The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, specifically, in the present invention,
It since raw water to be processed is typically in former pond or raw water box, is connected to outside, the film portion water inlet end of hyperfiltration membrane assembly immerses
Raw water to be processed causes pressure on the outside of ultrafiltration membrane larger, the water inlet of the water outlet connection negative pressure box of hyperfiltration membrane assembly, negative pressure box
In be negative pressure of vacuum environment, lead to pressure very little on the inside of the ultrafiltration membrane of hyperfiltration membrane assembly, ultrafiltration membrane two sides form pressure difference, and then make
Sewage in raw water box enters negative pressure box by the hyperfiltration membrane assembly, completes filter process, and water pump takes out the water in negative pressure box
Out, restore the vacuum negative pressure condition in negative pressure box, the sewage in raw water box continues filtering into negative pressure box, thus constantly by sewage
Purification reduces energy consumption, so that ultrafiltration membrance filter is easier to be generalized since filter process does not need external force pressurization.
Meanwhile the structure of this kind of hyperfiltration membrane assembly substantially membrane part is intake, water outlet is unified to be discharged, and such structure is dirty
Stain will not enter in hyperfiltration membrane assembly, and cleaning is easier.
Original state, negative pressure box need to pass through vacuum pumping, form negative pressure of vacuum environment.
Further, one-way exhaust valve is opened up at the top of negative pressure box, facilitates to form subnormal ambient, it when specific operation, will
Water is filled in negative pressure box, air is discharged by the one-way exhaust valve that top opens up, then detaches water to form negative pressure using water pump,
It starts to work.
Further, raw water box is set, and raw water box open can be arranged, and can also add case lid, be arranged on case lid ventilative
Hole, its object is to keep the atmospheric pressure in raw water box consistent with the external world.In the environment of needing to save using space, negative pressure box
Can be set in raw water box, or raw water box and negative pressure box are close to setting, or even be set as the structure of one case two Room, it is intermediate every
Through-hole is set on plate and is connected to two Room.It will be usually attached between raw water box and negative pressure box using pipeline.
Further, water pump is located in negative pressure box, and structure integrated level is higher, the water outlet of the water outlet connection negative pressure box of water pump
Mouthful, more compact structure, but need to be arranged water pump access hole, sealing device is installed at access hole, both ensure that normal service,
It ensure that the negative regulation in negative pressure box.Water pump also can be set outside negative pressure box, the water outlet of the water inlet and negative pressure box of water pump
Mouth connection, structure is simpler, and installation and maintenance are more convenient.
Further, negative pressure box water outlet road connects reclaimed wastewater reuse equipment, and the feed-water valve of reclaimed wastewater reuse equipment
With the switch gearing of water pump, when guaranteeing that feed-water valve is closed, water pump stalling avoids booster.
Further, sewage draining exit is arranged in raw water box bottom, cleans for raw water box, meanwhile, outer water tube is set, and connection is super
The water outlet of filter membrane component, by supply equipment, such as running water pipe or pump pressurizing unit supply water outer water tube, to hyperfiltration membrane assembly into
Row back flush, the sewage after flushing are discharged from sewage draining exit.The control valve installed in outer water tube is one-way water inlet valve, can only
Water inlet, avoids interference during drainage to pressure in negative pressure box, guarantees the closure of negative pressure box.
It has the advantages that design science, filter process Non-energy-consumption, structure are simple, easy to clean.
