Scheme design of the project in accordance with the requirements on environmental protection in the sewage, prepared in accordance with the basis, principles and the actual situation, focusing on in pollution source control, the implementation of cleaner production technology, reduce pollution, reduce the total amount of sewage. In the sources of pollution control based on, the introduction of advanced tanning wastewater treatment technology. In comparison to the detailed scheme based on, select the following process:
The design is pided into five parts: introduction, to determine the process, design, investment estimate and benefit analysis. And eight drawings: coarse grid map, regulation pool figure, the primary settling tank plans, hydrolysis acidification pool figure, CASS biochemical pool chart, flow chart, layout, elevation cloth structure diagram.Through the design, analysis currently high concentration sewage treatment technology and process, design of high concentration sewage treatment process. Drawing process flow diagram, design a water meet the related standard parameters. According to the high concentration sewage water quality index data, consult a standard water data, the design and calculation. Analysis and understanding of the high concentration wastewater treatment process and characteristics, and treatment process, wastewater treatment process. Draw the related construction technology and the layout of effluent meet the parameter requirement of the relevant standards.
Keywords: tanning wastewater; CASS pool; A/O denitrification pool
