Next-generation wastewater treatment must be environmentally sustainable by achieving recovery of resources (energy, nutrients, clean water), meeting discharge standards for nutrients and emerging contaminants, and minimizing waste sludge generation. This requires revolutionary ideas. An innovative treatment concept, i.e., NEO-GREEN concept, for meeting this demand is proposed.
“Our goal is the recycling and regeneration of wastewater, and we focus on the removal of COD, nitrogen and phosphorus from wastewater.”
—— Prof. Xinmin Zhan
What We Do
Livestock Wastewater
The components of livestock wastewater typically include organic matter (COD), nitrogenous compounds, phosphorous compounds and solid residues and suspended particulate matter from animal manure. Effective wastewater treatment of wastewater is essential to reduce the negative environmental impacts of livestock wastewater.
Anaerobic Digestion (AD)
Livestock wastewater will be sent to a wastewater treatment plant for AD process. AD process consists of a hydrolysis phase, an acid production phase and a gas production phase. During this process, many usable resources such as hydrogen sulfide, methane gas, acetic and butyric acid are generated.
Nitrification Process
The digested effluent contains large amounts of ammonia and phosphate. Ammonia can be oxidized to nitrite and nitrate by microorganisms with nitrification functions. Phosphorus cannot be removed in this process. But ammonia can be oxidized to nitrite and nitrate by nitrifying microorganisms , and they can be converted to gaseous nitrogen by denitrifying microorganisms to escape from the water body.
Simultaneous Nitrogen And Phosphorus Removal
Iron sulfides – based biotechnology includes denitrification and Feammox processes that can convert soluble nitrogen into gaseous nitrogen. At the same time, the dissolved iron ions can form a precipitate with phosphate to remove phosphorus from the water.
Achievements
As researchers in the field of wastewater treatment, NEO-GREEN concept requires us to pay attention to every step of the wastewater regeneration process. Many of the details cannot be stated in one or two sentences. If you want to learn more about what we have done, click here.
