<p>PROBLEM TO BE SOLVED: To provide a technology for removing pollutants effectively from a polluted environment. SOLUTION: An enzyme treatment tank 20 has a treatment space which receives wastewater overflowing from an ozone treatment tank 10 and stores it temporarily, In the space, an diffuser 21 which agitates the wastewater in the tank 20 and various sensors for monitoring the quality of the wastewater are provided to function as a enzyme treatment mechanism. For example, when lignin peroxidase is used as an enzyme, on the basis of the information of enzyme sensors 22a included in the sensors 22, the amount of the enzyme to be supplied from a cleaning agent supply part 23a as a conditioning liquid supply part 23 is controlled, and an enzyme concentration in the tank 20 is kept uniformly at 0.5-500 mg/liter.</p> |
