На фиг.1 представлено устройство предварительной очистки сточных и ливневых вод.Figure 1 presents the device for pre-treatment of wastewater and storm water.
Устройство содержит емкость 1 с впускным патрубком 2, через который в неё поступают сточные и ливневые воды. Емкость 1 разделена на отсе- ки. Первый отсек 3, в который непосредственно первоначально поступают воды, выполнен в виде ковша 4, являющимся фактически накопительным лотком, при этом одна из стенок 5 ковша установлена вертикально, снабжена роликами 6, посредством которых ковш перемещается вверх, вниз по направляющим 7, закрепленным на стенке 8 емкости. Вторая стенка 9 ковша 4 расположена наклонно, а дно 10 выполнено перфорированным, а свободный торец 11 второй стенки 9 снабжен козырьком 12, загнутым во внутрь отсека 3. Ниже перфорированного дна 10 установлен линейный аэратор 32. На стенке 8 емкости 1 ниже направляющих 7 закреплен ограничитель 13, на который опирается своим дном 10 ковш 4. Впускной патрубок 2 расположен над отсеком 3. Второй отсек 14 образован перфорированным дном 10 ковша 4 и наклонно расположенной стенкой 9 ковша 4 и наклонно установленной задерживающей решеткой 15, причем решетка установлена параллельно наклонной стенке 9 ковша 4. Решетка 15 образовано набором пластин 16 установленных с прозором, причем величина прозоров между пластинами 16 меньше перфорации, выполненной в дне 10 ковша 4. Решетка 15 нижним концом 17 шарнирно закреплена в посадочном гнезде 18 на дне 19 емкости 1, а свободный консольный конец 20 снабжен вертикальной перегородкой 21 и пластиной 33. Нижняя часть решетки 15 закрыта панелью 22, так что её верхняя грань 23 расположена в одной вертикальной плоскости A-A с образующей нижнего 24 аэратора. Пластины 16 каскадно пронизаны линейными аэраторами 25, торцы которых закрыты заглушками, а каждый из аэраторов 24, 25 взаимодействует с распределителем 26 воздуха. Третий отсек 27 образован задерживающей решеткой 15 и второй стенкой 28 емкости 1, в которой выполнено переливное отверстие 29 для перелива предварительно очищенной воды в последующие очистные емкости. Устройство снабжено компрессором 30, блоком управления 31.The device contains a container 1 with an inlet pipe 2, through which sewage and storm water enter it. Capacity 1 is divided into ki. The first compartment 3, which directly receives water directly, is made in the form of a bucket 4, which is actually a storage tray, while one of the walls 5 of the bucket is mounted vertically, equipped with rollers 6, by means of which the bucket moves up and down along the guides 7 mounted on the wall 8 containers. The second wall 9 of the bucket 4 is inclined, and the bottom 10 is perforated, and the free end 11 of the second wall 9 is equipped with a visor 12, bent into the compartment 3. Below the perforated bottom 10 there is a linear aerator 32. A limiter is mounted on the wall 8 of the tank 1 below the guides 7 13, on which the bucket 4 rests with its bottom 10. The inlet pipe 2 is located above the compartment 3. The second compartment 14 is formed by the perforated bottom 10 of the bucket 4 and the inclined wall 9 of the bucket 4 and the oblique mounted delay grille 15, and the grille is installed Lena parallel to the inclined wall 9 of the bucket 4. The lattice 15 is formed by a set of plates 16 installed with a gap, and the gap between the plates 16 is less than the perforation made in the bottom 10 of the bucket 4. The lattice 15 with its lower end 17 is pivotally mounted in the seat 18 on the bottom 19 of the tank 1 and the free cantilever end 20 is provided with a vertical partition 21 and a plate 33. The lower part of the grill 15 is covered by a panel 22, so that its upper face 23 is located in the same vertical plane AA with the generatrix of the lower 24 aerator. The plates 16 are cascaded with linear aerators 25, the ends of which are closed by plugs, and each of the aerators 24, 25 interacts with the air distributor 26. The third compartment 27 is formed by a delaying grid 15 and a second wall 28 of the tank 1, in which an overflow hole 29 is made for overflowing pre-treated water into subsequent treatment tanks. The device is equipped with a compressor 30, a control unit 31.
Устройство работает следующим образом. Сточные и ливневые воды через впускной патрубок 2 поступают в первый отсек 3, в котором задерживаются крупные механические включения, а вода проходит сквозь перфори- рованное дно 10 в отсек 14. При установке данного устройства в системах биологической очистки в первый отсек может быть подан регенерационный активный ил, при этом уже в первом отсеке будет происходить аэробная биологическая очистка, что исключает появление дурного запаха и способствует био деградации мусора органического происхождения уже на стадии предварительной очистки сточных вод. Во втором отсеке 14 вода также фильтруется и мусор задерживается на решетке 15, а так как решетка установлена наклонно то мусор осаждается к её основанию. Кроме того, для эффективной очистки перфорированного дна 10 и решетки 15 периодически, или постоянно, в зависимости от загрязнений сточных, а особенно ливневых вод, подается воздух в линейные аэраторы 32, 24, 25, , которые установлены каскадно, в связи с чем решетка 15 аэрируется, т.е. продувается воздухом и механические включения поднимаются воздухом вверх. Благодаря наличие панели 22 и пластины 33 исключаются мертвые зоны в отсеке 14, не продуваемые воздухом. При подаче воздуха в линейные аэраторы происходит барботаж воды во втором отсеке 14, вызывая подъем уровня воды в отсеке выше козырька 12, тем самым создаются условия для перетекания самотеком воды с мусором в отсек 3, где весь мусор собирается в ковше 4. Благодаря шарнирному закреплению задерживающей решетки 15, можно менять её угол наклона, тем самым меняя площадь зеркала воды в отсеке 14, что создает условия для лучшего перетекания воды с мусором при подаче воздуха в линейные аэраторы. По мере накопления мусора в ковше, его поднимают и мусор выбрасывают, при этом не страшно что какой то мусор в момент отсутствия ковша попадет во второй отсек, после установки ковша, при аэрации решетки мусор вместе с водой перетечет в ковш.The device operates as follows. Wastewater and storm water through the inlet pipe 2 enter the first compartment 3, in which large mechanical inclusions are retained, and the water passes through the perforated bottom 10 in compartment 14. When this device is installed in biological treatment systems, regenerative activated sludge can be fed into the first compartment, and aerobic biological treatment will occur in the first compartment, which eliminates the smell of fumes and promotes biodegradation of organic waste already at the stage of pre-treatment of wastewater. In the second compartment 14, the water is also filtered and the debris lingers on the grate 15, and since the grate is installed obliquely, the garbage settles to its base. In addition, for effective cleaning of the perforated bottom 10 and the grill 15 periodically, or constantly, depending on the pollution of sewage, and especially storm water, air is supplied to the linear aerators 32, 24, 25, which are installed in cascade, in connection with which the grill 15 aerated, i.e. blown by air and mechanical impurities rise air up. Due to the presence of the panel 22 and the plate 33, dead zones in the compartment 14, which are not blown by air, are eliminated. When air is supplied to the linear aerators, water sparges in the second compartment 14, causing the water level in the compartment to rise above the canopy 12, thereby creating the conditions for gravity to flow water with garbage into compartment 3, where all garbage is collected in the bucket 4. Thanks to the hinged fastening of the delay lattice 15, it is possible to change its angle of inclination, thereby changing the area of the water mirror in compartment 14, which creates the conditions for better flow of water with debris when air is supplied to linear aerators. As the garbage accumulates in the bucket, it is lifted and the garbage is thrown away, and it is not scary that some garbage will fall into the second compartment when the bucket is missing, after installing the bucket, when the grate is aerated, the garbage and water will flow into the bucket.
