ABSTRACT
Widely application of CWs (Constructed Wetlands) in domestic wastewater
treatment of China is developing wetlands into a multi-function wetland system.
Wetland center in CAMIP (Changshu Advanced Materials Industrial Park) (Suzhou,
Jiangsu Province, China) successfully improved tail water quality to level IV
of Environment Quality Standards for Surface Water
(GB3838-2002) by the combination of different CW steps and achieved water reuse
in CAMIP for industrial purpose. Different from traditional tail water advanced
treatment, wetland center is designed under the principle of combining
landscape and ecological treatment technology. Since this center started
running, the removal rate of TN (Total Nitrogen), NH3-N, TP (Total
Phosphorus) and COD (Chemical Oxygen Demand) reaches 87%, 91%, 44% and 60% respectively.
Also, 2,038,000 m3 industrial water reuse in 2015 and 2016 was
achieved; emission reduction on COD, NH3-N and TN reached 100 t, 7.2
t and 15.2 t; an ecological garden that combines ecological wastewater
treatment, wetland landscape, habitat renovation and educational functions was
created.
