Embodiment Construction

[0020] Such as figure 1 , 4 , 5, 6. The embodiment shown is a mud-water separation constructed wetland with vertical underflow. One end of the constructed wetland has a water inlet pipe 1 entering the water distribution well 3, and the other side of the water distribution well is connected to at least one water distribution pipe 5. The water distribution pipe 5 is located on the upper part of the filling matrix 7 in the constructed wetland, and a mud-water separator is provided in the water-passing process in the constructed wetland. Below the bottom plate of the mud-water separator, there is a clearing exhaust channel 11 and an exhaust pipe 13. The bottom of the constructed wetland is provided with a water collection pipe 6, and the treated water enters the water outlet well 4 through the water collection pipe 6, and is discharged from the water outlet pipe 4. The discharge pipe 2 discharges.

Abstract

The invention provides a mud-water separating artificial wetland which is mainly characterized in that a mud-water separator is arranged in a rinsing flow of an undercurrent artificial wetland, wherein a water inlet pipe and a distribution well are arranged at one end of the artificial wetland, the main part is a layered filler matrix, plants are planted on the surface of the wetland above the filler matrix, sewage enters into the filler matrix of the undercurrent artificial wetland through at least one water distribution port or water distribution pipe, at least one mud-water separator is arranged in the process where sewage flows through the filler matrix of the artificial wetland, the mud-water separator is provided with a cleaning exhaust channel, a water collecting pipe is arranged at the rear end of the rinsing flow of the artificial wetland, the water collecting pipe is connected with a well at the tail end, and an outward discharge pipe is arranged on the side wall of the well. The mud-water separating artificial wetland can dredge and deblock the artificial wetland, thereby facilitating operation of the artificial wetland in a steady working condition.

Description

technical field [0001] The invention relates to a sewage treatment method and device. Background technique [0002] Constructed wetland is a traditional sewage treatment technology. The matrix filler of wetland can intercept pollutants, but as time goes on, pollutants accumulate, and the constructed wetland will be clogged, affecting the effect and operation. The clogging problem of constructed wetlands is also the main factor that plagues the application of constructed wetlands. As long as there is pollutant input, it will inevitably accumulate over time. Therefore, one way to overcome and reduce the clogging problem is to find a way for the accumulated pollutants output path. Based on this idea, the technical logic of state control is adopted to design a mud-water separator in the constructed wetland, which can realize the separation and output of sludge, thereby reducing the clogging factor of the constructed wetland and ensuring that the constructed wetland is in a stab...
