The present waste treatment (especially manicipal rebuse treatment) cannot rely only on national purifying, as the result, needs treatment cotrol being considered the enviromental pollution control.Incineration in Japan has been used for the above treatment, and it has been considered as the best procedure from the sight of decrease of volume, and stability of nature.The treatment and disposal procedure of waste in Japan consists 75% of incineration, 45% of land fill, 2. 5% of composting and 7. 6 of domestic treatment.The report has dealt with the procedure and condition of the incineration plant.The property of ash depends upon the incicinerator condition.The ignition loss shows about 10-15% (the standard ignition loss is less 15%), and it shows 8-20% at the continuous firing. The dust concentration by thc air pollution control restrains less 0.2g/Nm3 when the effluent gas volume is than 40, 000 Nm3/ hr., and 0.7g/Nm3 when less 40, 000 Nm3/hr.Generally, at the fixed grate incinerator the above concetration keeps less o. 7g/ Nm3 with the M. C., and at the most continuous incinerators, it keeps less 0.1.-0.2 g/Nm3 with E. P.The report added the description of toxious gasses and heavy metals.
