Description
Technical field
The present invention relates to a kind of method, more particularly, to a kind of side that accurately can be measured to suspension in water quality
Method.
Background technology
Suspended material refers to the solid matter being suspended in water, including inorganic matter insoluble in water, organic matter and silt particle, glutinous
Soil, microorganism etc..Suspension content is one of index for weighing water pollution degree in water.Suspension is cause water muddy main
Reason.Easy anaerobic fermentation after organic suspended matter deposition in water body, makes water quality deterioration.3 grades of Chinese integrated wastewater discharge standard point,
Defining the highest of suspension in sewage and waste water allows concentration of emission, Chinese groundwater quality standard and Drinking Water health
Standard dictates to suspension in water by index of turbidity.Suspended material in water be particle diameter about 10-4mm with
On particulate.It is visually visible.These particulates are mainly by silt, clay, protozoan, algae, bacterium, virus and high score
Sub- organic matter etc. forms, and is usually suspended among current, turbid phenomenon caused by water, is also all as caused by this class material.Water
Middle impurity can be divided into three classes by its granular size：The maximum referred to as suspension of particle, is secondly referred to as colloid substances, minimum is molecule
It is referred to as dissolved matter with ion.Above-mentioned impurity can be transported if unprocessed or dealing with improperly and enter boiler to the safety economy of boiler
Row brings various harm.The suspension needs contained in water quality are measured, to determine whether water quality meets people's life requirement,
The method efficiency of existing measure suspension is low, and the error determined is very big, and people damage after drinking to body.
The content of the invention
It is an object of the invention to overcome the method efficiency of above-mentioned existing measure suspension low, and determine the error come
Very greatly, the problem of people damage after drinking to body, devise one kind accurately can be measured to suspension in water quality
Method, the principle of this method is easy, can determine the suspension value volume and range of product in water quality exactly, whether determine water quality
Meet human body standard for drinking, protect the health of people, solve it is existing measure suspension method efficiency it is low, and determine
The problem of error out is very big, and people damage after drinking to body.
The purpose of the present invention is achieved through the following technical solutions：It is a kind of accurately suspension in water quality to be measured
Method, comprise the following steps：
（1）Sampling：Polyethylene bottle used is cleaned with detergent, then clean with running water and distilled water flushing successively, is being sampled
Before, then with the water sample that will be gathered clean three times, the uneven solid matter of floating or submergence is not belonging to suspended material, Ying Cong
Being removed in water sample, the water sample of storage of samples collection should analyze measure as early as possible, such as need to place, should be stored in 4 DEG C of refrigerating boxes, but most
Length must not exceed seven days, it is impossible to any protective agent be added, with partition equilibrium of the tamper-proof material between solid, liquid；
（2）Continuous mode：Middling speed quantitative filter paper is gripped with tweezers, moves into baking oven after drying half an hour in 103~105 DEG C and takes out
Put and room temperature is cooled in drier, claim its weight, dry, cool down, weigh repeatedly, until the weight difference≤0.2mg weighed twice,
The middling speed quantitative filter paper of constant weight is folded and is put into funnel, is put into triangular flask, is measured and be sufficiently mixed uniform sample 50mL mistakes
Filter, moisture is set all by filter paper, after stopping filtering, to move into baking oven after being dried one hour at 103~105 DEG C and move into out,
Make to be cooled to room temperature, claim its weight, dry, cool down, weigh repeatedly, untill the weight difference≤0.4mg weighed twice, filter membrane
The excessive suspension of upper retention may carry excessive moisture content secretly, in addition to drying time is extended, it is also possible to cause filtration difficulty, meet this
Situation, it can take the circumstances into consideration to materials less, suspension is very few on filter membrane, then can increase weighing error, influences measurement accuracy, if necessary, can
Increase volume of sample, with 5~100mg suspensions object amount as the usage range for measuring volume of sample；
（3）As a result calculate：Suspension content C (mg/L) is calculated as follows：
C=(A-B)*106/V
In formula：C --- concentration of suspension in water, mg/L；
A --- suspension+filter paper, g；
B --- filter paper, g；
V --- volume of sample, mL.
In summary, the beneficial effects of the invention are as follows：The principle of this method is easy, can determine exactly in water quality
Suspension value volume and range of product, determines whether water quality meets human body standard for drinking, protects the health of people, solves existing survey
Determine that the method efficiency of suspension is low, and determine the problem of error come is very big, and people damage after drinking to body.
Embodiment
With reference to embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited only to
This.
