摘要:
针对某城市污水厂不同典型工艺设施的恶臭气体产生特性和收集要求，对常规恶臭气体收集方式进行了比较和分析。以污泥脱水间为对象，进行了典型半开放污染源的恶臭气体收集装置设计，该装置由伞形罩体、集气支管和负压引风机组成，在微负压条件下，伞形罩体对气流具有较好的诱导作用，可有效减少气体收集死区，提高收集效率。将该收集装置与生物过滤除臭装置结合，应用于该城市污水厂污泥脱水间恶臭气体的收集和处理，恶臭气体收集和处理量为370 m3/h。结果表明，该收集和处理装置对硫化氢和氨的去除率分别为99.25%和99.41%，达到了较好的收集处理效果。
Abstract:
According to malodorous gas generation characteristics and collection requirements of typical processes facilities in a municipal wastewater treatment plant, the conventional malodorous gas collection modes were compared and analyzed. A typical semi-open pollution source malodorous gas collection device in a sludge dewatering room was designed. The device was composed of an umbrella-shaped cover, an air collecting branch pipe and a negative pressure induced draft fan. Under the condition of slight negative pressure, the umbrella-shaped cover had a better induction effect on the air stream, and effectively reduced the dead zone of the gas collection and improved the collection efficiency. The collection device and biological filtration deodorizer were combined to collect and treat malodorous gas in the sludge dewatering room of the municipal wastewater treatment plant, and the collection and treatment capacity of malodorous gas was 370 m?/h. The removal efficiencies of hydrogen sulfide and ammonia were 99.25% and 99.41%, respectively, indicating that a good collection and treatment performance was achieved.
