| 摘要 |
The present invention provides a food waste disposal system including a BOD reduction apparatus comprising a concentrated-oxidizing tank, an aeration tank, an air pump and a filter. A drain of food waste disposal system is connected to a inlet of the BOD reduction system. Also, purified water in the BOD reduction system is carried back to a inlet of said food waste disposal system so that purified water is reused in food waste disposal system. A pH sensor, which can measure acidity and basicity, is mounted on a filter drain of the BOD reduction system. When pH of the sensor is less than pH 3, small quantity of caustic soda powder is input from a caustic soda tank mounted on the pipe of the rear end of a water supplying valve of the food waste disposal system to regulate the pH level of food wastewater.
