Description
Technical Field
The invention belongs to the technical field of water purification, and particularly relates to a hydraulic spin biological membrane purification system for a small micro water body and a working method thereof.
Background
Due to excessive fertilization and industrial production activities, a large amount of nitrogen-containing compounds enter small micro-water bodies such as rivers and lakes with poor self-cleaning capability, however, when the ammonia nitrogen content in the small micro-water bodies is too high, a series of serious environmental problems such as water eutrophication, reduction of aquatic organism diversity and the like are caused, and finally, the influence on the life health and safety of human beings is generated. At present, ammonia nitrogen becomes a parameter index which is primarily examined in water pollution in China. According to the research in recent years, the occurrence frequency of ammonia nitrogen in surface water body out-of-standard pollutants in China is very high, and the trend of increasing year by year is shown, for example, the ammonia nitrogen content of other water systems except for Zhujiang and Changjiang in seven water systems exceeds the ammonia nitrogen limit value (0.5 mg/L) in sanitary Standard for Drinking Water (GB 5749-2006), and in addition, the ammonia nitrogen content in water systems in a plurality of places in China is above 4mg/L, and even reaches 50.4mg/L at most. Therefore, the problem of ammonia nitrogen pollution in surface water is solved, and the method becomes important content in the field of water treatment in China.
The pollution control technology currently available for small micro water bodies with too high nitrogen content mainly comprises a physical method, a chemical method and a biological method. From the viewpoints of thoroughly eliminating nitrogen pollution and reducing economic cost, the heterotrophic nitrification and aerobic denitrification process by a biological method is most reasonable in the technologies. The process can use organic carbon as an electron donor, resulting in a higher nitrification-denitrification rate. However, the lack of available carbon sources is a worldwide problem in the heterotrophic nitrification aerobic denitrification of small micro-bodies of water with low carbon to nitrogen ratios. At present, the research on the carbon source adopted by the heterotrophic nitrification-aerobic denitrification process is mainly focused on the deep development and utilization of the system carbon source and the accurate addition control aspect of the traditional additional carbon source, and the research and engineering application of the emerging slow-release carbon source to promote the characteristics of nitrification-denitrification are less. In addition, the water body is generally purified by adding a slow-release carbon source, and the polluted water body such as rivers and lakes is easy to run off, the contact area time is short, and the purifying effect is poor. The slow-release carbon source is used as a material and is used as a carrier for the growth of a biological film to promote the biological removal of pollutants, and the slow-release carbon source can also be used for providing a carbon source for a water body with a low carbon nitrogen ratio, so that the removal rate of nitrogen in the water body is improved. Based on the background, the invention provides the biological film filler hydraulic spinning device with the carbon source slow-release function, so that the water quality of the small micro water body is purified and improved.

The working method of the hydraulic spin biological film purifying system for the small micro water body is characterized by comprising the following steps of:
s1: the grid module 4 firstly filters out dead branches, rotten leaves and large broken stones and weakens the impact of water flow on the biofilm packing 305, and protects the hydraulic spinning device 304; when more impurities are accumulated on the surface of the grid module 4, the electric telescopic rod 8 starts to work to drive the grid module 4 to move so as to shake off the impurities on the surface of the grid module 4, so that the impurities are prevented from accumulating on the surface of the grid module 4 and prevent water from flowing into the purification system;

Application characteristics of JC biofilm packing in a system: light weight, floatability, light weight, impact resistance and floatability, energy conservation and freight and running cost saving; environmental protection, no pollution and no chemical residue; the film forming performance is good, the porosity is high, the specific surface area is large, and the bacterial growth is facilitated; the film forming speed is high, the biocompatibility is good, and the film forming time is shortened to 7-15 days; oil resistance, drug resistance, stable material, acid resistance, alkali resistance, aging resistance and biodegradation resistance.
The nitrogen removal rate of the biofilm carrier (JC) prepared from polyvinyl alcohol and sodium acetate is compared with that of the biofilm carrier made from conventional materials (polyvinyl alcohol and starch) as shown in FIG. 12. Adding 5g of slow-release carbon source biomembrane filler (the proportion of the used filler raw materials is that of polyvinyl alcohol: starch=1:1)) into a reactor, then adding 100mL of domesticated activated sludge and 400mL of test water (50 mg/L of simulated nitrogenous wastewater), sealing a bottle mouth by using a sealing film, and keeping the anoxic environment in the reactor. And placed in a shaking box at a set speed of 70rpm for culture reaction. And measuring and calculating the removal rate of nitrogen in the nitrogen-containing wastewater after 24 hours, and replacing the nitrogen-containing wastewater in the reactor every 24 hours without replacing slow-release carbon source biofilm filler in the reactor. The experiment was continued for 20 days. Comparison experiments are carried out by adopting sodium acetate to replace starch under the same test conditions, and the comparison of the nitrogen removal rate of the novel biological film filler (JC) prepared by polyvinyl alcohol and sodium acetate and the conventional biological film filler prepared by polyvinyl alcohol and starch in the range of 20 days shows that the nitrogen removal rate of the novel biological film filler of JC is always above 85 percent and can reach 95 percent; the nitrogen removal rate of the conventional biological film filler prepared from the polyvinyl alcohol and the starch which are commonly used at present is far better than that of the conventional biological film filler, so that the biological film filler can play an important forward pushing role in purifying the water quality of small and micro water bodies when being used in the system.
