摘要： A reactor for sewage treatment includes: an inner layer including a water distribution zone; a middle layer including a biological aerated filter, the biological aerated filter including a wall and a bottom including a water outlet; and an outer layer including an artificial wetland, the artificial wetland including a bottom including a water inlet. The water distribution zone, the biological aerated filter, and the artificial wetland are in the shape of a circle. The sewage is introduced into the water distribution zone via a water inlet pipe. The water distribution zone communicates with the biological aerated filter via a first overflow. The water outlet arranged on the bottom of the biological aerated filter is connected to the water inlet arranged on the bottom of the artificial wetland to allow the biological aerated filter to communicate with the artificial wetland.

摘要： A system for treating and recycling rainwater, including at least three stages constructed wetlands disposed along a sloped surface. Each stage constructed wetland includes a coarse gravel layer, a fine gravel layer, an improved soil layer, and wetland plants from bottom to top. Slopes are disposed at two sides of the upper part of each constructed wetland and are different in heights. An intermediate overflow pipe is disposed at the top of the slope between every two adjacent constructed wetlands. A last overflow pipe communicates with a municipal rainwater pipe. The coarse gravel layers of every two adjacent constructed wetlands are connected by connecting pipes. A perforated water collecting pipe is disposed at front ends of the connecting pipes. A water outlet pipe is disposed in the bottom of the coarse gravel layer of a last stage constructed wetland and is connected to a clean water reservoir.

摘要： A rainwater head, including: a dome, a drainage pipe, a siphon, and a ball cock mechanism. The drainage pipe includes a drainage exit and a wall including a water outlet hole. The ball cock mechanism includes a floating ball, a connecting bar, a fulcrum, and a stopper. The drainage pipe is connected to the lower part of the dome. The drainage exit is arranged on the top of the drainage pipe. The drainage exit is adapted to be between 5 and 10 cm higher than the roof. The water outlet hole is arranged on the wall of the drainage pipe at a position having the same height as the roof or is lower than the roof. The siphon is disposed on the upper part of the drainage pipe. The inlet of the siphon faces the roof; and the outlet of the siphon extends inside the drainage pipe.

摘要： A system for reducing emission of nitrous oxide during sewage treatment, including: a regulating pool, a first aerobic constructed wetland, an anoxic pool, and a second aerobic constructed wetland. The water outlet of the regulating pool is connected to the water inlet of the top of the first aerobic constructed wetland via a pipe and a first control valve. The first aerobic constructed wetland includes sequencing batch constructed wetlands arranged in parallel. A branch pipe and a second control valve are disposed on the pipe between the regulating pool and the first aerobic constructed wetland. The outlet of the branch pipe and the water outlet of the first aerobic constructed wetland are combined together and connected to the water inlet of the bottom part of the anoxic pool. The anoxic pool is an upward flow biological filter.
