Description
Technical field
The utility model relates to a kind of water treatment system, is specifically related to a kind of oil-contained waste water treatment system.
Background technology
Oily(waste)water refers to the oils organism containing higher concentration in waste water, if directly discharged, can cause severe contamination, also can form serious threat to the health of mankind itself.Organic pollutant, especially high concentration organic contaminant, in water, lifetime is long, migration circle is wide, and harm is large, intractability is high.The removal of high concentration organic contaminant is an important subject of field of Environment Protection always.Shortage of water resources has become the important factor of restriction China's economy and social development.Industry water withdrawal accounts for 20% of national water withdrawal, for strengthening Industrial Water Saving work further, alleviate the imbalance between supply and demand of China's water resources, the impetus of containment water environment degradation, promote the coordinated development of industrial economy and water resources and environment, " the Chinese water-saving technology policy outline " within 2005, promulgated first proposed the requirement of development efflux wastewater reuse and " zero release " technology.New " the national environmental protection Eleventh Five-Year Plan " promulgated of in November, 2007 country more explicitly calls for popularization cycling utilization of wastewater, strives for waste water and discharges less or zero release.In order to the water saving that responds to the call of one's country, simultaneously protection of the environment, save enterprise's production cost, necessary clean is carried out to textile waste, realizes water resources recycle.
Summary of the invention
The utility model object provides a kind of oil-contained waste water treatment system to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of oil-contained waste water treatment system, it comprises for collecting oily(waste)water and collecting tank to its stratification, the Buffer Pool be connected with described collecting tank for collecting oil reservoir, the air-floating apparatus be connected with described collecting tank for collecting water layer, the reuse water tank be connected with described air-floating apparatus, the coagulation basin be connected with described Buffer Pool, be connected with described coagulation basin and combine pond for A/O oil reservoir being carried out to biological denitrificaion process, the flocculation basin that pond is connected is combined with described A/O, be connected with described flocculation basin for the settling tank staticly settled, described settling tank is also connected with described reuse water tank.
Optimally, it also comprises the air flotation pool be communicated between described Buffer Pool and described coagulation basin.
Further, it also comprises and is communicated in described coagulation basin and described A/O and combines upflow anaerobic sludge blanket process between pond.
Further, it also comprises the water collecting basin be communicated between described settling tank and described reuse water tank.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model oil-contained waste water treatment system, collecting tank is set on the one hand for collecting oily(waste)water and to its stratification, and be communicated with respectively in its downstream Buffer Pool and air-floating apparatus are set, thus respectively differentiated treatment is carried out to the water layer of standing generation and oil reservoir, thus improve the treatment effect of sewage; Set gradually on the other hand the coagulation basin, the A/O that are connected and combine pond, flocculation basin, settling tank, and settling tank is connected with reuse water tank, thus oil reservoir is carried out sufficient biological respinse be degraded into small organic molecule and precipitation, realize the recycling to waste water.

Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Oil-contained waste water treatment system as shown in Figure 1, mainly comprises collecting tank 1, Buffer Pool 2, coagulation basin 4, A/O combination pond 6, flocculation basin 7 and settling tank 8.
Wherein, collecting tank 1 for collecting oily(waste)water, and carries out layering to oily(waste)water thus produces the water layer and oil reservoir that are separated.Buffer Pool 2 is connected with the top of collecting tank 1, for collecting in collecting tank 1 oil reservoir swimming in top.Air-floating apparatus 10 is connected with the bottom of collecting tank 1, and for collecting in collecting tank 1 water layer sinking to below, it can remove the elaioleucite suspended in most of water layer.Reuse water tank 11 is connected with air-floating apparatus 10, for storing the water layer after air-floating apparatus 10 processes.Coagulation basin 4 is connected with Buffer Pool 2, first can add a certain amount of alkali lye wherein, make the grease generation saponification reaction in alkali lye and oil reservoir when the oil reservoir in Buffer Pool 2 imports in coagulation basin 4, then adds the coagulating agent such as a certain amount of PAC and staticly settle.A/O combines pond 6 and is connected with coagulation basin 4, for receiving the supernatant liquor produced in coagulation basin 4, thus carries out biological denitrificaion process to the oil ingredient in this supernatant liquor.Flocculation basin 7 and A/O combine pond 6 and are connected, and by adding the coagulating agent such as a certain amount of PAC, PAM or flocculation agent wherein, can remove the fixing impurity in the waste water of biological denitrificaion process.Settling tank 8 is connected with flocculation basin 7, and for staticly settling, it is also connected with reuse water tank 11, thus is imported in reuse water tank 11 by the supernatant liquor produced, and reclaims for subsequent use.
