At the same time, the wastewater discharge standard compliance rate rose
consistently, and as of 2010, the wastewater compliance rate surpassed 95 %. It
showed that conditions have further improved, but the total emission of wastewater
needs to be further controlled.
6.4.2 Reduction Goals of Chemical Oxygen Demand
During the 11th Five-Year Plan period, China set a target to reduce chemical oxygen
demand by 10 % and prioritized cleaning up drinking water sources. Furthermore, it
sped up the governance of pollution in key areas and comprehensively promoted
water resources protection as well as the prevention and control of water pollution.
The control of chemical oxygen demand has surpassed the intended target, and
ammonia nitrogen emissions have also been curtailed. (see Table
6.3
) In 2009, the
potassium permanganate index average concentration of the surface water control
section reached 5.1 mg/l., and dropped by 29 % compared with that of 2005, and the
rate of seven water system control sections with better than Level III water quality
increased from 41 % in 2005 to 57 %.
