Abstract
The invention discloses a clogging-prevention vertical-flow wetland and a waste water treatment method. A waste water collecting pipeline collects waste water for entering a waste water adjustment and impurity removal device. The bottom of a wetland bed body is provided with a pulse water distribution device, and the upper part is provided with a pulse water intake device. Waste water enters the pulse water intake device after impurity removal through the waste water adjustment and impurity removal device. The pulse water intake device is connected with the pulse water distribution device. The wetland bed body comprises wetland stuffing and wetland plants. After pump-carried waste water is accumulated to be full in the pulse water intake device, the pump-carried waste water enters the bottom of the wetland in a pulse mode at a large flow-rate impulse. The process is repeated again and again. The defects of high short flow coefficient, easy clogging, and the like of a traditional wetland can be effectively overcome. After a long time, a hopper-shaped valve in an impurity-carried water pool of a starting original pump in a pool can remove rest sludge on the bottom of an upper flow wetland in a pulse mode so as to thoroughly prevent clogging.
