离子-生物除臭技术在全地埋式城市污水处理厂的应用

The Application of Ion-Biological Deodorization Technology in Underground Municipal Sewage Treatment Plant

临沂青龙河净水厂位于市区中心,该厂产生臭气的主要部位为污水预处理、生物和污泥处理段。其中,预处理、污泥处理段产生的臭气浓度较高,其采用离子和生物相结合的除臭方式;生物段产生的臭气浓度较低,其采用生物除臭方式。该厂运行三年来,经监测,外排废气达到相关标准。经核算,该厂每处理1 m~3污水,除臭系统的直接运行成本为0.05元。

Linyi Qinglonghe Wastewater Treatment Plant is located in the center of the urban area,the main parts of the plant that produce odor are sewage pretreatment,biological and sludge treatment sections.Among them,the pretreatment and sludge treatment sections produce higher odor concentrations,which use a combination of ion and biological deodorization methods;the biological sections produce lower odor concentrations,which use biological deodorization methods.The plant has been in operation for three years,and after monitoring,the external exhaust gas has reached relevant standards.According to calculations,whenever the plant treats 1 m3 of sewage,the direct operating cost of the deodorization system is 0.05 yuan.
