PURPOSE:To decrease the amount of the consumption of water (well water or industrial water) and to strive for reducing the construction site by a method wherein the residue of excrements is sprayed in the high temperature area in the burning gas of a refuse incinerator, and the incineration of residue of excrements and the suppression of the generation of NOx are conducted at the same time. CONSTITUTION:Impurities, floating materials etc. removed by a residue removing equipment 9 are sent to a refuse pit 1 as residue 24 and are thrown into the refuse incinerator together with refuse 23 and are incinerated. And sand, iron pieces 23 etc., which are deposited in a sand deposition tank 6, are sent to an ash pit 5 after thoroughly washed at a deposited sand washing equipment 16. A part of residue of excrements 25, which are storaged in a storage tank 10, are sent to a spray nozzle provided in a spray zone 17 of the refuse incineration furnace 2 from a sewage spray pump 1, and are sprayed, and the incineration condition in the incineration furnace is improved and the generation of NOx is controlled. |
