Abstract
The invention discloses a kind of sewage-treatment plant, including raw sewage storage tank, ceramic membrane filter system and ceramic membrane backwashing system, which is characterized in that it further includes the pretreatment system for sewage being arranged between stoste storage tank and ceramic membranous system.
Description
Technical field
The present invention relates to sewage treatment field more particularly to the sewage-treatment plants of machining sewage.
Technical background
Compared to other industry, machining waste water contains various oils, detergent class substance, has quantum of output big, and color is deep,
The features such as difficult to degrade.Mainly there are the various technologies such as Physical, chemical method and bioanalysis currently for the processing of machining waste water.But
The device and system of these methods are respectively provided with larger limitation, such as take up an area excessive unsuitable investment construction；Treatment effect is bad,
Discharge standard etc. is not achieved.
Ceramic film sewage treatment device in recent years shows preferable treatment effect, and apparatus structure is simple, processing week
Phase is short, water outlet is limpid, is a kind of relatively good sewage-treatment plant.But since machining waste water oil content and solid are suspended
The amount of object is all larger, and the phenomenon that film blocks can be being generated during ceramic film process, device is made to lose filter capacity, in addition,
Simple back washing device can not restore membrane flux completely, and frequently filter efficiency can be greatly reduced in backwash.
Invention content
The present invention proposes a kind of new sewage-treatment plant with ceramic membrane filter system is used, and improved and optimizated, with
In the presence of solving the problems, such as above-mentioned background.
The technical solution adopted in the present invention is：
A kind of sewage-treatment plant, it is special including raw sewage storage tank, ceramic membrane filter system and ceramic membrane backwashing system
Sign is that it further includes the pretreatment system for sewage being arranged between stoste storage tank and ceramic membranous system.
Oils detector and triggering flow diverter are provided in the present invention in raw sewage storage tank, oils detector can be to stoste
Raw sewage oils concentration in storage tank is detected, and sewage separation is introduced pretreatment system for sewage by triggering flow diverter
In.
Pretreatment system for sewage of the present invention is drawn by sewage disinfection treatment slot and circulating slot and the triggering being arranged between
Flow device composition.The raw sewage that oil content does not arrive the setting value of triggering flow diverter is directly entered circulating slot, meets or exceeds tactile
The raw sewage of the setting value of hair flow diverter is then introduced into sewage disinfection treatment slot and is pre-processed, by the Oil in Sewage Water of pretreatment
When class content is less than the setting value for triggering flow diverter, pretreating sewage is introduced into circulating slot.
Equipped with nano bubble device in pretreatment tank of the present invention, nano bubble can be generated, utilizes nano bubble ratio
The big characteristic of surface area pre-processes sewage, reduces oil content.
Backwashing system of the present invention include Rinsing Area and steam cleaner, when the ceramic membrane filter system work one section when
Between occur congestion situations when, manually select unlatching Rinsing Area, it backwashed with clear water, if severe obstruction, manually
Steam cleaner is opened in selection, it is backwashed with steam.
Present invention employs technical solution as above, advantage is as follows：
1) pollution condition for machining waste water can be detected, and shunt processing；
2) stoste is pre-processed using nano bubble method, can preferably improves the quality of stoste, reduce ceramics
The speed that film blocks reduces number of backwashes；
3) apparatus is simple in structure, and ceramic membrane lasts a long time, and good sewage processing effect, the period is short, and treating capacity is big.

Specific embodiment
The present invention is described in further detail below by specific embodiment.
It is a kind of sewage-treatment plant as described in Figure 1.There is oils detector 5 in the stoste storage tank 1, oils concentration can be by
It is read, and stoste is extracted by centrifugal pump in detector reading table.Oils setting value is 50mg/L by the triggering flow diverter 6, when
When oil content is less than 50mg/L, sewage is entered in circulating slot 2-2, the sewage in circulating slot 2-2 is extracted by centrifugal pump, into pottery
Porcelain membrane filtration system 3, sewage are filtered by ceramic membrane filter system 3, and clear water is emitted into Rinsing Area 4-1；When by content
During more than 50mg/L, sewage is introduced into pretreatment tank 2-1, is generated nano bubble by nano bubble device 2-4, is located in advance
Reason sets triggering flow diverter 2-3 values as 50mg/L, when concentration of wastewater is less than triggering flow diverter 2-3 setting values in pretreatment tank 2-1
It is that sewage is entered in circulating slot 2-2, and follow-up process is identical.
When the ceramic membrane filter system 3 work certain time block after, then need to ceramic membrane filter system 3 into
Row backwash, manually opened Rinsing Area 4-1 carry out backwash to ceramic membrane filter system 3；When the ceramic membrane filter system 3 blocks
When serious, steam backwash is carried out to it, manually opened steam cleaner 4-2 carries out anti-ceramic membrane filter system 3 with steam
It washes.
Sewage-treatment plant of the present invention can improve ceramic 3 times of membrane lifetime or more, while good sewage processing effect, period
Short, treating capacity is big.
