【 摘 要 】
Economic growth arises fast in Taiwan because of the rapid development of industry, and many problems of environmental pollutions occur consequently. Wastewater and polluted water are the major pollutants occurred in the environment. As the result, plenty of researches related to wastewater reduction and treatment are developed to resolve the problem of wastewater production. The problem of wastewater production has been reduced after wastewater treatment tests have been used. However, the production of sludge increases accompanying with the volume of wastewater treatment, which causes numerous costs generated for dealing with sludge treatment. In general, successful technics involved in industrial sludge reduction are divided into five methods, including physical, chemical, biological, sludge hydrolysis, and a combination of the above methods. This study developed a method for sludge reduction by using ultrasonic technic with low consumed energy, combined with biotreatment (active sludge process) to conduct tests of organic sludge reduction in one industrial area of Taiwan. There is no use of chemicals on tests of organic sludge reduction, which resulted in no second pollutants generated by the application of ultrasonic technic, and organic sludges can be reduced. The results of the pilot and laboratory tests showed above 40% of sludge reduction, and this method was available to apply on the real filed operation.
