Description
Technical field
The invention belongs to environmental monitoring, environmental improvement and Computer Control Technology field, and in particular to a kind of suspension
Agitation and filtration concentrates acquisition control system and method.
Background technology
With industrialization, the deep development of urbanization, the demand of central water supply is increasing, while water head site water quality
Criterion of acceptability more and more higher.Suspension refers to be suspended in the solid matter in water, including inorganic matter insoluble in water, organic
Thing and silt particle, clay, microorganism etc., suspension content is one of index for weighing water pollution degree in water, is released lake endogenous
Put and important role is play in hydro-environmental change.In general, the cellular structure of suspension makes its absorption substantial amounts of dirty
Thing and nutrient are contaminated, the wherein content of nutritive salt, heavy metal and toxic organicses may be higher several times than in deposit,
It is the hundred times of water body solubilised state, along with the release of nutrient in the decomposition, condensation process in suspension, water body can be made
Loads of nutrition increase, aggravates body eutrophication.The increase of concentration of suspension simultaneously is to cause the decline of lake water transparency and optics
The main reason for attenuation coefficient increases, the presence of Suspended Matter in Water can influence water body water colour, increase the decay to light radiation,
So as to reduce water transparency, and then change Underwater Optical and shine intensity distribution, influence lake region phytoplankton photosynthesis and primary life
Force of labor is horizontal.Species, the content of pollutant in the distribution characteristics, influence factor and suspension of water body recovery technology concentration are studied,
For improving water transparency, improve aquatic ecosystem, verify in aquatic ecosystem the Transport And Transformation of pollutant and and its
Associated ecological effect, control body eutrophication have important practical significance.
Because suspended particulate matter concentration is typically small in natural water body, aperture, fractal dimension for Suspended Matter in Water
Deng physical features, a small amount of water sample can be gathered and then observed under the microscope, but want pollutant in Suspended particulates
Content, species and form, it is necessary to which analysis test could be carried out by obtaining the suspension of sufficient amount, effective, conveniently
Suspension sample collection method and collection device, it is the basis for studying water body recovery technology.The acquisition mode of suspension is main at present
There are two kinds.The first is that the glass fibers that use for laboratory dries processing of weighing in advance are taken back after gathering water sample with hydrophore at the scene
Filter paper filtering is tieed up, drying is weighed, and obtains suspension gross weight.This method is typically every for the relatively low water body of suspension content
Individual sampled point needs collection 5-10L water samples, and the detection of low concentration and trace materials even needs liter more than 100, and multiple
The cumulative volume of the cumulative water sample in sampling location may also reach hectolitre, and sampling process is cumbersome to need substantial amounts of artificial behaviour
Make, the water sample quantity of collection is more, weight is big, not portable, and the sampling period is grown.Second will be specified under water by immersible pump
The water sample of opening position is drawn into sampling boat or bank carries out filtration in-situ.Because the suspension in filtering water body needed to use
Device, vavuum pump and kinds of experiments equipment are filtered, sampling location bad environments, does not possess experiment condition, operating difficulties, and mistake
It is slow to filter device filtering, a sampled point, which collects enough suspensions, just to be needed to consume the plenty of time, in this way in area
The sample collection for wanting to complete whole sampled points on wide lake, reservoir is unpractical.
Patent of the present invention is by " state natural sciences fund instrument basis special project-water source Reservoir Water Quality multidimensional pressure tight sampling
The subsidy of items of equipment (51327004) ".
