NOVELTY - A comprehensive treating system comprises a sewage ecological balance processing system, and a solid-waste processing system. The main building of the processing system has a structure of overlapping the solid-waste processing building and the sewage processing building from top to down.    USE - A comprehensive treating system for urban river water region ecological environment.    ADVANTAGE - The system reduces building investment, is environment friendly, has improved yield, and has strong region adaptability.    DETAILED DESCRIPTION - A comprehensive treating system comprises a sewage ecological balance processing system, and a solid-waste processing system. The main building of the processing system has a structure of overlapping the solid-waste processing building and the sewage processing building from top to down. The pumping settlement in the undercurrent settlement pool and the siphoning liquid slug in the fermenting pool can be organically solved via the structure height difference. The undercurrent settlement pool is connected with the anaerobic fermenting pool by a vertical venting pipeline. The venting pipeline is used for that the green house gas produced by the undercurrent settlement pool enters in the anaerobic fermenting pool storage cavity that is transported to the methane purifying device via the methane venting tube to produce the gas energy source; and for discharging the liquid excessive in the anaerobic fermenting pool to the undercurrent settlement pool via the venting tube. The waste slug is dried in the waste slug drying pool transporting the liquid in slug pool to the bacteria liquid pool via filter pool and is pumped by bacteria liquid pump. The sealed undercurrent settlement pool is used for solving the air pollution process of naturally discharging the green house gas and for reducing the naturally discharging degrees of green house gas for filtering and sucking the sewage organic matter. The filter poll has closure aerobic groove that is used for shutting wet undercurrent filter band and oxidizing the organic matter in the water.
