Deep-bed wetland programmed stepped water distributing device

Abstract

The invention discloses a deep-bed wetland programmed progressive water-distributing device, which consists of middle control machine and on-line monitor, wherein the middle control machine connects on-line monitor and one or more electric valve separately; the probe of on-line monitor extends in the inlet, outlet and wetland water-distributing segments to monitor the index, which transmits these indexes to middle control machine to control one or more electric valve to adjust the flow of pipe; the fill depth of wetland is 80-100cm.

Description

technical field [0001] The present invention relates to a wetland. Background technique [0002] Ladder water distribution is an existing water distribution method in constructed wetlands. Sewage enters the wetland in stages from the head end and the middle and rear. The dissolved oxygen needed and the carbon source needed for denitrification can enhance the denitrification effect of the wetland. However, due to the absence of automatic control and monitoring equipment, manual collection and monitoring of water samples is required, with a heavy workload and long intervals between collection of water samples, which cannot timely reflect the water quality of the inflow and outflow and different water distribution ends, as well as the sediment and density of the packing layer. Biomass can not automatically adjust the ratio of influent series and flow ratio, which has a large blindness. [0003] Based on years of engineering experience, the US National Environmental Protection...

AI Technical Summary

Problems solved by technology

Due to the shallow depth of the traditional wetland bed and the small hydraulic load per unit area, the wetland occupies a large area, which hinders the large-scale promotion and application of constructed wetlands.
