城市排水设施中恶臭源的产生及其治理对策的研究

城市排水设施中恶臭的产生有其必然性和极大的危害性,恶臭源的分布也具有一定的规律性。城市排水设施中产生的恶臭污染物主要是硫化氢气体。目前可以从恶臭源的抑制和收集处理两方面制定恶臭防治对策,采取向排水管道或窨井中加药或充氧等,抑制恶臭的产生;在污水处理厂或排水泵站中采用恶臭源封闭并用吸附法、氧化法和生物法集中除臭处理,均可获得较好的效果。

On Generation of Source of Foul Smell in Urban Drainage Facilities and the Control Measures

The generation of foul smell in urban drainage facilities is inevitable and very harmful,and the distribution of foul smell source is of certain regulation.Mainly the foul smell is composed of the gas of hydrogen sulfide.Control measures for foul smell are made on two sides,i.e.inhibition or collection and treatment,for which both are of quite good effect.To inhibit the generating of foul smell,chemical feeding or oxygenating is made in drainage pipe or manholes,while to collect and treat the foul smell,the sealing of source of foul smell as well as theAbs tracts concentrated treatment of adsorption process,oxygenation and biology process are carried out in sewage treatment plants and drainage pumping stations.
