日处理2000立方米某印染厂废水处理工艺设计+CAD图纸(2)
The introduction mainly introduced this topic design task, and on into the water, the water quality parameters (such as cod, bod, etc.), water quality, etc., and printing and dyeing wastewater source, characteristics and so on all has carried on the simple introduction.Treatment process selection and instructions are commonly used in printing and dyeing wastewater treatment method, physical method, chemical method and biological method, etc.) are introduced, in addition to illustrate various methods of processing mechanism, will explain the advantages and disadvantages of these methods. After is listed on the commonly used process (such as oxidation ditch, biological contact oxidation pond method, etc.), and from the decision to a technology used in this design, finally decided to adopt the design for the core technology with biological contact oxidation pool. Main structures and computing, just as its name implies is refers to the process of this design is used in the main structures and ancillary structures and calculation, some of these structures include grille, adjusting pool, hydrolysis acidification pool, biological contact oxidation pool, vertical flow sedimentation tank, sludge concentration pool, etc. Layout and elevation layout is refers to in the wastewater treatment plant have to use the rational distribution of structures, it is a comprehensive consideration of the process. Investment estimation is roughly estimate what I design process need to consume money.
Keywords: printing and dyeing wastewater； Process design； Biological contact oxidation.
