What is one way natural ecosystems can perform wastewater treatment

Community Sources It has long been known that natural wetland areas such as marshes, swamps, and bogs, for example play an important role in protecting water quality. Constructed or artificial wetland systems mimic the treatment that occurs in natural wetlands by relying on plants and a combination of naturally occurring biological, chemical, and physical processes to remove pollutants from water. In fact, some constructed wetland system designs closely resemble natural wetlands and even provide additional habitat area for the many birds, animals, and insects that thrive in wetland environments. But because constructed wetland systems are designed specifically for wastewater treatment, they work more efficiently than natural wetlands.

Received Feb 8; Accepted Apr The higher the temperature was, the higher was the observed removal in this system.

Additionally, each unit of the system functioned differently in removing pollutants. BOD5 and SS were mainly removed in the first three units hybrid facultative ponds, aeration ponds and aerated fish pondswhereas nitrogen and phosphates were mainly removed in hydrophyte ponds and constructed reed wetlands.

The multi-stage ponds-wetlands ecosystem exhibits good potential of removing different pollutants, and the effluent quality meet several standards for wastewater reuse.

Unfortunately, algae would bloom in the ponds and cause secondary pollution of the following stream. To tackle this problem, several methods combining both ponds and filtering system had been tried Christian et al.

Dongying multi-stage ponds-wetlands ecosystem was designed embodying these ideas. Built on the basis of traditional stabilization pond and wetland technology, the Dongying multi-stage ponds-wetlands ecosystem possesses many advantages. Firstly, this system is composed of several eco-ponds and wetlands in certain proportion and fashion, basing on the ecosystem concept.

Secondly, this system has several functions: Therefore, it is especially suitable for developing countries such as China. Additionally, effects of temperature on different pollutants removal in different units were also studied.

This kind system can substantially improve the performance, and assure high removal efficiency for various pollutants while water is being reused and recycled. In addition to some pretreating units such as screening and grit chambering, the Dongying multi-stage ponds-wetlands system comprises two main parts Fig.The following are the natural performances of wastewater treatment: Simplicity: The designing of the plants is very simple and easy to maintain.

Water Purification is one of the many services provided by ecosystems. Pollutants such as metals, viruses, oils, excess nutrients, and sediment are processed and filtered out as water moves through wetland areas, forests, and riparian zones.

Ask students what natural ecosystems could perform the functions of these items. (Hint: ponds, wetlands, and forests). It might be a little more challenging to mimic the functions of the living organisms that contribute so much to water purification.
