Title: Sludge treating method
Inventor: YORINOBU FUMIO
IPC: C02F1/24
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To separate sludge from water by perfectly floating the sludge for a short time at the most important solid-liquid separation step in the continuous steps and to reduce the moisture content, which is 75% in the present state, of the cake-shaped sludge after dehydration. SOLUTION: At first, charcoal powder and chitosan in the natural field is added to liquid sludge by about half of the liquid sludge or smaller based on measurement weight without using chemicals for making the sludge apt to flocculate and float. Next, the power of bubbles, which are generated when the pressurized oxygen solution prepared beforehand is purged into the liquid of atmospheric pressure, is used as assistance for floating the sludge for a short time in a floating tank where the concentrated sludge is gathered by pumping it up. The floated sludge is dehydrated to obtain cake-shaped sludge that has 800% moisture content and about one-tenth volume of the concentrated sludge.  The cake-shaped sludge contains the charcoal powder of 100% or more amount of the total solid content and can be dried at accelerated drying speed by making good use of air permeability being the characteristic of the charcoal powder and generating cracks in the sludge having viscosity. The obtained sludge is used as not only a nonpolluting soil reducing material but also a good agricultural material by composting it into fertilizer.
