Abstract

Reducing the quantity of excess sludge has become a popular research subject in wastewater treatment. Therefore, based on the current sludge reduction theory, some special microbial strains were selected, and through certain cultivation process, a multiifunctional compound microorganism product was developed to reduce the sludge quantity. The microorganism product was used in sewage wastewater treatment plant for pilot test. Five sets of identical equipment with the A2/O process and the same operating method were adopted, and the effect of SV and MLSS were analysed. The effects on sludge reduction were compared.The results show that the sludge reduction reaches 57.3%. The multifunctional compound microorganism product improved the effluent quality and the COD, NH3-N and TN in the effluent are 37.85mg/L, 0.30mg/L and 12.37mg/L respectively. The microorganism does not require any special treatment unit, and does not change the original treatment process also. Therefore, the microorganism product will effectively improve the sludge reduction effect, and reduce the pressure of the sludge disposal for the wastewater treatment plants.
