Application of Plate and Frame Press Filtration Dewatering Technology in Sludge Treatment of Waterworks
In order to reduce the operating cost of waterworks,the application of plate and frame filtration dewatering technology in sludge discharge water treatment was studied.Taking Changqiao Waterworks as the research object,the sludge water treatment of waterworks is completed by plate and frame press dehydration technology,and the dehydration is completed by diaphragm plate and frame filter press;The design parameters of diaphragm plate and frame filter press are analyzed,and the filter cloth of filter press is selected according to the properties of filter substances.Finally,the sludge dewatering work is completed through five parts:mud feeding,backblowing,dehydration,mud unloading and filter cloth cleaning.The experiment shows that this method has the advantages of higher solid content and better dewatering effect.
