In the sewage plant design, should meet the following principles: according to the country about environmental protection policy, as well as meet the local national related laws and regulations, norms and standards; The use of advanced and reliable process to ensure that the processed can reach the discharge standards; Guaranteed, efficient and high quality of advanced equipment, high standards and design of automatic control system, so that the daily operation and management; Comprehensive planning, rational layout, the overall coordination, the sewage treatment engineering do not contradict with the surrounding environment, coordinated; Considering environmental, economic and social benefits, on the premise of ensure that water quality standard, try to reduce unnecessary engineering investment and operation management cost; Proper management during the process of sewage treatment, the solid content of sludge in preventing secondary pollution of the environment. So that every design process of the sewage plant can reasonably and reduce the initial investment and area.
In terms of design and calculation, according to the technical specification for oxidation ditch sewage treatment of activated sludge system, the sewage treatment plant process design manual ", "water supply and drainage design manual", "oxidation ditch sewage treatment technology", "urban sewage treatment plant pollutant discharge standard", "indoor drainage design code for structures, elevation, factory district area, found the correct method to calculate, carries on the reasonable design. Computing, and according to the above method of proofreading, ensure the correctness of the design and calculation, to follow-up factory drawings for plane, elevation, structures, so as to achieve all the requirements for sewage design, reasonable and correct creative design are presented.
Key words: Carrousel oxidation ditch Urban sewage Water pollution control
