Description
Technical field
The present invention relates to a kind of detection method of suspension content, and in particular to the control of suspension content in sewage disposal
Characterization processes.
Background technology
Suspension (Suspended Solids) refers to the solid matter being suspended in water, including insoluble in water inorganic
Thing, organic matter and silt particle, clay, microorganism etc..Suspension content is one of index for weighing water pollution degree in water.Suspension
It is the main reason for causing water muddiness.Easy anaerobic fermentation after organic suspended matter deposition in water body, makes water quality deterioration.Chinese sewage
Comprehensive discharge standard points 3 grades is, it is specified that the highest of suspension allows concentration of emission, Chinese groundwater quality mark in sewage and waste water
Accurate and standards for drinking water quality dictates to suspension in water by index of turbidity.
And in the prior art, suspension refers to by the solids of filter the filter paper to constant weight can not will be claimed to be put into Bu Shi
In funnel, water sample is filtered with middling speed quantitative filter paper, constant weight is dried to through 103~105 DEG C, the obtained residue that can not always filter (suspends
Thing) content.Specifically detection mode is：
Suspension in water quality refers to that water sample by the filter membrane that aperture is 0.45 μm, is trapped on filter membrane and in 103~105
DEG C it is dried to the material of constant weight.The uneven solid matter of floating or submergence is not belonging to suspended material, should be removed from water sample.It is existing
It is typically first to remove in water sample after the uneven solid matter of floating or submergence to have in technology, the suspension in water quality is carried out
Detection, operating process is cumbersome, causes detection intensity big.
The content of the invention
The technical problems to be solved by the invention are：The detection operating process of suspension is cumbersome in the prior art, causes to examine
Survey intensity it is big the problem of, and it is an object of the present invention to provide in sewage disposal suspension content control characterization processes, can effectively reduce operation
Step, and testing result is effectively ensured, effect is more notable.
The present invention is achieved through the following technical solutions：
The control characterization processes of suspension content in sewage disposal, including：

For 0.2um, the filtering accuracy of the second screen pack is 10nm；
Second screen pack is placed into drying box and dried repeatedly until the adjacent weight difference measured twice is less than or equal to
0.1mg, and obtain the weight t1 of the second screen pack；Second screen pack is installed in isolating device；
(2) sewage sample is added, the volume V of sewage is read according to the scale on conical flask body, isolating device is inverted, makes dirt
Water flows through the second screen pack until sewage filters completely；
(3) distilled water is added to concussion in conical flask body and rinses conical flask body, being then inverted flows completely through distilled water
Conical flask body is flowed out after second screen pack；
(4) after repeat step (3) 2~4 times, the second screen pack is removed, is placed into drying box and dries repeatedly until adjacent
The weight difference measured twice is less than or equal to 0.1mg, and obtains the weight t2 of the second screen pack；
(5) the content H of suspension is obtained according to calculation formula, the content H of suspension calculation formula is：H=(t2-
t1)/V。
By the optimization of the device of the present invention, the step of can effectively simplifying operating method, dress of the invention need to be only used
Put and once filtered, then detect the weight increase situation of the second screen pack, you can effectively calculate the content of suspension, behaviour
Make easier.And the mode in the present invention can be effectively isolated the uneven solid matter for floating or submerging in boiling water sample, make to hang
The testing result of float is more accurate.
Further, the screen pack installing matrix top is provided with first annular protruding part, and second screen pack passes through
One ring packing packing ring is fixed on first annular protruding part.The conical flask body top is provided with the second annular protruding part, should
First screen pack is fixed on the second annular protruding part by the second ring packing packing ring.
By the setting of said structure, the amount of suspension adhesion in a device is reduced as far as possible, makes it viscous as far as possible
It is attached on screen pack, and then effectively improves the accuracy of testing result.
Preferably, the first annular seal washer and the second ring packing packing ring are formed by quality of rubber materials, and this first
The girth of ring packing packing ring under field conditions (factors) is less than or equal to the girth of first annular protruding part, the second ring packing packing ring
