Treatment Of Sewage Sludge From Heavy Metals, Organics Pollutant And Metal Recovery From Fungi

Abstract

Sewage sludge is the semi-solid substance that is released as an end product during the treat-ment of wastewater. More focus needs to be paid to the treatment and reuse or disposal of sewage sludge because of strictly controlled law. Sewage sludge can be used as a fertilizer in agriculture, but the use of sludge is prohibited since it contains heavy metals, poisonous chemicals, bacteria, etc. The use of fungi treatment can assist in the recovery of waste sludge and it’s a substitute approach in the treatment of sludge. The aim of using this fungal treat-ment is to reduce a broad range of xenobiotics even at low concentrations due to the unspe-cific enzymatic system, especially in lignolytic fungi. This thesis focuses on sewage sludge-related topics such as substances, rules, treatment, and recycle. The main objective of the present work was to examine, in accordance with the law, the role of biological processes in the removal of heavy metals during fungal treatment.
