Zhejiang Jiaxing pioneering to build wetland purification of drinking water

in new network Jiaxing on 7 July, (Zhao Yejiao Li Jin) Jiaxing Cheap Customized Jerseys City, Zhejiang province at the end of the Taihu River Basin, upstream "guest water" pollution is serious, threatening the safety of drinking among the urban residents in Jiaxing. To this end, the city's first, upstream of the two water plant, each built a multi-stage purification of artificial wetland ecosystem. The wetland is not general, wetlands "multi-level interception and root hole cleaning combination" technology innovation is the core for water purification. Along the park like wetland walk to the water outlet of the tap water factory, many visitors will scoop up a spoonful of water, drained. Cheap NBA Jerseys

Jiaxing city has two water plant, respectively is the Shijiuyang waterworks and Guan Jing Gang waterworks, the overall water quality for class Ⅳ - Ⅴ water.

said without Cheap Club Soccer Jerseys exaggeration, Jiaxing city and the surrounding have been found not in conformity with the national standards for drinking water.

to solve the water problem, in 2009, Jiaxing city invested 67000000 yuan, in Shijiuyang waterworks water intake Cheap CFL Jerseys upstream protection zone, built a 1630 acre water wetland ecological engineering.

based on other Shijiuyang wetland good running effect, in 2011, Jiaxing City Guan Jing Hong water ecological wetland construction in the southern suburbs of the city, the project estimates a total investment of 228000000 yuan, and put into trial operation in 2013 October joint.

the whole wetland projects with a total area of 3737 acres, including pure wetland area of 1214.4 mu, land afforestation area of 2523.3 mu, design using the wetland root hole principle, including wetland buffer zone of self purification, root hole ecological purification area, botanical garden, water purification area 4 functional areas.

, is the core of the wetland root channels ecological purification area. In this region, most of core is the ecological environment research center, Chinese Academy of Sciences "multi-level interception and root hole purify the combination" technique. Utilization of wetland plants, soil root hole, changes in the wetland area level, degradation and absorption of pollutants in water.

"wetland was Cheap T-Shirts built, its purification process is relatively slow, complete purification process takes 10 to 15 years, the longest 30 years. So we should take some measures, including the implantation of straw man-made, let stalk rot play purification function. At the same time, wetlands planted with Phragmites australis, water hyacinth, algae and other plants, accelerated artificial root hole transition to the natural root holes, so only need 8 months will be able to form the purification ability." Professor Wang Weidong of Research Center for eco Chinese Academy of Sciences said.

Compared to

and other purification methods, where wetland purification advantage?

Jiaxing water group general manager Chen Yulin introduction, the biggest benefit of ecological wetland is pollution-free, no side effect. The natural precipitation, suspended solids immersed down, plant roots and soil to intercept function, in addition, protists, algae, higher plants, the organic matter in water is broken down into small molecules by enzymes.

"water hyacinth, Alternanthera philoxeroides, reed, soon > these plant absorption of nitrogen and phosphorus and potassium in water
