Wastewater Management in Shanghai

Abstract:

In 1981~2012, the general urban wastewater in Shanghai was between 1.775~2.420 billion tons. Among the urban wastewater, the industrial wastewater emissions before 1988 was more than 1.4 billion tons, then, it was declining to about 649 million tons at 2002, a low value in the past 30 years, less than 50% of the 1980s. The percentage of industrial wastewater in the total urban wastewater discharge is falling from 76.9% in 1981 to under 30% in recent years. The living wastewater emissions increased from 424 million tons in 1981 to 1.697 billion tons in 2012. There is a relationship between the living wastewater increasing and the increase of the permanent residents in Shanghai. At the same time, the living wastewater emissions per capita per day were significantly increased from 100 kg (liter) around 1980s to around 190 kg (liter) in recent years. From 1995, the treatment and management of urban wastewater was continuing to intensify in Shanghai. The ratio of wastewater treating has increasing from 6.35% in 1995 to 85.62% of the total urban wastewater in 2012. Comparing the social-economic development and management of wastewater discharge in Shanghai, it can be seen, the wastewater emissions increasing amplitude was far less than the sizes of population growth and economic growth in the past 30 years
