\u6c42\u73af\u5883\u5de5\u7a0b\u4e13\u4e1a\u7ffb\u8bd1The issue of Environmental Engineering curriculum design for the City Economic Development Zone L municipal wastewater treatment plant design - A2O process.
Main task is to select and process design and calculation of structures. During the preliminary design to complete the design specification of a sewage treatment plant in a general layout plan, an elevation map, a flow chart, a map of major equipment. Individual to deal with the construction design of structures, the main plan is to complete the oxidation ditch and profiles. The sewage treatment plant project, with a total size of 240,000 tons / day. The wastewater treatment plant for the sewage treatment process: the sewage from the pumping station to the grit chamber into the aeration tank, secondary sedimentation tank, the final effluent; sludge process as follows: from the secondary sedimentation tank sludge discharged into the first pool enrichment for sludge thickening, and further dehydrated, transported to the landfill.
Sewage treatment plant effluent treatment, the implementation of Integrated Wastewater Discharge Standard (GB8978-1996) 2
Hospital design of wastewater treatment
Abstract: The main hospital discharges from hospital staff and patients of domestic sewage, hospitals Laundry washing sewage, surgical instruments and laboratory analysis of the components, such as flushing sewage, hospitals discharge of sewage every day about 150T. Because the hospital wastewater pollutant concentrations low in basic domestic use of biological exposure to biological oxidation process, against the small amount of hospital waste water treatment characteristics, so choose the form of biological contact acid hydrolysis + aerobic biological treatment as the Programme of biological treatment process. The overall design of sewage treatment station, from 1 m to the grid before the sampling wells after only 1 m, including technology, civil engineering, plumbing, electrical design, and so does not include clean up of segregation, and other channels. .
Key words: hospital wastewater biological contact oxidation acid hydrolysis aerobic biological treatment
Among the preliminary design to finish the design specification, a copy of the sewage treatment plant, a general layout, the flow chart, a major equipment figure. Single processing structures in the working drawing design, mainly is completed the oxidation ditch plan and section.
The sewage treatment plant engineering, the total scale to 24 tons/day. The sewage wastewater treatment process for sewage from inner to sink, sand pool, enter aeration, finally, the second pond water, The process of sludge from the second pond for discharge of sludge concentration, the first enter pool of sludge dewatering, concentration, further to landfill.
After the sewage treatment plant water national integrated wastewater discharge standard (GB8978-1996) secondary standard.
Choose A2O craft, has the good function of phosphorus and nitrogen
