Modular vertical flow constructed wetland sewage plant tail water treatment device and method thereof

Abstract

The invention discloses a modular vertical flow constructed wetland sewage plant tail water treatment device which comprises a wetland pool body, a plant matrix module, matrix modules, an aeration device, a water inlet groove, a water inlet pipe, a water distribution pipe, a water storage pool and a water outlet backflow device, a pool body matrix filler is arranged in the wetland pool body, and the water inlet pipe is arranged at the lower end of one side of the wetland pool body; the water inlet pipe is connected with the water inlet groove, the bottom of the wetland pool body is connected with the water distribution pipe, the water distribution pipe is connected with the water inlet pipe, the water storage pool is arranged at the upper part of the other side of the wetland pool body, the water outlet backflow device is arranged at the bottom of the water storage pool, and a water outlet pipe is arranged on the water storage pool; the aeration device is arranged at the middle upper parts of the plurality of layers of matrix module groups; the invention further relates to a tail water treatment method utilizing the device, on one hand, the upward vertical flow constructed wetlandis adopted to properly relieve blockage, and the influence of blockage on a wetland system is reduced by the method; on the other hand, the wetland substrate is modularized so that when the wetland isblocked, a new module or matrix unit is convenient to use through replacement and the subsequent maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of tail water ecological treatment, and in particular relates to a modularized vertical flow artificial wetland sewage plant tail water treatment device and a method thereof. Background technique [0002] In the face of the current severe water resource shortage, traditional methods of increasing revenue and reducing expenditure can no longer solve the fundamental problem. Urban reclaimed water, long-distance cross-basin water transfer and desalinated seawater have become non-traditional water resources that have emerged in recent years. Compared with long-distance cross-basin water diversion and desalinated seawater, urban reclaimed water has many advantages, such as nearby availability, easy collection, huge quantity, stability and reliability, etc. It is mainly achieved by reusing treated sewage that meets the standards for industry and agriculture. . At present, there is still a gap between the first-le...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to further improve the water quality of the tail water of the sewage plant to meet the requirements of regeneration and utilization, and at the same time, taking into account that the vertical flow constructed wetland technology usually has fillers that are easy to clog and the resulting insufficient oxygen supply and low denitrification efficiency Advanced problems, overcome the shortcomings of the prior art, and provide a modular vertical flow constructed wetland sewage plant tail water treatment device and method. The impact of the system; on the other hand, the wetland matrix is ​​modularized. When the wetland is blocked, it is easy to replace with a new module or matrix unit, which is convenient for subsequent maintenance and easy to operate.
