Assess the wastewater treatment efficiency of the rice paper craft village with activated sludge supplemented with probiotics

Abstract

This study was carried out to assess the wastewater treatment efficiency of rice paper craft villages with activated sludge supplemented with probiotics. With probiotic BHT preparation (including strains: Bacillus thuringiensis, Bacillus cereus, Bacillus sp., Pseudomonas sp., Saccharomyces cerevisiae), the density of
microorganisms of 108 CFU/g, selecting the appropriate retention time of 9 days for the highest treatment efficiency, in which COD treatment reached 81%, BOD5 treatment reached 82%, TSS treatment reached 55.7% and met QCVN 40:2011/BTNMT (column B)...
