Abstract
The utility model discloses a filter pond with variable flow rates, and relates to a water purification and filtering treatment device, in particular to a filter pond. The filter pond with variable flow rates includes a circular pond body with two variable diameters, a ring of water collection tank is arranged at the top of the pond body, a filtered water and drain outlet is formed in the bottom of the water collection tank, a discharge opening is formed in the lower part of the side edge of the pond body, a filtered water outlet and backwashing water inlet is arranged at the bottom of the pond body, fine silica sand filter materials are arranged in the center of an inner cavity of the pond body, medium silica sands are arranged below the fine silica sand filter materials, coarse silica sands are arranged below the medium silica sand filter materials, pebbles are arranged at the lower part of the coarse silica sands, a filter plate is arranged below the pebbles, strainers are arranged on the filter plate, and a mushroom type water distributor is arranged at the bottom of the inner cavity of the pond body. The filter pond with variable flow rates fully utilizes the theory that layered distribution can be achieved after the silica sand backwashing, so that the filter rate can be constantly changed; the filter pond with variable flow rates has the characteristics of high filter rate and filter precision, long service life of the filter materials, and the like.
Description
Technical field
The utility model discloses unsteady flow speed type filtering ponds, relate to a kind of purification filtering water treatment facilities, be specially filtering ponds.
Background technology
Quartz sand filter tank is widely used, especially industrial water supply, domestic water and middle water Recycling Project, but ubiquity filtering accuracy not high, consume energy high, the shortcoming such as filtering velocity is low, and effluent quality is unstable.
Utility model content
The technical problems to be solved in the utility model is to provide unsteady flow speed type filtering ponds, solve existing quartz sand filter tank filtering accuracy not high, consume energy high, the problems such as filtering velocity is low, for addressing the above problem, the utility model adopts following technical scheme: unsteady flow speed type filtering ponds, comprise the circular pond body that is provided with twice reducing, body top, described pond is provided with a circle water leg, and described water leg bottom is provided with filters water outlet and sewage draining exit; Bottom, limit, side, described pond is provided with discharging opening; Body bottom, described pond is provided with filters water outlet and recoil water inlet; Intracoelomic cavity middle part, described pond is provided with fine quartz sand filtrate, under described fine quartz sand filtrate, be provided with middle quartz sand, under described middle quartz sand filter media, be provided with thick quartz sand, described thick quartz sand bottom is provided with cobblestone, under described cobblestone, be provided with filter plate, on described filter plate, be provided with water cap, intracoelomic cavity bottom in described pond is provided with mushroom-shaped water-locator.
Described water leg is zigzag water leg.
Described fine quartz sand particle diameter 0.45～0.65mm, loading is highly 250～650mm.
Described middle quartz sand particle diameter 0.65～0.85mm, loading is highly 300～700mm.
Described thick quartz sand particle diameter 0.85～1.2mm, loading is highly 200～600mm.
