The invention relates to a residence community domestic sewage treating system. The system comprises a black water collection system, an anaerobic acidification reaction tank, an anaerobic gasification reaction tank and an aerobic contact oxidation tank, the black water collection system is communicated with the lower portion of the anaerobic acidification reaction tank through a black water inlet pipe, an outlet of the anaerobic acidification reaction tank is communicated with an inlet of the anaerobic gasification reaction tank, an outlet of the anaerobic gasification reaction tank is communicated with an inlet of the aerobic contact oxidation tank, a brown water collection system is communicated at a position of the inlet of the aerobic contact oxidation tank, the outlet of the aerobic contact oxidation tank is communicated with an aerobic filter tower, a grey water collection system is arranged at a position of an inlet of the aerobic filter tower, a methane collection tank is communicated with the top of the anaerobic acidification reaction tank and the anaerobic gasification reaction tank, the methane collection tank is connected with a gas-fired boiler, the gas-fired boiler is connected into the anaerobic gasification reaction tank through a pipeline, and the inlet of the anaerobic gasification reaction tank is connected with an alkaline liquor adding system through the pipeline. The residence community domestic sewage treating system and a method have the advantages that the system is simple, the sewage treatment effect is good, the construction costs are low, and the land occupation is small.

The invention relates to a window mounted on a building wall and a manufacture method thereof, and belongs to the building field. A water collecting box (1), aquariums (31), flowerpots (15) and kaleidoscopes (20) are arranged in houses and noisy, messy and contaminated outer screen positions, flowers are planted, and fishes are bred. Besides, rainwater is collected, so that tap water is saved by more than 80%, and the rainwater forms a spectacular waterfall and drives the kaleidoscopes (20) to rotate to present changeable flowers. Accordingly, not only the decoration is livable and ecological and natural wonderful sceneries are created, but also green and environment-friendly positive effects of suitable lighting, radiation reduction, smoke prevention and dust control, air purifying to 98%, noise reduction and temperature and humidity adjusting are provided. Simultaneously, the window mounted on the building wall not only caters to people habits of standing in front of windows to breathe and overlook, but also meets people hobbies of fish breeding, flower planting and gardening design, and the window is a brand novel upgraded window which is necessary for home living and capable of keeping health of family members.

The invention discloses a vertical rainwater zoning drainage system which comprises a concave green area, a low-zone rainwater disposal facility and a high-zone rainwater disposal facility, wherein the low-zone rainwater disposal facility comprises a municipal rainwater inspection well, a road gully on the side of a road, and a sheetflood gully in the concave green area; the high-zone rainwater disposal facility comprises an overflow gully in the concave green area, a water collecting basin and an emergency rainwater discharge pump set; the overflow gully is connected with the water collecting basin; the water collecting basin is connected with the emergency rainwater discharge pump set; a delivery outlet of the emergency rainwater discharge pump set is communicated with an urban flood drainage channel or a ravine or a depression; the municipal rainwater inspection well is communicated with the sheetflood gully; the road gully is connected with an overflow communicating pipe; an outlet of the overflow communicating pipe is communicated with the concave green area; the overflow gully is designed in the specification that P is greater than set P; and the sheetflood gully is designed in the specification that P is less than or equal to set P. The system nips in the bud, can effectively prevent and treat a waterlogging disaster generated by rainstorm, can ensure personal and property safety, and changes passive salvation after the disaster into positive prevention and treatment before the disaster.
