بررسی کارایی تالاب‌های مصنوعی زیرسطحی هیبریدی در کاهش بار آلی پساب تصفیه‌خانه‌های فاضلاب شهری با استفاده از گیاهان آبزی مختلف
In this paper, the efficiency of four hybrid horizontal-vertical subsurface constructed wetlands which have been built for the tertiary treatment of Isfahan North Wastewater Treatment Facility and removal of organic matters was evaluated. In these constructed wetlands three plants including Phragmites australis, Typha latifolia and Arundo donax were planted and one unit left unplanted. The resu...
متن کاملPollutant removal by Canna Generalis in tropical constructed wetlands for domestic wastewater treatment
Constructed wetlands have not been commonly used in Vietnam due to the lack of information in the selection of proper types of constructed wetlands, type of reeds, design parameters and performance efficiency, in tropical climates. This paper focuses on Canna generalis, which is a common reed and easy to grow both in water and wet land conditions. Two kinds of hybrid constructed wetlan...
متن کاملAnammox enrichment and constructed wetland inoculation for improvement of wastewater treatment performance
This study contributes to the improvement of low-cost biotechnology for wastewater treatment in constructed wetlands (CWs). Constructed wetlands are energy efficient engineered systems that mimic the treatment processes of natural wetlands, removing polluting organic matter, nutrients, and pathogens from water. The aim of this study was to investigate the advisability of the inoculation of hori...
متن کاملInvestigating the efficiency of surface flow constructed wetlands by using Cyperus alternifolius plants for nitrate removal from water
Background and Objective: Synthetic wetlands are engineering systems that use natural plants, soils and organisms to purify municipal polluted water and remove nitrate. Materials and Methods: In this study, three systems were considerd as soil culture, three systems as plant cultivation on floating plates and three other systems without plant and porous bed as. The experiments were done three ...
متن کاملRemoval of Pharmaceutical Products in a Constructed Wetland
Background: There is growing interest in the natural and constructed wetlands for wastewater treatment. While nutrient removal in wetlands has been extensively investigated, information regarding the degradation of the pharmaceuticals and personal care products (PPCPs) has only recently been emerging. PPCPs are widely distributed in urban wastewaters and can be removed to some extent by the con...
