Problems solved by technology

[0010] The technical problem to be solved in the present invention is to modify the surface of the original adsorbents for the defect that the affinity of the emulsified oil beads is not strong, and generate a film with a strong affinity for oil on the surface, thus improving It increases its adsorption capacity for oil, reduces the concentration of oil in the adsorbed water, and enhances the adsorption effect.

Embodiment Construction

[0022] In the following performance tests of the examples, imported oily sewage with an oil content of 70mg / l and a water temperature of 20°C was used. The test of the oil content in the water carried out the UV spectrophotometry in the "Water and Wastewater Monitoring and Analysis Method" compiled by the State Environmental Protection Administration. Law.

[0023] 1. First prepare 1000g of simethicone emulsion with a mass concentration of 0.01%, then mix 999.9g of diatomaceous earth and simethicone emulsion in a container, and stir thoroughly. Put the mixture in a tray, spread it out, put it into an oven, and bake it at 50°C for 24 hours. After drying, take it out, break up the agglomerates, and pass through a 40-mesh sieve to obtain a powdery modified diatomite adsorbent. Using this adsorption device for two-stage series test, the results are shown in the table.

[0024] 2. First prepare 1000 g of simethicone emulsion with a mass concentration of 10%, then mix 900 g of dia...

Abstract

A modified adsorbent for adsorbing oil from water features that the organic silicon substance chosen from sodium methylsilicate, methyl silicon oil, phenyl silicon oil, methylethyl silicon oil, ethyl oil, hydrogen contained methyl silicon oil, etc is used to modify the surface of the adsorbent chosen from montmorillonite, bentonite, diatomite, pearlite, powdered coal ash, etc to generate a lipophilic film layer, so increasing its oil adsorptivity.

Description

technical field [0001] The invention relates to an adsorbent capable of adsorbing oil in oily sewage. Specifically, it is a modified adsorbent that can absorb oil in water, which is produced by modifying the adsorbent series of materials with organic silicon series materials. [0002] The organosilicon series substances mentioned in this article have a linear molecular formula of [0003] The molecular formula with branches is [0004] [0005] Where R is an organic group, and n and m represent the number of chain segments. Such as sodium methyl silicate, methyl silicone oil, phenyl silicone oil, methyl ethyl silicone oil, methyl hydrogen silicone oil, ethyl silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl hydroxy silicone oil, Base trifluoropropyl silicone oil, methyl vinyl silicone oil, ethyl hydrogen silicone oil, hydroxyl hydrogen silicone oil, cyano silicone oil. It can be one of them, or a combination of several of them. The co...
