Description
Technical Field
The utility model relates to a sewage treatment technical field specifically is sweet potato waste water integration sewage treatment device.
Background
Sweet potato, also known as sweet potato and sweet potato. Sweet potatoes are easy to rot and are not suitable for long-term storage. The deep processing of the sweet potato can solve the phenomenon of rotten sweet potato caused by improper storage of fresh sweet potato, and the refined sweet potato starch can produce hundreds of valuable chemical products through processing at different depths, with the added value of about 10-30 times, considerable prospect and huge market potential. At present, more than 1000 starch production enterprises in China have annual output of 600 ten thousand tons, and according to the existing processing technology, about 6 tons of high-concentration organic wastewater is produced per 1 ton of starch produced, so that the whole starch manufacturing industry produces much wastewater annually. The waste water mainly contains soluble starch, a small amount of protein, organic acid, dust, mineral substances and a small amount of grease, is easy to decay and ferment, blackens and smells water quality, consumes dissolved oxygen in water when being discharged into rivers, promotes the propagation of algae and aquatic plants, seriously lacks oxygen in the rivers when the amount is large, generates anaerobic decay, emits foul odor, and can cause the death of aquatic animals such as fish, shrimps, shellfish and the like in a room. And thus are receiving increasing attention from environmental scientists.
The existing sweet potato production sewage treatment process is complex, the treatment effect is not ideal, and the discharge does not reach the standard.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in figure 1, sweet potato waste water integration sewage treatment device, including aeration equalizing basin 1, flocculation and precipitation pond 2, hydrolysis-acidification pond 3, contact oxidation pond 4, MBR pond 5 and clean water basin 6 that communicate in proper order, hydrolysis-acidification pond 3 and contact oxidation pond 4 still communicate there is biological intensification retort 7, contact oxidation pond 4 and MBR pond 5 drain all are linked together with flocculation and precipitation pond 2, 2 sludge outlet intercommunications in flocculation and precipitation pond have mud saving pond 8, 8 sludge outlet in mud saving pond is linked together with sludge thickening jar 9, 9 sludge outlet in sludge thickening jar communicate with filter-pressing sheet frame device 10, 2 medicine adding mouth positions of flocculation and precipitation pond communicate there is acid-base medicine adding equipment 11, acid-base medicine adding equipment 11 medicaments are one or more of PAC and PAM.
The working principle is as follows: the sweet potato starch wastewater is introduced into an aeration adjusting tank 1 through a water pump for aeration, a medicament is added through an acid-base dosing device 11, then precipitation treatment is carried out through a flocculation sedimentation tank 2, sludge at the bottom of a pit of the starch wastewater is utilized by a biological enhancement reaction tank 7, three high-efficiency degradation bacteria of escherichia coli, pseudomonas and bacillus are obtained through a screening technology, after 24 hours of aeration culture, a high-efficiency degradation microbial inoculum is obtained through enlarged culture, microbial enhancement is carried out by utilizing the high-efficiency degradation bacteria, then a filtrate filtered by the flocculation sedimentation tank 2 is added, anaerobic treatment is carried out through a hydrolysis acidification tank 3, then aerobic contact oxidation treatment is carried out through a contact oxidation tank 4, a supernatant is separated, and sludge deposition in the hydrolysis acidification tank 3 and the contact oxidation tank 4 is introduced into the flocculation sedimentation tank 2 through a conduit for precipitation treatment again; combining high-efficiency degradation bacteria of the refractory organic pollutants obtained by manual screening with the modified high-efficiency filler, intercepting and increasing the concentration of microorganisms in the wastewater, improving the degradation effect, transferring the supernatant to an MBR (membrane bioreactor) tank 5 to further improve the water quality, diluting the separated impurities, and introducing the diluted impurities into a flocculation sedimentation tank 2; the filtered clear water is introduced into a clear water tank 6 to be discharged after reaching the standard; the membrane separation equipment is directly placed in the aerobic reactor to reduce the interception of activated sludge and macromolecular organic substances. Compared with the traditional activated sludge method, the method saves a secondary sedimentation tank, shortens the hydraulic retention time, improves the treatment efficiency, reduces the capital investment and the operating cost, transfers the sediment at the bottom of the flocculation sedimentation tank 2 to a sludge storage tank through a conduit, then carries out concentration through a sludge concentration tank 8, and separates solid from liquid through a plate-and-frame filter pressing device 10.
