The application relates to the roadway drainage field and discloses a novel roadway efficient drainage device, which comprises an outer through pipe, a water inlet pipe, a sewage storage bin, a drainage port and a variable-diameter port, an inner through pipe, an air inlet pipe and an air outlet pipe, and a sewage port one is arranged on the outer surface of the water inlet pipe; the inner through pipe is composed of the air inlet pipe and the air outlet pipe, and a sewage port two corresponding to the sewage port one is arranged on the outer surface of the air inlet pipe. The device utilizes the introduced high-pressure wind to generate negative pressure in the air inlet pipe inner cavity, and sewage is sucked through the sewage port one and the sewage port two, so that the sewage continuously flows to the left along the air outlet pipe and the sewage storage bin, the flow rate is increased when passing through the variable-diameter port, and finally the sewage is discharged along the drainage port. The device has the advantages that: the volume is small, the device is more flexible to deploy than a wind pump, the narrow space inside the device utilizes the Bernoulli principle to significantly improve the drainage efficiency, the sewage port one and the sewage port two are designed to enable the device to have a certain filtering function, and the overall practicability is enhanced.

This application discloses a grey water reuse treatment device, including a filtration mechanism, a reuse water tank, and a waste tank. The upper end of the filtration mechanism has a grey water zone A, which is connected to the drain outlet of a washbasin via an inlet pipe. The middle part of the filtration mechanism has a clean water zone B, which is connected to the reuse water tank via a filter suction pipe and a backwash suction pipe. The end of the filtration mechanism has a wastewater discharge zone C, which is connected to the waste tank via a wastewater discharge pipe. The grey water reuse treatment device provided by this application can effectively improve the service life of the filter by backwashing, eliminating the need for frequent filter element replacements and reducing maintenance costs. Simultaneously, the addition of a bactericide inhibits the growth of microorganisms.
