Efficacy test
The synergist prepared using embodiment 2,3,4 and comparative example 3 as test object, test its remove sewage middle and high concentration it is non-from The effect of sub- surfactant.
Test method are as follows: using the cleaning liquid of certain stainless steel cleaning factory, it is known that in the sample containing it is a large amount of it is non-from Sub- surfactant causes the electrostatic neutralization of PAC that can not play effect since nonionic surfactant micelle is not charged Fruit can not make haze reduction.So in this experiment, using turbidity variation as the mark of the removal effect of nonionic surfactant Will.Turbidity is tested using UV-visible spectrophotometry.
Experimental group 1: the synergist prepared using embodiment 2, PAC+ synergist+PAM processing.
Experimental group 2: synergist prepared with embodiment 3, PAC+ synergist+PAM processing are adopted.
Experimental group 3: the synergist prepared using embodiment 4, PAC+ synergist+PAM processing.
Control group 1: the synergist prepared using embodiment 2 is only added synergist and is handled.
Control group 2: adopting synergist prepared with embodiment 3, only adds synergist and is handled.
Control group 3: the synergist prepared using embodiment 4 is only added synergist and is handled.
Control group 4:PAC+PAM processing.
Control group 5: the synergist prepared using comparative example 3, PAC+ synergist+PAM processing.
Shown in test result is as follows table 1 and Fig. 1~5.Wherein Fig. 1 is the effect that synergist processing is not used, wherein left figure For untreated sewage sample, right figure is treated the effect of control group 4；Fig. 2 is the effect handled using synergist, wherein left Figure is untreated sewage sample, and right figure is treated the effect of experimental group 1, it can be seen that after processing, it is non-in sewage Ionic surface active agent is condensed into cotton-shaped alum slag, and directly filtering can remove cotton-shaped alum slag, and filtered sewage is as clear as crystal；Figure The synergy for being followed successively by untreated sewage sample in 3 from left to right, being prepared through PAC+PAM processing (i.e. control group 4), embodiment 2 Agent handles the result of the synergist+PAC+PAM processing (i.e. experimental group 1) of (i.e. control group 1) and the preparation of embodiment 2 (due to experiment The effect of group 1,2 and 3 is suitable, therefore only provides the treatment effect figure of experimental group 1), as can be known from Fig. 3, only with the present invention When the synergist or PAC+PAM of preparation, the nonionic surfactant in sewage can not be precipitated；And work as increasing of the present invention When effect agent and PAC, PAM are used cooperatively, it can be very good the nonionic surfactant in precipitating sewage, reduce the turbid of sewage Degree.Fig. 4 is treated the effect of control group 5, it can be seen that the synergist prepared through reference examples 3 is used cooperatively with PAC, PAM When, a part of nonionic surfactant can be precipitated, but ineffective, its turbidity of treated sewage is still very high, with Only with PAC+PAM, treated that effect is suitable in control group 4.Fig. 5 is raw sewerage and treated through experimental group 1 Comparison diagram after sewage water filtration, wherein left figure is the effect picture of raw sewerage filtering, and right figure is after the processing of experimental group 1 Sewage water filtration effect picture, from the comparison of two width figures it is found that filtering out cotton-shaped alum slag through treated the sewage of experimental group 1, Sewage is as clear as crystal, and nonionic surfactant therein almost removes.
The sewage to be measured of table 1 before treatment after turbidity comparing result
It is found that only high concentration ought be contained with PAC+PAM processing with synergist prepared by the present invention or only from table 1 and Fig. 1~3 When the sewage of nonionic surfactant, the nonionic surfactant in sewage, after processing, sewage can not be removed well Turbidity there is no too big variation, it is dirty after processing and when synergist and PAC, PAM prepared by embodiment 1 to 3 is used cooperatively The turbidity conspicuousness of water reduces, and turbidity is only 1/10th or so before handling, and treated, and sewage is as clear as crystal, table When bright synergist of the present invention and PAC, PAM are used cooperatively, the nonionic surfactant in sewage, effect can be effectively removed Significantly, can extensive mass processing nonionic surfactant containing high concentration sewage, it is living to reduce non-ionic surface in sewage Property agent discharge amount, reduce pollution and destruction of the nonionic surfactant to environment, be conducive to the protection of environment.
After from the comparison of experimental group 1~3 and control group 4, control group 5 it is found that control group 4 and control group 5 handle, sewage Turbidity is suitable, shows the synergist not prepared according to the method for the invention, when being used cooperatively with PAC, PAM, does not show Synergistic effect is not suitable for the purified treatment of the nonionic surfactant containing high concentration in sewage.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than protects to the present invention The limitation of shield range can also be made on the basis of above description and thinking for those of ordinary skill in the art Other various forms of variations or variation, there is no necessity and possibility to exhaust all the enbodiments.It is all of the invention Made any modifications, equivalent replacements, and improvements etc., should be included in the protection of the claims in the present invention within spirit and principle Within the scope of.
