Description

A kind of water purification water storage device
Technical field
The invention belongs to water storage facility technical fields, and in particular to a kind of water purification water storage device.
Background technology
At present, global water resource is increasingly deficient, and water shortage phenomenon is extremely prominent all over the world, the drinking water of people and life All there are shortage problems for industrial water.But at the same time, Storm Flood Disasters are more and more frequent, and a large amount of increasings of urban ground hardening Add, Storm Sewer Network impeded drainage, it is serious to easily cause city ponding, generates waterlogging disaster.It is stored up for this purpose, can be set at present in subsurface Pond or collecting pit, to collect rainwater, such as Chinese patent literature CN 203741704U disclose a kind of for viaduct Rainwater collection system.The system includes initial rainwater pond and pond of regulating and storing, the initial rainwater pond and pond difference of regulating and storing It is connected with inlet channel, further includes silica sand purification cistern, the silica sand purification cistern is arranged on the top in pond of regulating and storing, leads to Immersible pump is crossed to connect with pond of regulating and storing.
In above-mentioned technology, not only can a large amount of rainwater be collected, while can also lead to pond is regulated and stored by initial rainwater pond It crosses silica sand purification cistern and carrys out purifying water body.But above-mentioned technology in silica sand purification cistern because setting silica sand well room, and it is wrapped Including the cavity structure of multiple interconnections, the wall between the cavity structure of multiple interconnections is built up by silica sand building block, This is greatly lowered the water-holding capacity of silica sand purification cistern, while also leads to be deposited on silt and the dirt of silica sand well room bottom of pond Mud etc. cannot be discharged effectively.
Invention content
For this purpose, to be solved by this invention, to be existing water purification water storage device lack there are storage capacity difference and spoil disposal are difficult It falls into, and then a kind of live storage volume of offer is big, the easy water purification water storage device of spoil disposal.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:
Water purification water storage device provided by the present invention including ontology, including water storage inner cavity, further includes,
Bottom plate close to water storage intracavity bottom setting in the inner, and forms water purification and houses inner cavity between the two;
Several drainage units, are arranged at intervals at intracavitary in the water storage, have what is extended towards the water storage inner cavity top Drainage cavity, the inner cavity of the drainage cavity house inner cavity with the water purification and connect, and water inlet flow is formed between adjacent drainage unit Runner.
Further, the bottom plate is inclined relative to horizontal setting, is deposited on increase water inlet flow rate of water flow to wash away Deposit on the bottom plate.
Further, the angle at the inclination angle formed between the bottom plate and horizontal plane is 0.5-5 °.
Further, the height that the water purification houses inner cavity is 0.1-1m.
Further, the length direction of the drainage unit is consistent with water inlet water (flow) direction, and the bottom is deposited on to wash away Deposit on plate
Further, the drainage unit is in a row arranged in intracavitary in the water storage, and between adjacent row and adjacent drainage list The water inlet water stream channel is respectively formed between member.
Further, further include intake tunnel, be set to the side of the ontology, and with the institute more than the bottom plate State the connection of water storage inner cavity;And/or
Water purification collecting tank is set to the water purification and houses interior intracavitary, and the groove top of the water purification collecting tank is not higher than described Water storage intracavity bottom.
Further, further include mud-collecting slot, relatively described intake tunnel is set to the opposite side of the ontology, with collect from The deposit to get off on the bottom plate;And/or
Overflow ducts are connected with the water storage inner cavity and are set on described body sidewall, and its overflow port and the drainage The top of cavity is concordant or the top less than the drainage cavity.
Further, the bottom plate is drainage bottom plate;And/or
The drainage cavity is arranged in a vertical horizontal plane on the bottom plate.
Further, cover board is further included, is covered on the top of the ontology, to close the openend of the water storage inner cavity.
Compared with prior art, the present invention has the advantages that:
(1) close to water storage intracavity bottom bottom plate is being arranged inside, and two in water purification water storage device provided by the present invention Water purification is formed between person and houses inner cavity, while intracavitary is arranged at intervals several drainage units in water storage, which has direction The drainage cavity of water storage inner cavity top extension, inner cavity and the water purification of drainage cavity house inner cavity and connect.By will be between drainage cavity Every setting, the volume accounting of its intracavitary in water storage is reduced, while water purification is set to house inner cavity, substantially increases water storage inner cavity Live storage volume, water storage rate reaches more than 90%, and the prior art, such as silicon in Chinese patent literature CN203741704U The water storage rate of sand purification cistern is not higher than 67%;Furthermore it is water inlet water flow passage between adjacent drainage unit, flow can be facilitated It circulates wherein and washes away the deposit to break off the base on plate, make spoil disposal easy.
(2) water purification water storage device provided by the present invention has water storage and drainage dual function concurrently, simple in structure, at low cost, Using whole dischargeable capacitys of water purification water storage device as carrier is received, flow is unobstructed, with the water that the time of rainfall runoff is short, flow is big Position characteristic is adapted, and can collect more rainwater within the limited time, the water purification that water purification houses interior intracavitary is finally made to reach, very To being higher than《Urban reclaimed water water standard》.By the way that bottom plate is inclined relative to horizontal the length side set and by drainage unit To with water inlet water (flow) direction it is consistent, can further ensure that flow is unimpeded, increase water inlet flow rate of water flow, effectively wash away and be deposited on bottom Deposit on plate facilitates spoil disposal, easy to operate.
(3) water purification water storage device provided by the present invention by the way that bottom plate is arranged to drainage bottom plate, can further increase Filter area reduces drainage unit number, improves the water storage rate of water purification water storage device;By setting water purification collecting tank, when from its In when sending water purification outside, water body filtration is also carried out at the same time, realize water body filtration with the synchronous automatic running of water.
