The incoming waste water mixes with the sludge of anaerobic grains adequately. The utility model can be made in industrial mass production, assembled at the scene and arranged conveniently.
Description
Technical field: the utility model belongs in a kind of environmental protection equipment that is applied in the upflow anaerobic sludge blanket process that high concentrated organic wastewater handles, and the homogeneity that can regulate water distribution automatically is so that the water inlet uniformly distributing of upflow anaerobic sludge blanket process equipment.
Background technology: be the protection environment; reduce environmental pollution; domestic high concentrated organic wastewater is handled the general anaerobic treatment method that adopts makes high concentrated organic wastewater innoxious, and domestic anaerobic treatment equipment has anaerobic digester, anaerobic filter, anaerobism flap sludge sump and upflow anaerobic sludge blanket process.Using more in recent years is upflow anaerobic sludge blanket process, a large amount of anaerobic grain sludges is accumulated at 1-2 rice, bottom of this equipment, mix fully with anaerobic grain sludge immediately behind the high concentrated organic wastewater access arrangement, anerobe degrading organic contaminant in wastewater in the anaerobic grain sludge, has residence time weak point, the processing efficiency height, the operational management characteristic of simple.But evenly whether the water distribution of the processing efficiency of upflow anaerobic sludge blanket process height and this equipment, whether mixed relationship is great fully with anaerobic grain sludge for high concentrated organic wastewater, and the water dispensing apparatus of upflow anaerobic sludge blanket process is the problem studied of experts and scholars both at home and abroad at present.In the prior art, the water dispensing apparatus of upflow anaerobic sludge blanket process has two classes at home.The first kind is a multipoint water feeding, this water dispensing apparatus adopts 4-8 place, the bottom water inlet of upflow anaerobic sludge blanket process, striving making into, water and anaerobic grain sludge mix, the water inlet uphill process in the anaerobic grain sludge thorough mixing, but still there is the dead band of water inlet in the water distribution of device, between water entry and the water entry, water entry around have the water inlet dead band, the mixed effect of water inlet and anaerobic grain sludge is bad.Second class is a pulse water-feeding, this water dispensing apparatus adopts 1-2 place, the bottom water inlet of upflow anaerobic sludge blanket process, water inlet adopts the mode of intermittent pulse to intake, flow velocity is bigger during pulse water-feeding, the water inlet and the anaerobic grain sludge of big flow mix, flow velocity is zero when feeding and intermittent, anaerobic grain sludge precipitates again, and the water distribution of this device exists still water inlet to be easy to generate to penetrate that the mixed effect of anaerobic grain sludge district and short stream, water inlet and anaerobic grain sludge is bad, anaerobic grain sludge is easy to generate sedimentary phenomenon.The construction of the upflow anaerobic sludge blanket process equipment of China's high concentrated organic wastewater processing at present is increasing, the water dispensing apparatus paid more and more attention of upflow anaerobic sludge blanket process, and the water inlet distributed uniform, the good mixing effect of water inlet and anaerobic grain sludge, can not produce the phenomenon that penetrates anaerobic grain sludge and short stream, the speed change eddy flow water dispensing apparatus of the upflow anaerobic sludge blanket process that cost is low, reliable yet there are no report.
Summary of the invention: anaerobic grain sludge and short stream, mixed effect are bad, anaerobic grain sludge is easy to generate sedimentary phenomenon for the water dispensing apparatus that overcomes upflow anaerobic sludge blanket process in the prior art exists the dead band of water inlet, water inlet to be easy to generate to penetrate.Goal of the invention of the present utility model is a kind of even water distribution of design, and the good mixing effect of water inlet and anaerobic grain sludge can not produce short stream, reliable speed change eddy flow water dispensing apparatus.This speed change eddy flow water dispensing apparatus is transformed the multipoint water feeding device, the speed change eddy flow water dispensing apparatus of a uniqueness of design, water is into entered along the bottom tangent direction of upflow anaerobic sludge blanket process, water inlet, is risen along the upflow anaerobic sludge blanket process spiral with the anaerobic grain sludge thorough mixing of bottom at upflow anaerobic sludge blanket process bottom eddy flow, has even water distribution, good mixing effect can not produce short stream, reliable characteristics.
The technical scheme that its technical problem that solves the utility model adopts is: the speed change eddy flow water dispensing apparatus of upflow anaerobic sludge blanket process structurally becomes a upper cone form with the bottom design of upflow anaerobic sludge blanket process, waste water is by the speed change eddy flow water dispensing apparatus of a uniqueness, bottom tangent direction along equipment enters, the water inlet distributed uniform.Waste water at first enters water distributing pipe and distributing water room by water inlet pipe and inlet valve, in distributing water room, stop and store, the top of distributing water room is left along the speed change water-distributing gap of the bottom upper cone tangential direction opening of equipment, the opening part of speed change water-distributing gap is equipped with corrosion-resistant offset plate, when flooding velocity is big, corrosion-resistant offset plate magnifies, and making into, the water flow velocity diminishes; When flooding velocity hour, corrosion-resistant offset plate diminishes, and makes into that the water flow velocity increases, and regulates the waste water flow velocity that enters the anaerobic grain sludge district.Waste water by speed change water-distributing gap and corrosion-resistant offset plate along upflow anaerobic sludge blanket process bottom tangent direction enter the anaerobic grain sludge district of bottom, waste water that enters and anaerobic grain sludge thorough mixing, rise along the upflow anaerobic sludge blanket process spiral, avoid the short stream of waste water to penetrate the anaerobic grain sludge district.
The beneficial effects of the utility model are: the speed change eddy flow water dispensing apparatus of upflow anaerobic sludge blanket process structurally becomes a upper cone form that comprises distributing water room, speed change water-distributing gap and corrosion-resistant offset plate with the bottom design of upflow anaerobic sludge blanket process, on function, make waste water pass through the speed change eddy flow water dispensing apparatus of a uniqueness, bottom tangent direction along equipment enters, the water inlet distributed uniform.Speed change eddy flow water dispensing apparatus can be regulated the waste water flow velocity that enters the anaerobic grain sludge district, and waste water enters the anaerobic grain sludge district by speed change water-distributing gap and corrosion-resistant offset plate along the bottom tangent direction of equipment, and the waste water that enters mixes fully with anaerobic grain sludge.The speed change eddy flow water dispensing apparatus of upflow anaerobic sludge blanket process can be produced in batches in batch production, and field assembly is easy for installation.
