Simultaneous removal of phosphorus and dissolved organic matter from a sludge in situ reduction process effluent by coagulants

Abstract

Owing to the long solids retention time and effective sludge decay, the increase in the amount of phosphorus and dissolved organic matter (DOM) in effluents is a major obstacle to the sludge in situ reduction process.

Structural characteristics, analytical techniques and interactions with organic contaminants of dissolved organic matter derived from crop straw: a critical review

“…With economic and social development, organic pollution in soils has become a common environmental issue. 1 The organic contaminants (OCs), originating from sewage irrigation, animal manure, pesticide application, atmospheric deposition and waste dumping, have entered into farmland soils, and participated in different natural geochemical and biological processes. [2][3][4] The source, composition and structure of dissolved organic matter (DOM) with the molecular weight distributed widely are very complex.…”
