SU638356A1 - Sorbent for purifying waste water from mechanical impurities - Google Patents

Description

one

The invention relates to the composition of the sorbent and can be used to extract mechanical impurities.

A sorbent for the treatment of waste water from mechanical impurities, consisting of porous balls of synthetic polymer I, is known.

In addition, a sorbent for the treatment of wastewater from mechanical impurities, in particular activated silicon f2, is known.

However, such sorbents do not provide a high degree of purification.

The closest to the invention to the technical essence and achievable result is a sorbent, including synthetic granular material, in particular, Sipron z.

However, this sorbent does not provide a high degree of wastewater treatment from mechanical impurities.

The purpose of the invention is to increase the degree of wastewater treatment from mechanical impurities.

This is achieved by adding to the known sorbent

heavy hydrocarbons in the following ratio, wt.%:

Synthetic granular material 90-99

T hydrocarbons1-10

The sorbent is prepared by passing heavy hydrocarbons through synthetic granular material under dynamic conditions.

Example. Through a layer of sorbent containing 90 wt.% Synthetic granular material and 10 wt. heavy hydrocarbons, pass wastewater contaminated with mechanical impurities with a concentration of 300 mg / l at a rate of 10 ml / min. In purified water, according to chemical analysis, the content of mechanical impurities decreases from 300 mg / l to 7 mg / l.

The table presents comparative data on the degree of water purification by the known and proposed sorbent.

Claims (2)

As can be seen from the obtained data, the prevalence of the VJ sorbent increases the volume of wastewater treatment from mechanical impurities from 300 mg / l to 720 mg / l, as compared with the known, which allows reducing the content of impurities from BbO to 50-80 mg / l . Claims of the Invention A sorbent for the purification of waste water from mechanical impurities, including a synthetic granular material, characterized in that, in order to increase the degree of purification, it also contains heavy hydrocarbons in the following ratio, wt.%; Synthetic granular material 90-99 Heavy coal 1–10 hydrogens Sources of information taken into account during the examination: 1.
