| With the development of people's lives, they demand higher quality for the environment and become more and more sensitive to the issue of odor. While odor pollution is growing as modern industrialization and urbanization process in the same time, in particular the development of sewage treatment field. So the odor treatment study has become an urgent subject.Nibuwan WWTP locates in south region of Qingdao economic development zone. The surrounding environment will be found mainly base on coastal tourist, living and commercial housing and human technology, so the demand for environment condition is beginning to rise. Therefore, the implementation of sewage treatment works deodorization project seems particularly important. This thesis studies mephitis treatment scheme of Nibuwan WWTP and analysis the effect after implementation.Firstly, we make sure the odor's source, formation and quantity of Nibuwan WWTP in this design.Secondly, according to the odor's actual conditions in Nibuwan WWTP to choose the right deodorization process. This design adopted the biological deodorization process. The design covered the building and then odors were collected. Then mainly use the biological filtrating pool and adding with soil filtrating methods. Biological deodorization method can deodorization effectively with the merits of advanced and reasonable and without secondary pollution.Thirdly, the design studied deodorization procedure of the biological deodorization system including collecting system, processing system and ejecting system; it works out the influential factors of this process.By s separate study of each part of the system it guarantees this system to work effectively.At last, by monitoring the odors after the process, this project worked quite fine. The odors after being processed were up to the standard and were discharged within the standard. |
