Shell Powder for Strengthening Phosphate Removal Efficiency in Wastewater Treatment

Abstract:

Phosphorus removal from wastewater has always been given serious attention in sewage treatment. Eutrophication can happen if phosphorus wastewater is directly discharged into natural water and high phosphorus-contained irrigation water may lead crops beat down. The research investigated the phosphorus removal efficiency in wastewater by shell powder. The experiment results showed that the best removal effect could meet the Wastewater Treatment Plant Discharge Standard (GB18918-2002) Grade I-A in China, which can be achieved under the conditions of the dosage of shell powder solution 1 ml, pH > 11 and precipitation one to four hours at the initial phosphorus concentration of about 3 mg/L.
