2、i 090204206(The department of chemical and environmental engineering of Wuhan Polytechnic University , Wuhan Hubei 430023)Abstract: in this paper, the design of the object is located in Guiyang city in guizhou red ma

3、ple lake and lake flowers. Based on sediment pollution is serious, as well as sewage and industrial wastewater discharged into lake without deep processing of the rolls, nitrogen and phosphorus concentration is high, lea

4、d to lake and related government authorities in organizing basin's centralized disposal of sewage discharged into the lake body again, investment vigorously construction of sewage treatment plants, to strict supervis

5、ion, into more water could be truncated exogenous from the root. Firstly ,itPut forward by using the method of mechanicaldredge sediment removal of heavy metal elements such as long-term savings. Second application aerat

6、ion in lake body circulation purification system, mainly inhibits the proliferation of microcystis algae release toxic substances. The application of main technology for water purification ecological park, high purificat

7、ion efficiency of purification at the same time also reduces the cost. This design plan to set 250 units undercurrent push flow aerator in red maple lake, in setting 63 undercurrent push flow aerators baihua lake bottom

8、is used for water circulation purification, expect harmful algae removal rate can reach 86%. Ecological park built in on purifying effect is expected: COD removal rate was 26%, and the removal rate of SS was 44%, and the

9、 BOD removal rate was 38%, and TP, TN removal rate is about 20%. In two lakes sediment ShuWa, can be effective in addition to the sediment of heavy metal elements, and to prevent their spread to the upper lake.Key words:
