Abstract
According to the conclusion and suggestions of economize water usages action plan which made by ”The National Land and Water Resource Conference” in 1998, the industrial water reuse ratio regulations will be enforced in the near future, in order to enhance the percentage of utilizing water effectively and increase wastewater reuse ratio. Therefore, using the advance wastewater treatment to treat the effluent from conventional wastewater treatment plant which can provide qualified effluent to meet the industrial wastewater reuse standards. Then, by dual water supply system distribute retreat-effluent to different water supply points. We can gradually reach 65% of industrial water’s reuse ratio in year of 2011.ue to the transformations of Wugu industrial district, the domestics wastewater content 85 % of total wastewater. In order to reduce the environment-loading, we shall not only treat the wastewater, but also consider the effluent’s recycle. Beside, the rainwater is also a precious resource to retain and recycle, it’s a very important issue. Therefore, “material flow analysis” and “box and whisker plot” will be used to study the stability of Wugu industrial district rainwater and wastewater states, and then provide the recycling water for the Wugu industrial district or the different purpose water source for neighborhood.ccording to research, Wugu industrial district wastewater treatment’s effluent can meet all the quality standards. Therefore, by using the advanced wastewater treatment and recycling the effluent will reduce the water consumption 1,849,350 m3 per year. Which mean it can saves the tapwater fee about 30,329,340～35,692,455 NT dollars (without the initial installation cost) and reduces 388,363.5 kgs of CO2 per year.he designed flow rate of Wugu industrial district wastewater treatment was 12,500 CMD. However, the actual operating flow rate is 5,000 CMD, which mean the margin of the capacity can deal with the wastewater from Shinjuang Sub-Center about 6,987 CMD. Therefor, the recycling wastewater not only can provide the Wugu industrial district, but also the cleaning water source of Zhonggang large drainage.
