PURPOSE:To effectively treat the agricultural chemicals and nitrogen components in water and to prevent environmental pollution by effectively utilizing the organic chemical decomposing and denitrifying capacity of the BSK bacteria in treating the water in a regulating pond provided in a golf course, etc. CONSTITUTION:Spraying equipment 3 having a waste water treating chamber 5 through which the water in a pond is passed by spraying is set in the pond, and the water is treated by spraying and returned to the pond. A first treating part 19a packed with an anaerobic immobilizing carrier 21a is provided in the chamber 5 on the upstream side and a second treating part 19b packed with an aerobic and anaerobic immobilizing carrier 21b on the downstream side. The BSK bacteria are supplied into the chamber 5, aeration is carried out, and the bacteria are immobilized on the carriers 21a and 21b. The water is passed through the chamber 5 by spraying, the agricultural chemicals are deposited mainly in the first treating part 19a, and the water is then deaerated mainly in the second treating part 19b. |
