AI Technical Summary

Technical Problem

The existing artificial wetland filler modules can easily cause sewage to overflow the bed surface when the sewage discharge is large, resulting in environmental pollution.

Method used

An improved artificial wetland filler module was designed, using a combination of liquid level sensor, PLC controller, micro motor, circular gear and baffle. The sewage flow is detected through the liquid level sensor. When the flow is too large, the micro motor control baffle is activated. Block the water inlet holes to prevent sewage from flooding; at the same time, set up an oxygen delivery pump to accelerate the oxidation and degradation of sewage and improve purification capacity.

Benefits of technology

It effectively avoids the overflow problem caused by excessive sewage flow, maintains the stable water body of the wetland pool, and improves the sewage purification efficiency and aquatic plants' survival and adaptability.

Abstract

The utility model discloses an improved constructed wetland filler module, which relates to the technical field of constructed wetlands and comprises a wetland pool body, a PLC (programmable logic controller) and a fixing block are fixed on one side of the outside of the wetland pool body, a water inlet hole is formed in the wetland pool body, a micro motor is fixed at the top of the wetland pool body, and a water outlet hole is formed in the bottom of the wetland pool body. A circular gear is fixed to the output end of the micro motor, a supporting rod is fixed to the top of the fixing block and sleeved with a long-strip-shaped gear, a connecting rod is fixed to one side of the long-strip-shaped gear, and a baffle is fixed to the end, away from the long-strip-shaped gear, of the connecting rod and inserted into a water inlet hole of the wetland pool body. When sewage overflows the surface of the wetland pool body, the liquid level sensor transmits an electric signal to the PLC, the PLC starts the micro motor, and the baffle is controlled to block the water inlet hole under the meshing movement of the circular gear and the long-strip gear, so that the sewage is prevented from overflowing the surface of the wetland pool body to cause environmental pollution.
