Water sample pre-treatment system for automactically monitoring sandy river water quality

Abstract

The present invention relates to a water quality automatic monitoring water sample pretreatment system for sandy rivers which realizes multiple water sample processing working modes by computer, which comprises a computer central controller and a submersible pump in the river. The bottom of the flow buffer tank is connected to the inclined tube settling tank, the overflow edge of the inclined tube settling tank is connected to the advection settling tank, the advection settling tank is connected to the intermediate water tank by valves, pressurized water pumps and solid-liquid separators, the intermediate water tank is connected by valves, The pressurized water pump, filter, and pipeline are connected to the sample water tank, the sample water tank is connected to the monitoring instrument, and the sample water tank is connected to the automatic sampler through the valve, which can effectively remove the sediment and set the system working parameters reasonably. The sample water supply for the automatic water quality monitoring instrument of the river with a large range of variation in the amount of sand with the seasons.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and particularly relates to a water flow buffer tank, an inclined tube sedimentation tank, an advection sedimentation tank, a solid-liquid separator, a filter, and a multi-channel flushing water device, through a computer central controller, according to the sand content of the river Quantity fluctuations and changes, the control combination can automatically realize a variety of water sample processing working modes of the sandy river water quality automatic monitoring water sample pretreatment system. Background technique [0002] At present, there is still a blank in the water quality monitoring water sample sediment pretreatment system equipment of sandy (high sand content) rivers at home and abroad. At present, similar equipment is only suitable for ordinary non-high sand content rivers and the fluctuation range of river sediment content is small. On...

AI Technical Summary

Problems solved by technology

The existing river water quality monitoring water sample processing devices at home and abroad, because they only have a single working mode and simple composition, cannot be used in rivers with high sediment concentration and large fluctuation range of sediment concentration.
