Can constructed wetlands be more land efficient than centralized wastewater treatment systems? A case study based on direct and indirect land use

چکیده
Compared with centralized wastewater treatment systems, constructed wetlands are generally regarded as not suitable for wide deployment due to the comparatively larger direct land area. Much of traditional thinking is based on an onsite perspective, while offsite information left out. By a comparative case study systems accounting both and use, this questioned picture found that can be more use efficient than systems. On unit treated basis, induced by typical wetland in China revealed less half plant or hybrid system. removal basis biological oxygen demand (BOD5), chemical (COD), total suspended solid (TSS) ammonia‑nitrogen (NH3-N), only around 61%, 67%, 73% 64% system, respectively. Meanwhile, indirect effect demonstrated significant these three systems: magnitude amounts times occupation wetland, one order higher scenario analysis 2017, it preliminarily estimated over two billion square meters could reduced if all replaced wetlands. The outcome may serve benchmark offers new way management

Constructed Wetlands for Wastewater Treatment: A Review
The first experiments on the use of wetland plants to treat wastewaters were carried out in the early 1950s by Dr. Käthe Seidel in Germany. The first full scale systems were put in operation during the late 1960s and since then constructed wetland systems have been spreading throughout the world. At present, there are several types of constructed wetlands used for wastewater treatment. Free wat...
متن کاملApplications of Constructed Wetlands for Wastewater Treatment
During the past decades, the high cost of conventional treatment processes has produced much economic pressure and they are not as natural methods as we expected. Thus, engineers begin to search for some creative, cost effective, and environmentally sound ways to treat wastewaters. Constructed wetland is a man made system which provides us many benefits and it is a very attractive way for many ...
متن کاملMunicipal wastewater treatment using constructed wetlands
The aim of the paper is to present alternative to conventional (i.e., the commonly used biological treatment plants) wastewater treatment systems, appropriate for small communities and settlements. These systems are the natural treatment systems. The emphasis here is given on constructed wetlands (CWs). First, advantages and disadvantages of these systems are presented compared to conventional ...
