NOVELTY - Sewage treatment system employing solar power supply comprises a solar power supply device, a blower and a sewage treatment device, which are connected serially. The sewage treatment device comprises an anoxic zone and an aerobic zone, which are successively connected. A bevel board settlement zone connected with the aerobic zone is arranged at the tail end of aerobic zone. The bevel board, a distribution energy dissipation tube and a sludge zone are arranged in the bevel board settlement zone.    USE - Used as a sewage treatment system employing solar power supply.    ADVANTAGE - The system can save energy by using the solar power; is environmental friendly; and can provide clean water after the treatment, which meets the water treatment standards.    DETAILED DESCRIPTION - Sewage treatment system employing solar power supply comprises a solar power supply device, a blower and a sewage treatment device, which are connected serially. The sewage treatment device comprises an anoxic zone and an aerobic zone, which are successively connected. A bevel board settlement zone connected with the aerobic zone is arranged at the tail end of aerobic zone. The bevel board, a distribution energy dissipation tube and a sludge zone are arranged in the bevel board settlement zone. The sludge zone is arranged at the bottom of the bevel board settlement zone. The distribution energy dissipation tube penetrates through the bevel board. An INDEPENDENT CLAIM is also included for treating sewage by using sewage treatment system employing solar power supply, comprising (i) performing denitrification treatment after retaining the raw water in the anoxic zone, (ii) retaining the raw water in the anoxic water for 4-9 hours to remove organic matters and ammonia-nitrogen to form nitration solution, and (iii) retaining the discharged water of aerobic zone in the bevel board settlement zone for 2-3 hours to settle and separate under the action of gravity.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the sewage treatment system employing solar power supply (Drawing includes non-English language text).
