Abstract

The predatory bacteria with high cell lysis capacity was isolated and screened from the activated sludge of a municipal wastewater treatment plant. The efficiency of sludge biolysis with an addition of the enriched predatory bacteria for enhancing its dewaterability was evaluated and the associated environmental impact factors were investigated. The results indicated that the predatory bacteria with a broad range of hosts were abundant in the municipal sewage sludge and greatly benefited sludge lysis. The concentration of the predatory bacteria enrichment could be improved with the increase of host dosage but not the concentration of the culture medium. When the neutral municipal sludge was incubated with the screened predatory microbes at the concentration of 106 pfu/mL for 24h at room temperature, the values of the specific resistance to filtration (SRF) and the volume of the treated sludge were 36% and 15% lower than the control sludge without bacteria addition, respectively. Meanwhile, the cell lysis led to the release of intracellular nutrients. The concentrations of total nitrogen (TN) and total phosphorous (TP) in the liquid phase of the treated sludge were increased by 245% and 242%, respectively and the ratio of SCOD/TCOD was increased by 195%. However, there is no positive correlation between the biolysis effect and the reaction time and the optimal sludge biolysis reaction time was 24h.
