet is provided with bottom described absorption tower.
Further, the adsorbent in described physical absorption device is any one in the fine based active carbon fiber of polypropylene, silica gel, zeolite molecular sieve, aluminium oxide.
Further, the absorbing liquid adopted in described absorption tower is liquor natrii hypochloritis.
The beneficial effects of the utility model are:
The utility model can remove portion ammonia and hydrogen sulfide by absorption tower, the catalyzed reaction of catalyst oxidation reactor is entered by desorption after physical absorption device absorbed portion foul gas, the gas not being physically adsorbed device absorption passes into aeration tank, makes organic and hydrogen sulfide removal rate to reach 99.6%; The gas that catalyst oxidation reactor exit gas can produce with the first blower fan carries out exchange heat by tubular heat exchanger, has saved energy, has been conducive to sustainable development.
