Environmental impact assessment of dynamic simulation of water saving and emission reduction in Hebei Province

摘要

In recent years, the shortage of water resources and water pollutant emission in Hebei province have been accelerated with the process of urbanization. In order to solve the problems, this paper constructs a comprehensive dynamic simulation model of socio-economic, water pollutant discharge and water resources cycle based on material, water resources, value balance and input-output table. The study shows that under the best scenario (the introduction of new irrigation technology and new sewage treatment technology and new domestic faucet policy), In order to reach the 13th Five-Year Plan of water pollutant removal rate and water-saving targets, Hebei province needs to subsidize for new sewage treatment plant 8.7 billion RMB, build 47 new sewage treatment plants and subsidize for household faucets 1.01 billion RMB, besides, Hebei Province needs to subsidize for new irrigation technology 11.03 billion RMB.
