Изобретение относитс к способам обесфториванн артезнанскнх вод н может быть нспольэовано в хоз йственно-питьевом и производственном водоснабженнн.The invention relates to methods for the destruction of artesans water and can be used in household and industrial water supply.
Известен способ обесфторивани воды, заключающийс в известковании, отстаива Нйн и фильтрации на скорых фильтрах с активным углем (1.iThere is a method of water defluorization, which consists in liming, defending Nyn and filtering on fast filters with active carbon (1.i.
Недостатком этого способа вл етс то, что процесс сложен в технологическом исполнении , длителен, не эффективен в части степени обесфторивани воды и неэкономичен.The disadvantage of this method is that the process is technologically complex, durable, inefficient in terms of the degree of water defluorization and uneconomical.
Известен способ обесфторивани артезианских вод, заключающийс в обработке их сернокислым алюминием во взвешенном слое, осветлении отстаиванием н в последующем фильтровании 2).There is a known method for the defluorization of artesian water, which consists in treating them with aluminum sulphate in a suspended layer, clarifying by settling and subsequent filtering 2).
Указанный способ вл етс наиболее близким по технической сущности и достигаемому эффекту к описываемому изобретению .This method is the closest to the technical essence and the achieved effect to the described invention.
Однако этот способ имеет короткий фильтроцикл (3-6 ч) и малую скорость фильтрации (2-4 м/ч) из-за значительного выноса хлойьев на фильтры. Кроме того, имеет место значительный расход дефи11итного сернокислого алюмини (250-1000 мг/л) и отмечена низка производительность камеры хлопьеобразовани со слоем взвешенного осадка, отстойника-осветлител , где скорость восход щего потока составл ет 0,5-0,7 мм/с, а гидравлическа крупность хлопьев - 0,7- 1,0 мм/сек. При этих услови х процесс обесфторивании малоэффективен.However, this method has a short filter cycle (3-6 h) and a low filtration rate (2-4 m / h) due to the significant removal of the layers on the filters. In addition, there is a significant consumption of deficient aluminum sulphate (250-1000 mg / l) and a low productivity of the flocculation chamber with a layer of suspended sediment, clarifier clarifier, where the speed of the upward flow is 0.5-0.7 mm / s. and the flake size is 0.7-1.0 mm / s. Under these conditions, the process of defluorization is ineffective.
Целью изобретени вл етс интенсификаци процесса путем повышени фильтроцнкла и уменьшени дозы сернокислого алюмини .The aim of the invention is to intensify the process by increasing the filtration tank and reducing the dose of aluminum sulphate.
Поставленна цель достигаетс тем. что обработку сернокислым алюминием ведут в присутствии глинистой суспензии при скорости подачи очищаемого потока 1,22 ,0 мм/сек.The goal is achieved by those. that the treatment with aluminum sulphate is carried out in the presence of a clay suspension at a feed rate of the purified stream of 1.22, 0 mm / s.
При этом концентраци глины в суспензии составл ет 100-200 мг/л, а соотношение сернокислого алюмини к глине --1:1 -1:0,5. Пример 1. Исходную артезианскую воду с концентрацией ионов фтора 8,6 мг/л, рН 8,5 в количестве 0,2 л/сек обрабатываютThe concentration of clay in the suspension is 100-200 mg / l, and the ratio of aluminum sulphate to clay is 1: 1 -1: 0.5. Example 1. The original artesian water with a concentration of fluoride ions of 8.6 mg / l, pH 8.5 in the amount of 0.2 l / s is treated
4/о-ным раствором сернокислого алюмини (1,25 мл/сек) и 2/о-ным раствором глинистой суспензией (2,5 мл/сек).4 / about-ny solution of aluminum sulphate (1.25 ml / sec) and 2 / about-th solution of clay suspension (2.5 ml / sec).
Далее смесь подают в камеру хлопьеобразовани , где поддерживают скоростьNext, the mixture is fed into the flocculation chamber, where it is maintained at
