"Twelve Five" "Thirteen Five" urban sewage treatment facilities construction are as follows: national domestic county completed a total of 3802 sewage treatment plants, sewage treatment capacity of 161 million cubic meters / day. National domestic sewage treatment plant up and running 2149, the formation of sewage treatment capacity of 132 million cubic meters / day. All counties built sewage treatment plants 1653, the formation of sewage treatment capacity of 029 million cubic meters / day. 1427 county has built a sewage treatment plant, accounting for 88.4% of the total county. Treatment and disposal of sewage sludge to 2014 urban sewage treatment rate of 90%, the county sewage treatment rate reached 82%, and the village sewage treatment rate of sewage treatment plant upgrade 10% of the key areas in full swing harmless sludge treatment disposal rate of about 56% of the 2014 total length of 510,000 km drainage network 鍩庨晣姹℃按澶勭悊锛岃繖浜涙暟鎹€煎緱鎬濊€? width= the number of sewage treatment plants of 2014 Chinas urban sewage treatment plant in 3802 鍩庨晣姹℃按澶勭悊锛岃繖浜涙暟鎹€煎緱鎬濊€? align= "second five" major tasks sewage treatment 1, to further improve drainage network.

First, the water depth treatment is not enough. Excluded several large cities have this ability, there are a few cities such as North Canton water treatment technology does have depth, Beijing called after water treatment to meet the standard, there are a few that I askBeijing? Depth of the water treatment plant is currently less than 2%, which means that our drinking water is still not guaranteed technical. Less than half the proportion of qualified water source of water if the water into the plant but also to maintain good, then even if the water process needs to be improved, we can still say that water out of the water is acceptable, but sadly true of water into the water qualified are less than the general proportion. All over Columbia River, Haihe River inferior 鈪?water as high as 40% or more, the Yellow River, Huaihe, Liaohe and also have more than 20% is still inferior class 鈪?water. Since the water environment situation is still bad, we should continue to work hard in what way? Currently the focus is to improve the governance of the pipe network 鈶? 鈶?village sewage treatment, upgrading rural sewage 鈶? 鈶?sludge treatment and water reclamation
