Abstract
Much interest has been caused in the garbage recycling system like garbage disposer recently in Japan. To make clear the composition (quality), the discharge, and the loading characteristics of disposer wastewater from typical Japanese household is therefore of much importance, which is also regarded as one of the objectives of this research. Results of our investigation showed that the typical discharge of disposer wastewater was 5l·cap-1·d-1, the typical weight was 250g·cap-1·d-1, with its composition as vegetables 37%, fruits 30%, meat and seafood 16%, boiled rice 7.3%, used tea leaves 4.4%, and the others 5.3%. A typical garbage was selected and the loading characteristics were investigated. It was clear that the quality of the disposer wastewater was, T-BOD 5,500mg·l-1, T-COD 5,100mg·l-1, TOC 3,400mg·l-1, T-N 270mg·l-1, T-P 50mg·l-1, n-Hex 700mg·l-1, SS 7,100mg·l-1, VSS 6,500mg·l-1. Among them the undissolved part occupied about 75%. And the Solid Separate apparatus could reduce about 30% of the disposer wastewater pollution. In addition, it was also suggested that fresh residue exerted a larger influence on the loading disposer wastewater than vegetable. Moreover, disposer wastewater could increase the C/N ratio of domestic wastewater.
