    Abstract:

    A filamentous fungi strain named Talaromyces flavus S1 was isolated from the municipal sludge. The dewaterability of sludge could be improved remarkably when the mycelium was inoculated to sludge. The results show that it is the mycelium itself rather than fungal secretions（Microbial flocculatants） improved the sludge dewaterability by separtating the culture solution of mycelium；The dewaterability of high concentration sludge was improved significantly by adding the fungal mycelium，as well as，it could be increased by 40.58%. When the sludge concentration is low，the dewaterability is even poorer than the raw sludge；The Capillary Suction Time（CST） of the sludge by conditioning of mycelium shows greater reduction compared with the Polyacrylamide（PAM） and polyaluminum ferric chloride（PAFC），but PAM is more effective to the specific resistance of sludge（SRF），while，the role of PAFC is weakest. The sludge dewaterability could be improved by 60% under the synergistic effect of PAM and mycelium. From the results of sludge particulate distribution and Scanning Electron Microscope（SEM），it shows that the dewaterability was advanced by the enlargement of sludge floc and particulate due to the small sludge particulate was wrapped by the mycelium. In a word，a more effective and reliable biological conditioning method is put forward to improve the sludge dewaterability on the basis of using the fungal spores. The results have an important significance to develop a new biological technology on sludge dewatering based on this filamentous fungi.
