A bioretention pond includes a pond body and an overflow weir. The pond body includes a pond wall and a layered substrate. The layered substrate includes from bottom to top: a gravel layer, a transition layer, a pyrite layer, a plant layer, a pebble water layer, an organic layer, and a water storage layer. The overflow weir is disposed on the pebble water layer with a space left above the center of the pebble layer. The organic layer is disposed in the space and covers the pebble layer. The water storage layer is disposed onto the organic layer. The pond body further includes a perforated pipe disposed in the gravel layer; and the perforated pipe includes an outlet end disposed at the top part of the pyrite layer.

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.

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.

Reactor for sewage treatment

An integrated system for treating and recycling rainwater in a residential community. The residential community includes low-lying land. The integrated system includes a primary channel for receiving and treating initial rainwater, a baffled water treatment pool, and a reservoir. The primary channel includes an external wall and an inner wall. The baffled water treatment pool includes a water inlet which is disposed on the inner wall of the primary channel. The reservoir includes a water inlet, a gravel filter layer, and an overflow wall. The primary channel, the baffled water treatment pool, and the reservoir are disposed in the low-lying land. The primary channel is annular and surrounds the baffled water treatment pool and the reservoir. The overflow wall of the reservoir cuts off the annular primary channel. The baffled water treatment pool and the reservoir are adjacent to each other and are divided by a shared wall.
