Description
Technical field
The present invention relates to a kind of Treated sewage reusing treatment technology, be specifically related to a kind of sanitary sewage is processed after again
The system and device utilized.
Background technology
The shortage of water resource becomes focus of concern already.According to statistics, 617 cities of China have 400
Multiple cities are hydropenia city, and more than 50 city has been enter into hydropenia crisis state, and water shortage status goes from bad to worse.
Especially as the quickening of urban construction speed, improving constantly of quality of residents'life, high-rise residential building instead of former
The ranch house come, family, in addition to daily food and drink and slurry, with the addition of again bathing, flushes the toilet, cleans
The high water usage projects such as vehicle.
At present China residential quarter is equipped with the few of Treated sewage reusing measure, and in residential households domestic water about
The regenerated water source of 40-50% is wasted because of invalid use.Resident few in number collects rinsing clothes in washer
Draining after draining afterwards and shower, for toilet flushing, or cleans floor, cleans dirt etc..This
Although water resource has been saved in a little behaves to a certain extent, but these waste water storages are the most difficult, and water quickly goes bad,
The smell is awful.If this part of contaminated water being collected, reliable process is used to be acted upon, it is possible to save a large amount of
Water resource.But current small-sized Treated sewage reusing device, is not appropriate for promoting the use of in the family, and reason is:
(1) waste water collected is not processed by device, as Chinese patent 200510020034.8 discloses a kind of family
In front yard, water collects feedway automatically, and this device does not have removal ability to water pollutant, and the middle water of collection is easy
Breed bacteria etc. are cured the disease microorganism, unsuitable popularization and application；(2) based on filtering technique, there is filtration and be situated between
The problems such as matter is complicated, backwash process difficulty, as Chinese patent CN200910027933.9 discloses a kind of domestic
The method that Treated sewage reusing processes, is characterized in that using oil-repellent filter component and activated carbon filtering technique, but exists
Backwash difficulty and regeneration issues, apply in the family do not have long-lasting；(3) technique is used easily to bring two
Secondary pollution, as Chinese patent CN201110219715.2 discloses a kind of recycled water in family processing method and recycling
Device, this device have employed traditional aeration and flocculation sediment technique, on the one hand sewage is cured the disease microorganism due to
Aeration may dissipate in air；On the other hand flocculation dosing complex operation, medicament used easily causes secondary
Pollute, be not appropriate for family and use.
To this end, how according to the economic level of resident, a kind of low cost of exploitation, highly reliable, versatility good,
It is easy to safeguard, be easy to the small household sewerage disposing device of popularization, becomes current problem demanding prompt solution, and
There is bigger social benefit.The present invention proposes a kind of novel Domestic reclaimed water treatment equipment, in conjunction with life dirt
Water feature and applied environment, it is proposed that intensified by ultrasonic wave electricity flocculates, in conjunction with the integrated apparatus of membrane separation technique,
To with relatively low cost, obtaining satisfied water-saving result.

Film water outlet suction in filter membrane component and backwash time.In suction stage, hyperfiltration membrane assembly persistently produces water；Instead
Wash the stage, go out water pump using the water in filtered water tank as backwashing water, it is achieved hyperfiltration membrane assembly membrane flux recovers.
Domestic reclaimed water treatment equipment has coupled electric flocculation, ultrasound wave and membrane separation technique, and coupling technique has collaborative
Effect, is embodied in: under applying direct current electric field effect, and cathode-anode plate occurs electrode reaction respectively, to dirt
The removal of dye thing includes flocculation, the most floating and oxidation-reduction process, thus purifies sewage；The sky that ultrasound wave produces
Cave effect, is conducive to strengthening electricity flocculation process, it is ensured that mixed liquor is in suspended state, and the shearing force of generation is favourable
In decelerating membrane pollution, maintain stablizing of membrane flux.
The beneficial effects of the present invention is, (1), according to domestic water feature, uses electricity coagulation process to instead of biography
The coagulation dosing technology of system, eliminates the trouble of dosing so that this technology water treatment applications in the family is the most just
Victory；(2) application ultrasonic technology, on the one hand can strengthen electricity coagulation process, improve pollutant removal,
On the other hand instead of aeration agitation technology so that apparatus of the present invention use safer in family, reduce secondary
Pollute；(3) ultrafiltration membrance filter can be greatly improved effluent quality, uses the time relay to control backwash process peace
Complete reliable, it is simple to domestic. applications.
