Description
Technical field
The present invention relates to food and drink waste water process field, a kind of specifically micro-nano food and drink waste water pretreating process.
Background technology
Main component is leftover and water in food and drink waste water, organic with starch, food fiber class, animal tallow class etc.
Thing is main component, has the characteristics that nutritional ingredient is high, moisture content is high, grease and salt content are high, perishable fermentation is smelly, if will
Collect, transport and dispose together with house refuse, it will seriously affect city appearance environment and resident living, can also influence life rubbish
The final disposal effect of rubbish；If it is immediately discharged to municipal wastewater pipeline, the source of " gutter oil " will be become, cause pipe network to block up
Plug, influences follow-up sewage treatment process, produces corrosion and peculiar smell, causes public sewage disposal failure.In addition, contain in kitchen garbage
There is substantial amounts of organic matter, its nutrition was not only comprehensive but also abundant, as long as passing through suitable treatment technology, so that it may so that food and drink waste water obtains
Sufficiently " recycling " utilizes.
Therefore, food and drink waste water, which has to pass through, anticipates, and effluent quality index is up to state standards after defined limit value, side
It can arrange to urban drainage pipe network, Storm Sewer Network must not be discharged into or directly arranged to natural environments such as urban rives.
Food and drink waste water is directed at this stage, it is former using grease density contrast supplemented by air supporting class method mainly based on physical method
Reason, naturally quiet heavy stop are layered, and top oil slick slag is automatically drained out by machinery, electrically operated valve mode, or by manually pulling out, and
Air supporting class device copies as sets, and bubble diameter is big, only plays the effect of oxygenation water body flow, there are separating effect for such method
The effect of difference, the defects of water quality is not up to standard, the residence time is short, operation and maintenance are poor, high failure rate, water-oil separating, loses, and pre-processes
Effect it is poor.
The content of the invention
The purpose of the present invention is to solve inferior separating effect of the prior art, water quality is not up to standard, the residence time is short, fortune
Row safeguards the defects of poor, high failure rate, there is provided a kind of micro-nano food and drink waste water pretreating process solves the above problems.
To achieve these goals, technical scheme is as follows：The invention discloses a kind of micro-nano food and drink waste water
Pretreating process, comprises the following steps that：
(1), kitchen food and drink waste water collects rear flow by gravity and is discharged into debris isolated area, separates except the bulky grain in waste water is miscellaneous
Thing, then bulky grain debris is sent to house refuse and is collected a little, the centralized processing of transport of refuse station；
(2), the tiny particles content in waste water is sunk naturally along 30 ° of cone buckets, is stored up by residue is drained into outside pull of vacuum
Tank；
(3), after the large granular impurity and little particle impurity in removing food and drink waste water, food and drink waste water is saturating by the circular hole of 6mm
Cross, when flowing through water-oil separating area front end, the ozone that ozone generator is sent is delivered to micro-nano bubble generator, in micro-nano gas
Under the action of steeping generator, food and drink waste water is sufficiently mixed rear cycle with ozone and shears, before multi-angle jet stream to water-oil separating area
End, produces micro-nano bubble, micro-nano bubble remains in water-oil separating area in a manner of bubble at this time；
(4), the micro-nano bubble distribution in waste water adsorbs suspended matter in water body, and aggregation is agglomerating to float up to water surface
Scum silica frost is formed, is removed by scum silica frost from arranging device automatic scraping to oil slick inder pot and collects recycling；
(5), waste water flows to reaction Jing Chen areas from water-oil separating area end, after standing 2-3min, sets and samples in water outlet
Valve, using sampling valve unit monitoring water quality, is discharged after water quality reaching standard.
Preferably, in the step (1), the bulky grain debris is more than the debris of 6mm for particle diameter.
Preferably, in the step (2), the little particle debris is less than the debris of 6mm for particle diameter.
Preferably, in the step (2), after the little particle debris in residue storage tank is blended drying, addition biology
Preparation, is prepared organic compost after stirring evenly.
Preferably, in the step (3), a diameter of 5-30 μm of the micro-nano bubble.
Preferably, in the step (4), the suspended matter includes suspended oil, bottom fine particle deposit.
The present invention has the following advantages compared with prior art：
For instantaneous delivery is big, water-quality constituents is complicated, debris is more, animal and plant fat content is high, organic pollution concentration
High food and drink waste water pretreatment, using microbubble dynamic auxiliary separate mode, keeps the dissolved oxygen concentration in waste water, constantly to
Supplement activity oxygen in water, solves the fermentation of natural subsidence sludge anaerobic and produces humic acid, breath malodor, seriously affects surrounding environment
Outstanding problem, while only less sludge is in bottom deposit, 70% above by microbubble rise to oil slick slag accumulation regions from
Dynamic discharge, thoroughly solves base sludge accumulation, and the runner that results in blockage, be difficult to remove, take dischargeable capacity, influence effluent quality
A series of problems, such as, separated by system, water outlet oil content, which can reduce by more than 98%, SS contents, can reduce by more than 97%, significantly
Improve water-oil separating treatment effect.
