Effect of Ca2+ on cultivation of biomembrane aggregates of water treatment
|
Abstract:
An effective way to cultivate efficient biomembrane aggregates was researched by regulating the Ca2+ concentration of the influent in the five SBBR reactors(A,B,C,D,E).When the Ca2+ concentration of the influent was 25 mg/L,the biomembrane aggregates which were cultivated in the SBBR reactor D had the better anti-extrusion capacity.The average compressive strength of the biomembrane aggregates reached 22 N/cm2,the density was 1.059 g/cm3,and the percentage content of the active microorganisms was 86.90%.The...
