Constructed wetland sewage discharge monitoring device

Abstract

The invention relates to the technical field of constructed wetlands and discloses a constructed wetland sewage discharge monitoring device comprising a discharge pipeline, a monitoring cavity is formed above the discharge pipeline, a sound transmission hole is formed in the inner wall of the upper side of the monitoring cavity, an alarm is arranged below the sound transmission hole, an L-shaped plate is fixedly connected to the left side of the alarm, and a trigger is fixedly connected to the upper portion of the left side of the L-shaped plate. According to the constructed wetland sewage discharge monitoring device, on the basis of the formula: Ffloating = rho liquid * g * Vdischarge, the higher the density is, the higher the buoyancy is; a floating ball is subjected to upward buoyancy,so that an insulating block is pushed to move upwards, and a second metal block moves upwards along with the insulating block and thus a second spring is compressed, the spring force of the second spring acts on a movable rod, the first metal block touches the trigger, and the alarm gives out alarm sound; the alarm sound is transmitted out through the sound transmission hole, and the effects of simple structure, easy later maintenance, low failure rate and low energy consumption are achieved.

Description

technical field [0001] The invention relates to the technical field of constructed wetlands, in particular to a sewage discharge monitoring device for constructed wetlands. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially constructed and operated under control. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. When sewage and sludge flow in a certain direction, they are mainly used It is a technology for treating sewage and sludge through the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. Its mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrient absorption, and the action of various animals. After the treatment of artificial wetlands, the treated sewage is discharged for fa...
