Problems solved by technology

A large number of constructed wetland sewage treatment projects have been built in Europe, America and my country. However, in the actual operation process, it was found that the sewage flow state in constructed wetlands is very complicated, especially the most commonly used horizontal subsurface flow constructed wetlands. Under the traditional single-outlet water collection conditions, The horizontal flow state of the sewage cannot be fully guaranteed, and phenomena such as short flow, channel flow, and dead ends are more likely to appear in the bed, which affects the full play of the sewage purification function of the wetland system and causes the deterioration of the effluent water quality. At the same time, these abnormal water flow phenomena can easily lead to Local accumulation of organic matter, thereby accelerating the blockage of the constructed wetland bed, greatly shortening the operating life of the wetland, and seriously hindering the popularization and application of the constructed wetland treatment technology

Embodiment Construction

[0013] The invention is a water outlet collector for artificial wetlands, which includes five parts: a perforated water splash wall, a gravel buffer zone, a flute-shaped pipe water collection device, a water collection tank and a centralized water outlet device.

[0014] The perforated water splash wall is set according to the width of the wetland, and the holes are evenly punched from top to bottom, which can control the water outlet of the wetland, ensure the uniform distribution of the incoming flow, ensure that the water flow in the wetland flows in a parallel state, reduce short flow, channel flow and dead ends in the wetland, and ensure The wetland system operates stably and reliably.

[0015] The gravel buffer zone is evenly filled with gravel of a certain size, which plays a role in controlling the flow velocity of the water flow and reducing kinetic energy, and at the same time can further maintain the uniformity of the effluent water flow in the section.

Abstract

The artificial wetland effluent collector as one effluent collector for sewage treating artificial wetland includes two parts, a buffering gravel region and a water collecting groove. The buffering gravel region has a perforated water distributing wall for controlling water flow from the wetland and ensuring homogeneous distribution of the inflow, and a flute-shaped collecting pipe in the effluent side for collecting water. The flute-shaped collecting pipe comprises several flute-shaped pipes with valve and water collecting unit. The present invention can ensure the pseudo-parallel flow state of sewage in the wetland.

Description

technical field [0001] The invention relates to an artificial wetland water collection device used for sewage treatment, and belongs to the technical field of sewage treatment device manufacturing. Background technique [0002] Constructed wetland is a sewage ecological treatment technology that has been widely studied and applied since the 1970s. It has the advantages of high efficiency, low consumption, low investment and low maintenance technology, and its good promotion and application prospects have been gradually recognized. A large number of constructed wetland sewage treatment projects have been built in Europe, America and my country, but in the actual operation process, it was found that the flow state of sewage in constructed wetlands is very complicated, especially the most commonly used horizontal subsurface flow constructed wetlands, under the traditional single outlet water collection conditions, The horizontal flow state of the sewage cannot be fully guarantee...
