Description
Technical field
The invention belongs to the environmental monitoring technology field, relate in particular to a kind of with current Buffer Pool, tube settler, horizontal sedimentation tank, solid-liquid separator, filtrator, multichannel rinse water arrangement, by the computing machine central controller, fluctuation changes according to river silt content value, and control combination can realize the heavily silt-carrying river automatic water quality monitoring water sample pretreatment system of multiple water sample work of treatment pattern automatically.
Background technology
Still blank aspect rocky (Gao Hansha) water quality of river monitoring water sample silt pretreatment system equipment both at home and abroad at present, same category of device only is only applicable to general common non-high silt-laden river and river silt content fluctuation range is less, the water quality monitoring water sample silt pretreatment unit of simple, semi-automatic, non intelligentization of single mode of operation, means only at present.The difference of high silt-laden river and non-high silt-laden river mainly contains 2 points, the high silt-laden river silt content of first height, every cubic metre of river silt content can reach more than hundreds of kilograms when high, its two be high silt-laden river silt content in different sections, different values in season differs greatly, when the section silt content that has as high silt-laden river was low, every cubic metre of river silt content only was less than 1 kilogram.So, when being used for high silt-laden river water quality monitoring water sample disposal system and requiring to possess the high sediment concentration of processing river, silting can not take place to be stopped up, and possess adapt to the silt content fluctuation range big, can select the different effective and economic mode of operation abilities of combination according to the silt content value scope of different sections, Various Seasonal.Domestic and international existing water quality of river monitoring water sample treating apparatus because it only has single mode of operation, is formed simply, can't be used for high sediment concentration, river that silt content value fluctuation range is big.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and provide a kind of and possess when handling the high sediment concentration river, silting can not take place to be stopped up, and possess adapt to the silt content fluctuation range big, can be according to the silt content value fluctuation range of different sections, Various Seasonal, select the heavily silt-carrying river automatic water quality monitoring water sample pretreatment system of the different effective mode of operation of combination, be applicable to that Gao Hansha, the water quality of river that the silt content fluctuation range is big monitor the processing of water sample automatically.
The object of the present invention is achieved like this: comprise the computing machine central system controller, be arranged on the submersible pump in the river, the submersible pump that is arranged in the river is connected by pipeline and current Buffer Pool, the bottom of current Buffer Pool is connected with the inclined tube settling tank that has installed detachable inclined tube, the top spilling water of inclined tube settling tank is along communicating with the advection settling tank, the advection settling tank passes through valve, pressure pump and solid-liquid separator and pipeline and intermediate water tank are connected, intermediate water tank passes through valve, pressure pump, filtrator, pipeline and sample water tank are connected, and the sample water tank is again through the instrument water pump, valve and monitoring instrument are connected.Clean the top that the water source is arranged on pipeline by electrically operated valve current Buffer Pool, inclined tube settling tank, advection settling tank, intermediate water tank and sample water tank respectively, clean the water source and by electrically operated valve pipeline is arranged on the bottom of current Buffer Pool, inclined tube settling tank, advection settling tank, intermediate water tank and sample water tank respectively again, clean the water source and be connected by valve and underwater monitoring instrument automatic flushing device again.The sample water tank is connected with automatic sampler by valve again.
The present invention has the ability of the high sediment charge river of very strong processing, and the river that extracts is carried out multistage continuous processing, and each grade adopts different physical methods to handle the silt of various particle diameters, makes in the sample water after the final processing sediment grain size less than 5 microns.The first order of water treatment system is a buffer zone, and submersible pump draws up the river that comes and tends to stable here, and oarse-grained silt sinks; The second level is tube settler, and its high efficiency precipitation function makes most of 100 microns sand grain be precipitated removal; It is that according to sedimentation theory, the effect of precipitation is relevant with desilting area and settling height that the present invention adopts the reason of tube settling in first order sedimentation; Tube settler designs in view of the above, and it has increased desilting area for horizontal sedimentation tank, has reduced the precipitation height, thereby has improved sedimentation effect.The silt content of river generally all can have significantly raising in flood season, in the set time, (be generally half an hour), not enough situation may appear precipitating in advection sedimentation, and the filtrator of next stage is applied unnecessary working pressure, influences the long-term no maintenance operation of filtrator.Because the high advection sedimentation several times of filter effect of tube settling are not easy to occur precipitating not enough phenomenon.The third level is an advection sedimentation, continues to remove the less silt of particle; The fourth stage is available solid-liquid separator, utilizes the centrifugation of eddy flow that unwanted solid matter is discharged with the elimination factor of maximum; Level V is a disc filter, and its special structure design can be removed the sand grain greater than 5 microns, and through above processing, silt and the suspension of giving the water sample of on-line instrument detection meet the requirements fully.
The present invention can remove silt effectively through repeatedly experiment showed,, water sample silt content after treatment is less than 0.2kg/m
3Reached according to national industry and stipulated about the water sample preconditioning technique, silt pretreatment system running parameter rationally is set, and select Gao Hansha, medium sand and general river, three kinds of mode of operations of river of containing automatically with the seasonal variations rule according to river silt content value fluctuation, be applicable to Gao Hansha, silt content with seasonal variations difference range big river and the generally sample water supply of the automatic water quality monitor device in river, water sample after treatment can not change the composition and the character of its measured parameter.The present invention is fit to the characteristics of the Yellow River high concentration of sediment, and has preferable quality, higher performance, and lower operating cost is easy to install, and is easy to safeguard.
In the middle of the process of water treatment, after a test loop finished, system can automatically take turns to wash to each water tank with the press water that cleans, and the silt that will accumulate is rinsed well, and the silt that prevents to stop up and avoid accumulating is to the interference of test next time.The user can also start independent cleaning procedure according to actual needs, and each link of water treatment portion and the multi-parameter monitoring instrument of directly throwing in the river are washed completely.
