Abstract

PURPOSE: To achieve the purification of waste water and the effective utilization of coal ash by forming the waste water purifying part by the soil layer mixed with the coal ash having the grain size distributions from fine grains up to coarse grains and organic materials such as sewage sludge.
CONSTITUTION: Fine grain coal ash 8 and coarse grain coal ash 9 of uneven form are mixed with organic sludge 10 such as sewage sludge to form a waste water purifying soil layer 4. When the waste water to be treated is sprinkled onto this soil layer 4 from waste water sprinkling pipes 6 as shown by arrows 7 and is let to pass therethrough, the waste water is purified and the purified water of extremely low COD and N, P amounts is discharged from a culvert discharge pipe 5 onto sea water surface 1. The soil layer 4 permits cultivation of crops and plantation of trees and in this layer the product of decomposition produced through the purification of the waste water acts as a nutrition source to help grow crops and trees well.
