Abstract
The invention discloses a detection method for the content of suspended solids in wastewater. The detection method particularly comprises the following steps: sampling and preparing a filter membrane. The method can rapidly and accurately detect the content of the suspended solids in wastewater.
Description
Technical field
The invention belongs to physical and chemical inspection technical field, relate in particular to the detection method of suspension content in a kind of sewage.
Background technology
Suspension refers to be suspended in the solid matter in water, comprises inorganics, organism and silt particle, clay, microorganism of water fast etc.In water, suspension content is one of index of weighing water pollution degree.Suspension is the main cause that causes water muddiness, and easy anaerobic fermentation after the organic suspended matter deposition in water body, makes water quality deterioration.
Summary of the invention
The object of the invention is to overcome the defect of prior art, the detection method of suspension content in a kind of sewage is fast and accurately provided.
For achieving the above object, the present invention proposes following technical scheme: the detection method of suspension content in a kind of sewage, is characterized in that: specifically comprise the steps:
A. sampling: select polyethylene bottle or Pyrex bulb to clean with washing agent, then use successively tap water and distilled water flushing clean, and gather water sample with after the water sample cleaning gathering three times, cover tightly bottle stopper;
B. filter membrane is prepared: with the Smooth forceps sub-folder of twitching one's mouth, get in the measuring cup that filter membrane is put in prior constant weight, move into baking oven takes out to be placed in and in exsiccator, is cooled to room temperature after 103 ~ 105 ℃ dry 0.5h, claim its weight, oven dry repeatedly, cooling, weighing, until the weight difference of twice weighing is less than or equal to 0.2mg, be correctly placed on the filter membrane of constant weight on the filter membrane pallet of membrane filter, add a cover supporting funnel, and fix with clip, with the moistening filter membrane of distilled water, and continuous suction strainer;
C. measure: measure the sample 100ml suction filtration fully mixing, make moisture all pass through filter membrane, again with each 10ml distilled water continuous washing three times, continue suction strainer to remove traces of moisture, stop after suction strainer, the filter membrane that careful taking-up is loaded with suspension is placed in the measuring cup of former constant weight, move in baking oven, after 103 ~ 105 ℃ dry 0.5h, to take out to be placed in and in exsiccator, be cooled to room temperature, claim its weight, oven dry repeatedly, cooling, weighing, until the weight difference of twice weighing is less than or equal to 0.4mg;
D. calculate: according to above-mentioned value, calculate suspension content in sewage.
In described step b, the aperture of filter membrane is 0.45 μ m, diameter 45 ~ 60mm.
In described steps d, the computing formula of suspension is:
The expression C of suspension content=
In formula, the concentration of suspension in C-water, mg/L;
V-volume of sample, ml;
The weight of A-suspension+filter paper, g;
The weight of B-filter paper, g.
In described step b, membrane filter is full glass nuclepore membrane filter.
Compared with prior art, the detection method of suspension content in disclosed a kind of sewage, the method can fast, accurately detect suspension content in sewage.
