Abstract

1. СПОСОБ ОЧИСТКИ ПРИРОДНЫХ И СТОЧНЫХ вод коагул цией алюминнйсодержащим реагентом, о т л и ч а rent и и с   тем, что, с целью повышеНИН степени очистки, в качестве алюкинкйсодержаа{его реагента используют высококислотный катионит в алюми1шевЬй форме и процесс ведут в присутствии низкоосновного ашюнита в гидроксильной форме. 2. Способ по п. 1,отличающ и и с   тем, что кат онит и ан онит ввод т в соотн«вении объемных емкостей 1:2-4 соответственно.1. METHOD FOR CLEANING NATURAL AND WASTE WATER BY COAGULATION BY ALUMINUM-CONTAINING REAGENT, take care of the fact that, in order to increase the degree of purification, high-acid cationite in aluminum form is used as alumina-containing reagent and aluminum process is conducted in the presence of low-base ashyunite in hydroxyl form. 2. The method according to claim 1, is also distinguished by the fact that the cat onite and anonit are introduced in a ratio of bulk containers of 1: 2-4, respectively.

Description

сл сcl

ОР 00 00 1 Изобретение относитс  к способам очистки, природных и сточных вод и может быть использовано в процессах водоподготовки и дл  очистки сточных вод в киническрй, нефтехимической и др. отрасл х промышленности , Цель изобретени  - повышение ста пени очистки природных и сточных вод. Примеры 1-5. В лабораторный стакан наливают 1 л воды, имеющей следук Е е показатели качества: цветность 182 град. ПКШ; мутность 6,8 мг/л; содержание железа о,211 мг/л; солесодержание 108 мг/л; рН 7,3. К воде добавл 83 ют смесь, содержащую твердофазный катионит марки КУ-2-8 с обменной емкостью 0,9 мг-экв/г в алюминиевой форме и анионит марки АН-31 с обменной емкостью 2,2 мг-экв/г при разном соотношении обменных емкостей катионита и анионита. Перемешивают воду в течение 2 мин и отстаивают , В очищенной воде определ ют цветность и мутность стандартным фотоколориметрическим методом с реактивом - сульфосалициловой кислотой, содержание остаточного алюмини  стандартным фотоколориметрическим методом с реактивом - стильбазо, а также величину рН. Результаты опытов представлены в таблице.RR 00 00 1 The invention relates to methods for treating natural and waste waters and can be used in water treatment processes and for treating waste water in the kinic, petrochemical and other industries, the purpose of the invention is to increase the degree of purification of natural and waste waters. Examples 1-5. In a beaker pour 1 liter of water, having the following EE quality indicators: chromaticity 182 degrees. PCS; turbidity of 6.8 mg / l; iron content about 211 mg / l; salinity 108 mg / l; pH 7.3. A mixture of solid phase cation exchanger KU-2-8 with an exchange capacity of 0.9 mEq / g in aluminum form and an anion exchanger of the brand AN-31 with an exchange capacity of 2.2 meq / g at a different ratio are added to the water. exchange capacity of cation exchanger and anion exchange resin. Water is stirred for 2 minutes and settled. In purified water, the color and turbidity are determined by the standard photocolorimetric method with a sulfosalicylic acid reagent, the residual aluminum content by the standard photocolorimetric method with a stilbazo reagent, and the pH value. The results of the experiments are presented in the table.
