2、act With the acceleration of industrialization, the output of wastewater is increasing obviously. To get basic control of the aggravating environmental pollution and ecological destruction, we need to take comp

3、rehensive measures to prevent and treat the industrial wastewater pollution. In order to facilitate the comprehensive management of industrial wastewater, manufacture is gradually transforming from decentralization

4、 to centralization .Now, the very popular practice is developing industrial parks, then migrate the industrial enterprises to it .We built public sewage treatment plants in the park, and dispose industrial wastewater

5、from different enterprises centrally after pretreatment to solve the intractable treatment of industrial wastewater and increasingly serious water pollution and water shortage problem.There are different kinds of industr

6、ies in the park, and the wastewater from different industries contains various pollutants and the pollution levels are different. So, before the design of sewage treatment in industrial park, the designer takes the firm

7、size, the company property, the area of the park, the planning requirements, sewage characteristics and water treatment technology into consideration, decided to adopt Sequencing Batch Reactor Activated Sludge Process.

8、The process change the traditional aeration tank, settling tank from the spatial distribution to the distribution of the time, it forms intensive integration structures, and help to achieve a compact layout module, the

9、biggest advantage is saving area. In addition, it reduces the sludge recycle flow rate and it is energy saving. A typical SBR process stops water when sediment, static precipitation can get higher efficiency and better
