Problems solved by technology

But it is not that the larger the molecular weight of the polymer, the better the flocculation effect. If the molecular weight is too large, the flocculation speed is too fast, which will cause the suspension of fine particles to remain in the supernatant
In addition, the molecular weight is too large, the water solubility of the polymer becomes poor, and it is not easy to disperse and dissolve in water, which is not conducive to flocculation

Embodiment

[0041] The method for testing the influence of salt concentration on the flocculation effect of the hydrophobic polymer flocculant involved in the present invention, its specific steps are as follows:

[0042] (a) prepare a hydrophobic polymer flocculant sample;

[0043] (b) preparing clay suspensions of different salt concentrations;

[0044] (c) Add the clay suspensions of equal amounts of different salt concentrations into different test containers respectively, and adjust to the same pH value;

[0045] (d) adding an equal amount of hydrophobic polymer flocculant in the clay suspension;

[0046] (e) Stand for a period of time, and compare the light transmittance by observation, so as to obtain the influence of salt concentration on the flocculation effect of the hydrophobic polymer flocculant.

[0047] In the step (c), the test container is a beaker.

[0048] In the step (c), the pH value is 7.

[0049] In the step (c), the pH value of the clay suspension is adjusted by...

Abstract

The invention discloses a method for testing influence of salinity on flocculation effect of a hydrophobic polymeric flocculant. The method comprises steps of: preparing a polymeric flocculant and clay suspending liquids with different salinities; adding the clay suspending liquids with different salinities in a same volume respectively into different test containers and adjusting to a same pH value; adding hydrophobic polymeric flocculant of a same volume into the clay suspending liquids; standing for a while and comparing light transmittances through observation, so as to obtain influence of salinity on flocculation effect of the hydrophobic polymeric flocculant. The invention can rapidly test influence of salinity on flocculation effect of a hydrophobic polymeric flocculant, has high test accuracy, simple operation steps and low test cost, so as to select hydrophobic polymeric flocculants according to different sewage and enhance treatment effect of hydrophobic polymeric flocculants.

Description

technical field [0001] The invention relates to a method for testing the effect of salt concentration on the flocculation effect of a hydrophobic polymer flocculant. Background technique [0002] With the rapid development of economy and the continuous increase of population, the environmental problems caused by energy production and consumption are becoming more and more serious, especially the problem of water pollution has become a hot issue that is widely concerned by all walks of life. Among many urban sewage and industrial wastewater, oily wastewater from the petroleum industry is the most representative. In order to improve the treatment efficiency of oily wastewater, a variety of sewage treatment agents have been developed and produced, including coagulants, flocculants, flotation agents, etc. Among them, the hydrophobic polymer flocculant is used as an efficient water treatment agent, which can speed up the purification of water and remove suspended solids and toxi...
