The invention discloses a compound organic waste water treatment system, comprising a water inlet system, a constructed wetland, an anaerobic reaction device, a gas separation device and a water outlet system. Primary treatment; the anaerobic reaction device is connected to the constructed wetland for secondary treatment of the water after the wetland treatment; the gas separation device can separate the carbon dioxide gas in the waste gas produced by the anaerobic reaction, and introduce the carbon dioxide gas into the constructed wetland ; The effluent system is connected with the anaerobic reaction device to discharge the wastewater produced by the anaerobic reaction. By organically combining the constructed wetland with the anaerobic reaction device used for sewage treatment, the invention can improve the utilization rate of sewage and realize the reuse of sewage while treating sewage in an advanced level, and can target sewage with high organic concentration and few large particles. , generally used for secondary and tertiary wastewater treatment, with strong practicability. |
