Abstract
The effect of temperature on the wastewater treatment with waste materials (refuse concrete and refuse waste) and natural material (shell) was investigated. The removal of suspended solid (SS), phosphate ion, nitrate ion, ammonium ion and chemical oxygen demand (COD) were evaluated for the temperature effect. Although the extensive improvement of removal efficiencies for nitrate ion and ammonium ion could not be achieved by increasing the temperature, the significant enhancement of the removal of SS and COD was observed. The present wastewater treatment system is simple, convenient and low-cost. Therefore, the developed methods can be applied to the small-scale plant for the wastewater treatment in the local and nonexclusive areas.[PUBLICATION ABSTRACT]
