Evaluation of Organic Matter Removal Efficiency and Microbial Enzyme Activity in Vertical-Flow Constructed Wetland Systems
In this study, enzyme activities and their relationships to organics purification were investigated in three different vertical flow constructed wetlands, namely system A (planting Pennisetum sinese Roxb), system B (planting Pennisetum purpureum Schum.), and system C (no plant). These three wetland systems were fed with simulation domestic sewage at an influent flow rate of 20 cm/day. The resul...
متن کاملNutrients and Organic Matter Removal in a Vertical-Flow Constructed Wetland
Constructed wetlands are promising engineering technique that reproduce the conditions of the natural wetlands [1]. They have high water treatment capacity because of the intensive “work” of the plants and the microorganisms. Depending on the conditions various types of plants are growing: common reed (Phragmites australis), rush (Typha latifolia), iris, etc. (Fig. 1). These plants are stable t...
متن کاملSeasonal Variation of Nutrient Removal in a Full-Scale Artificial Aerated Hybrid Constructed Wetland
To improve nutrient removal, a full-scale hybrid constructed wetland (CW) consisting of pre-treatment units, vertical-baffled flow wetlands (VBFWs), and horizontal subsurface flow wetlands (HSFWs) was installed in August 2014 to treat sewage wastewater. Artificial aeration (AA) was applied continuously in the VBFW stage to improve the aerobic condition in the hybrid CW. Water samples were colle...
متن کاملNutrient removal efficiency by floating macrophytes; Lemna minor and Azolla pinnata in a constructed wetland
The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. This study assessed nutrient removal efficiency of two floating macrophytes (Lemna minor...
متن کاملNitrogen removal from industrial wastewater by hybrid constructed wetland systems
The efficiency in nitrogen removal from wastewater generated at CSBP Ltd fertiliser and chemical manufacturer by two hybrid constructed wetland mesocosms was compared. The mesocosms were set up in order to help clarify the reasons why the two year old constructed wetland located at the industrial facility, a 1.2 ha free water surface/vertical flow conjugated system, has performed under the 50% ...
