Abstract
Изобретение относитс к способам очистки природных вод, может использоватьс в подготовке водоочистки, позвол ет сократить расход сернокислого алюмини . Речную воду в количестве 78-84об.% с содержанием взвешенных веществ 1800 мг/л при перемешивании обрабатывают сульфатом алюмини дозой 32 мг/л, отстаивают и отдел ют осадок. В воду, отделенную от осадка, при перемешивании ввод т оставшиес 16-22% исходной речной воды от общего количества очищаемой воды, а затем обрабатывают сернокислым алюминием, дозой 45 мг/л,и полиакриламидом дозой 2,5 мг/л, отстаивают и отдел ют осадок. Дл сравнени на второй стадии очистки не используют добавку исходной воды, в остальном провод т процесс очистки аналогично описанному выше. В результате при одинаковой степени очистки при введении на вторую стадию 16-22% исходной речной воды от общего количества очищаемой воды происходит снижение расхода сернокислого алюмини с 77 до 70-071,9 г/м3. 1 табл.The invention relates to methods for purifying natural waters, can be used in the preparation of water purification, and reduces the consumption of aluminum sulphate. 78-84 vol.% River water with a suspended matter content of 1800 mg / l with stirring is treated with aluminum sulfate at a dose of 32 mg / l, settled and the precipitate is separated. With stirring, the remaining 16-22% of the original river water from the total amount of purified water is introduced into the water separated from the sediment, and then treated with aluminum sulphate, 45 mg / l, and polyacrylamide with 2.5 mg / l, defend and are precipitate. For comparison, in the second purification stage, no addition of the source water is used, otherwise the purification process is carried out as described above. As a result, with the same degree of purification, with the introduction of 16–22% of the original river water to the second stage, the consumption of aluminum sulphate from 77 to 70–071.9 g / m 3 decreases from the total amount of water to be purified. 1 tab.
Description
нием взвешенных веществ 1800 мг/л внос т 32 мг сульфата алюмини , перемешивают 3 мин, а затем 30 мин отстаивают и отдел ют образовавшийс осадок. В воду, отделенную от осадка, ввод т 45 мг сульфата алюмини , перемешивают 3 мин, ввод т 0,5 мг поли- акриламида и после трехминутного перемешивани отстаивают 3U мин, отдел ют образовавшийс осадок. В осветленной воде определ ют содержание взвешенных веществ.by weighing 1800 mg / l of suspended solids, 32 mg of aluminum sulfate are added, stirred for 3 minutes, and then settled for 30 minutes and the precipitate formed is separated. 45 mg of aluminum sulphate is introduced into the water separated from the precipitate, stirred for 3 minutes, 0.5 mg of polyacrylamide is added and, after three minutes of stirring, 3U minutes are settled, the precipitate is separated. In clarified water, the content of suspended substances is determined.
Результаты опытов представлены в таблице.The results of the experiments are presented in the table.
Из представленных в таблице данных следует, что введение на вторую стадию дополнительно к воде, прошедшей первую стадию очистки, 16-22% исходной речной воды приводит к снижению расхода сульфата алюмини с 77 доFrom the data presented in the table, it follows that the introduction of the second stage, in addition to the water that has passed the first stage of purification, 16-22% of the original river water leads to a decrease in the consumption of aluminum sulfate from 77 to
