日处理4.5万吨地区城市生活污水SBR工艺设计(2)
The paper design principles are as follows: (1) In order to enable employees of raw daily life can easily position the sewage treatment plant in the treatment zone should seek a reasonable and living areas should be separated as far apart; (2) treatment structures Press Process flow arrangement at the same time, should make full use of the terrain; (3) the distance between the structure and the structure should satisfy the laying of pipes, as well as when to meet the maintenance, personnel and vehicles to enter; (4) Since the presence of accidents and treatment plants maintenance, so beyond the pipeline is essential to the existence of the process; (5) the sludge treatment area will produce odor, blower room will generate noise, their position should be reasonable arrangement to avoid or reduce the impact on surrounding residents. (6) provided on the outside of each structure safe passage to facilitate the staff view, meet the needs of goods transportation and daily operations management.
