Description

II р и м е р 2. Сточную воду сульфат-целnfcino3Horo производства с начальными показател ми: цветность 1170°; ХПК 470 М17л; рН 6,0, обрабатьшают раствором сернокислого алюмини  {доза 86 м1-/л). и отстаивают. Вода после отстаивани , имеет следующие показатели: цветность 112 , ХПК 260 мг/л, мутность 0,48. После отстаивани  воду фильтруют через модифицированный сол ной кислотой керамзит.II p m eme r 2. Sewage sulphate-celnfcino3Horo effluent with initial indicators: chromaticity 1170 °; COD 470 M17l; pH 6.0 is treated with a solution of aluminum sulphate {dose 86 m1- / l). and defend. The water after settling has the following indicators: color 112, COD 260 mg / l, turbidity 0.48. After settling, the water is filtered through hydrochloric acid modified clay.

Характеристика фильтрата и технико-экономические показатели приведены в таблице.Characteristics of the filtrate and technical and economic indicators are given in the table.

Как следует из таблицы, применение.в качестве фильтрующего материала модифицированного сол ной кислотой керамзита обеспечивает увеличение продолжительности защитного действи  загрузки в 2 раза, повышение производительности фильтров на 24-36% и сокращени  расхода промьшкой воды на 53-73%.As follows from the table, the use of a filter material modified with hydrochloric acid claydite provides an increase in the duration of the protective effect of the load by 2 times, an increase in the productivity of filters by 24-36% and a reduction in the consumption of industrial water by 53-73%.
