Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing;
[0024] Such as figure 1 As shown, the application of membrane treatment and oxygen-enriching device for black and odorous river treatment system, the sewage is sequentially processed through sewage pretreatment, facultative pond sedimentation, integrated membrane processor treatment, and after the sewage enters the flowing river, it is treated by high-concentration aeration device. Reaction treatment of black and odorous substances: Among them,
[0025] S1: Sewage pretreatment: One or more grooves 1 are set at the end of the sewage entering the river, and sand and gravel layers 2 are laid layer by layer on the bottom surface of the water outlet of the groove 1; The pollutants are partially precipitated; the surface of the sand layer 2 will form a natural biofilm system to remove the organic matter in the sewage;
[0026] S2: Settlement in the aerobic pond: Excavate the ae...
