State the water outlet of raw water box.
The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, specifically, in the present invention,
Unified water inlet is arranged in hyperfiltration membrane assembly, and waste water is purified from inside to outside by ultrafiltration membrane, since raw water to be processed is typically in
It in former pond or raw water box, is connected to outside, both ultrafiltration membrane inside pressure is larger for the water inlet end of hyperfiltration membrane assembly, hyperfiltration membrane assembly
Film portion water outlet sealing connection negative pressure box water inlet, be negative pressure of vacuum environment in negative pressure box, lead to the super of hyperfiltration membrane assembly
Pressure very little on the outside of filter membrane, ultrafiltration membrane two sides form pressure difference, and then it is negative to enter raw water to be processed by the hyperfiltration membrane assembly
Case is pressed, filter process is completed, water pump extracts the water in negative pressure box out, restores the vacuum negative pressure condition in negative pressure box, and raw water continues
Filtering is into negative pressure box, so that sewage purification is constantly reduced into energy consumption since filter process does not need external force pressurization,
So that ultrafiltration membrance filter is easier to be generalized.
Meanwhile the structure of this kind of hyperfiltration membrane assembly makes water inlet unified, pressure is more prone to produce, and hyperfiltration membrane assembly can be with
Far from raw water to be processed, external devices is avoided to be corroded, due to the installation of separate type, maintenance is also more convenient.
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, film portion water outlet is set in negative pressure box, and the water purification of exudation is directly accumulated in negative pressure box, space utilization
Rate is higher, and volume is smaller.
Further, water pump is mounted in negative pressure box, is opened up water pump access hole, is further reduced volume, and it is integrated to enhance it
Degree, water pump can also be external, convenient to overhaul.
Further, water pump water outlet connect reclaimed wastewater reuse equipment, and the feed-water valve of reclaimed wastewater reuse equipment and
The switch gearing of water pump, when guaranteeing that feed-water valve is closed, water pump stalling avoids booster.
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.
It has the advantages that design science, filter process Non-energy-consumption, structure are simple, convenient to overhaul.
