NOVELTY - A sewage source pollution processing system has a sewage source drainage branch pipe for leading sewage into a distributing well. A dividing wall is provided with a sewage dry channel lead-in pipe interface and a main sewage discharge pipe interface. A first stage distributing well of the sewage discharge pipe interface is coupled with a next distributing well of the sewage dry channel lead-in pipe interface. A digestion tank is set on the water drainage main pipe for containing sewage drainage main pipe and the sewage slurry for carrying out anaerobic fermentation to generate marsh gas.    USE - Sewage source pollution processing system.    ADVANTAGE - The system has low processing cost and high processing efficiency, and can reach environment protection requirement of zero emission, and avoids abnormal smell, and is environment-friendly.    DETAILED DESCRIPTION - A sewage source pollution processing system has a sewage drainage main pipe, a sewage source drainage branch pipe for leading sewage into a distributing well. The distributing well is formed by a dividing wall. The dividing wall is provided with a sewage dry channel lead-in pipe interface and a main sewage discharge pipe interface. The distributing well is set at an upper part of an active sewage guiding opening and an overflow opening. The source sewage drainage branch is introduced with the distributing well through source sewage. The distributing well comprises two stages. A first stage distributing well of the sewage main discharge pipe interface is connected with a next distributing well of the sewage dry channel lead-in pipe interface that is connected with a waste water drainage main pipe of a water treatment wetland. An overflow port is connected with the water distributing well treatment wetland connected with a water overflowing port. A digestion tank is set on the water drainage main pipe for containing sewage drainage main pipe and the sewage slurry for carrying out anaerobic fermentation to generate marsh gas. An INDEPENDENT CLAIM is also included for a sewage source pollution processing method.
