Ideas for Building the Concept Wastewater Treatment Plants in China
Activated sludge process (ASP) plays a leading role in pollutants removal from wastewater since its invention over a century ago. However, existing sewage treatment practices employing ASP can no longer satisfy the challenging demand arising from the promotion of Low Carbon, Green Growth strategy envisioned by the Economic and Social Commission for Asia and the Pacific (UN ESCAP). Under the guideline of this strategy, sewage should be considered as a renewable resource capable of converting organic carbon into clean energy, while simultaneously recovering both nitrogenous and phosphorus nutrients. It is imperative for us to brainstorm the blueprints of conceptual WWTPs incorporating such renewable technology. The construction of demonstrative sewage treatment plants (STPs) is already underway and will be operational between fiscal years 2030 to 2040. These demonstrative STPs will validate novel functionalities and treatment capacity that are necessary to satisfy the rising demand of China wastewater industry in the future. The outline of conceptual WWTP blueprints aims to: 1) implement water sustainability, 2) improve energy self-sufficiency, 3) incorporate effective material cycle, and 4) increase eco-friendly performance.
