WASTE WATER TREATMENT METHOD AND WASTE WATER TREATMENT APPARATUS USING ULTRASOUND COMBINED SOLAR COLLECTOR

摘要

PURPOSE: A water treatment method and a water treatment apparatus are provided to conserve costs needed for maintenance and to improve the effect of pollutant removal from wastewater. CONSTITUTION: A water treatment method includes the following steps: a photo-catalyst is injected into wastewater; the wastewater is irradiated with ultrasound waves; and pollutants in the wastewater are decomposed by using a solar light concentrated reactor. The solar light concentrated reactor is a compound parabolic concentrator(CPC). The injection amount of the photo-catalyst is 0/2 to 1g/l. The frequency of the ultrasound waves is in a range between 20 and 1000 kHz.
