Constructed wetland systems are a low-cost, low-energy-consumption and effective technology for water pollution control used increasingly in recent years in China. In this paper, the land treatment systems in China are introduced, the constructed wetland systems in North China are detailed, and the integrated reed bed wetland-lagoon system, as an advanced constructed wetland system, is compared with other land treatment systems. Lastly, the authors elaborate their opinion on problem “wetlands occupy larger lands” and energetically advocate to develop this new land treatment technique in China.

An estimated 80 % of all illnesses in developing countries is in one way or another related to water. In order to alleviate this most serious condition, the united Nations has initiated the “International Water Decade”, for which the estimated costs are $600 000 million, a sum which is far beyond any available means. By application of “low-cost technology” this sum could be reduced to $100 000 million which brings the objective within the reach of possibility. Details are given of the design and methods of construction of units which are best suited to the specific requirements and which would be simple, reliable and economical to operate. These can be constructed largely from local materials and by local labour. The need for appropriate training of both operators and the user population is stressed.

Unit Value

Constructed wetlands (CWs) are nature-based solutions (NBS) for water pollution control that can also be designed to be multipurpose in terms of additional ecosystem services (ESs), such as biodiversity support and social benefits. Awareness about additional ESs of CWs can be raised with value transfer (VT) methods for ESs monetization, in particular, the simplified adjusted unit VT method. A multi-criteria analysis (MCA) was performed to compare grey and green infrastructure alternatives for the management of a combined sewer overflow in the Buccinasco town (Italy), in which the criteria related to ESs were monetized with an adjusted VT method (B£ST software). The results highlighted the potential interest in the implementation of the green infrastructure in a new urban park, due to the activation of additional ESs of interest, such as health and recreational aspects. The results were also confirmed by a sensitivity analysis, which simulated the variation of preferences among different stakeholder groups (e.g., citizens, environmentalists). In conclusion, this work provided a transparent methodology to support decisions regarding green and grey infrastructure, allowing to evaluate additional ESs from the beginning of the decision stage with low cost and efforts.

Abstract In recent years, the rapid development of coastal areas has polluted the watershed water, affecting the ecological environment of wetland scenic spots. This paper briefly introduced the constructed wetland, a means of watershed water pollution control, and briefly explained its mechanism of water pollution control. Then, an example of Yancheng Coastal Wetland Natural Reserve in Jiangsu Province was analyzed to analyze water quality ecological changes in the basin before and after the construction of constructed wetland. The results showed that the basin of the natural reserve changed from acidic to alkaline, and ammonia nitrogen, total nitrogen, total phosphorus and chemical oxygen demand decreased significantly and maintained at a relatively low level after the constructed wetland controlled the water pollution in the basin; subsurface constructed wetland had a better effect on reducing ammonia nitrogen, total nitrogen and total phosphorus; surface constructed wetland had a better effect on reducing chemical oxygen demand. In conclusion, constructed wetlands as a means of water pollution control in the watershed can effectively improve the water quality ecology of coastal wetland natural reserves.
