(54) ОТСТОЙНИК(54) DRAWER

II

Изобретение относитс к устройствам дл очистки сточных вод, в частности навозных стоков, методом гравитационного осаждени .This invention relates to wastewater treatment plants, in particular manure, by gravity sedimentation.

Известен отстойник, включающий корпус с установленными в нем пластинами, устройство дл распределени стоков, устройство дл сбора осветленной жидкости и устройство дл сбора осадка.ЧA settling tank is known, comprising a housing with plates installed therein, a device for distributing effluents, a device for collecting clarified liquid, and a device for collecting sludge.

Работа его эффективна (при высоте чеек между пластинами 20-80 мм) при концентрат ции взвешенных веществ в исходных стоках не более 1 г/л 1J.Its operation is effective (with a height of cells between the plates of 20–80 mm) with a concentration of suspended solids in the initial effluent of not more than 1 g / l 1J.

Концентраци загр знений в навозиых стоках 10-20 г/л, поэтому при работе известных тон-, кослойных отстойников происходит забива Ше межпластинного пространства пакетов. Во избежание забивани межпластинное рассто ние увеличивают до 150-200 мм, что снижает эффективность работы отстойника при заданных габаритных размерах и производительности.The concentration of contaminants in the manure is 10–20 g / l, therefore, during the operation of well-known ton- and layer-lagal settlers, the Shee inter-plate space of the packages is clogged. In order to avoid clogging, the inter-plate spacing is increased to 150–200 mm, which reduces the efficiency of the settling tank for given dimensions and performance.

Целью изобретени вл етс повышение эффективности использовани отстойника путем разделени потоков очищаемой жидкости т пластинах и предотвращени их забивани .The aim of the invention is to increase the efficiency of the use of the settler by separating the streams of the liquid to be cleaned from the plates and preventing their clogging.

Поставленна цель дЬстигаетс тем, что отстойник , содержащий корпус с пластинами, узлы ввода и распределени исходной жидкости и вывода разделенных фаз, снабжен установленными между пластинами и параллельно им пе: регородками, при этом их входньге кромки смещены по горизонтали относительно друг друга-и входных кромок пластин.The goal is achieved by the fact that the settling tank, comprising a housing with plates, input and distribution units for the initial fluid and output for the separated phases, is provided with partitioned between the plates and parallel to them: the partition walls, while their entrance edges are horizontally offset relative to each other and the input edges plates.

На фиг. 1 представлен предложенный отCToiouoc , продольный разрез; на фиг. 2 10 сечение А-А на фиг. 1.FIG. 1 shows a longitudinal section proposed by CToiouoc; in fig. 2 10 section A-A in FIG. one.

Отстойник содержит корпус 1, узлы ввода и распределени исходной жидкости 2, выво- да разделенных, фаз - осветленной жидкости 3 и осадка 4. Узел ввода и распределени ис15 ходной жидкости 2 включает вертикальную перегородку 5 и струенаправл ющие лопатки 6. Внутри корпуса 1 отстойника установлены пластины 7, межру которыми размещены дополнительные пластины 8. Дополнителы1ые плас20 тины 8 закреплены в корпусе 1 отстойника со смещением по длине относительно входньи( кромок пластин 7.The sump contains a housing 1, input units and distribution of the source liquid 2, output separated phases - clarified liquid 3 and sediment 4. The input unit and distribution of the source liquid 2 includes a vertical partition 5 and guide vanes 6. Inside the sump housing 1 plates 7, between which additional plates 8 are placed. Complementary plates 8 are fixed in the tank 1 with a displacement along the length relative to the entrance (edges of the plates 7.

Claims

The sump works as follows. 39 The initial fluid (manure drains) is supplied to the inlet and distribution unit 2, is evenly distributed first along the ishrin (vertical partition 5), then along the height (directing vanes 6). The wastewater distributed by the volume of the settling tank enters the space between the plates 7 where the initial precipitation of larger impurities occurs, while the concentration of the effluent decreases. Then, the drains, partially separated, enter the space between the plates 7 and the additional plates 8, where along the way of their movement an additional separation occurs and the concentration of suspended matter decreases. The isolated solid fraction slides down the plates down to the outlet 4 of the sediment and is removed from the sump. The clarified liquid flows to the outlet of the clarified liquid 3 and is also removed from the sump. This invention allows, by gradually decreasing the inter-plate spacing, an increase in the surface area of 1) planting, which demonstrates the efficiency of sewage separation for a given productivity and overall dimensions of the settler. Claims The sump, comprising a housing with plates, input units and distribution of the source fluid and output of separated phases, characterized in that, in order to increase the efficiency of the use of the sump by separating the streams of the liquid being cleaned on the plates and preventing them from clogging, it is provided with between the plates and in parallel them partitions, while their input edges are shifted horizontally relative to each other and the input edges of the plates.
