Prediction of Wastewater Emission in China

Article Preview

Abstract:

A model to predict the wastewater emission in China was established with comprehensive factor analysis, combining the ARMA and OLS methods. Applied the model, the wastewater emission from 2013 to 2015 in China was predicted. Industry characteristics of wastewater emission between the whole nation and Haihe River basin were analyzed using the 1999 and 2002 water conservancy input-occupancy-output (IOO) tables. The results showed that the national wastewater emission of 2013-2015 will reach 72998, 76897 and 81071 million tons respectively, and industries like paper printing and educational goods manufacturing, chemical industry, discharged a large amount of wastewater and their wastewater emission by unit value added were also very high. In the meantime, wastewater by unit value added of metal smelting and rolling processing industry went down largely from 1999 to 2002, which revealed that the strict supervision had positive effects on reducing wastewater emission.
