However, since the low-ammonia nitrogen silver powder wastewater wants to biologically separate the low-ammonia nitrogen silver powder inside through the biological film, sufficient oxygen is required for the reaction. However, the oxygen carried by the wastewater itself or the biological contact disk is exposed to the air, the oxygen mixing efficiency is too low, which can easily lead to the problem of untimely reaction. In addition, during the reaction process of the biological reaction disk, the disk body is prone to scaling, resulting in blockage, which is not conducive to replacement.

[0004] Therefore, we provide a low ammonia nitrogen silver powder wastewater high-efficiency rotary biological contactor to solve the above problems. Utility Model Content

[0023] Example 1

[0024] See also Figure 1-4 As shown, the utility model provides a technical solution: a high-efficiency rotary biocontactor for low-ammonia-nitrogen silver powder wastewater, comprising a body 1 and a biocontactor 2, wherein the biocontactor 2 is installed inside the body 1;

In this way, through multiple groups of series connection, disassembly and maintenance can be carried out more quickly, and the operation effect is better. At the same time, since the contact chamber 221 is only slightly larger than the contact sheet frame 225, there is no need to worry about affecting the filtering reaction.

[0028] Furthermore, the bacteria contact film 226 and the contact film frame 225 are adhesively connected, and the bacteria contact film 226 and the contact film frame 225 are set in a one-to-one correspondence. When needed, the use of multiple groups of bacteria contact films 226 can effectively reduce the problem of incomplete filtration caused by a single group of bacteria contact films 226.

[0031] Example 2

[0032] See also Figure 1 、 Figure 2 and Figure 4 As shown, in contrast to Example 1, as another embodiment of the present invention, a discharge assembly 3 is installed on the lower side of the body 1, and the discharge assembly 3 includes a storage bin 31, a storage port 32 and a water outlet pipe 33. The storage bin 31 is welded on the lower side of the body 1, and the inner side of the storage bin 31 is provided with a storage port 32. The left side of the storage bin 31 is welded with a water outlet pipe 33. When the scraper 232 scrapes off the deposits, it will fall into the storage port 32 in the storage bin 31, so that the deposits can be collected, avoiding secondary filtration of the deposits and increasing work intensity, and the filtered wastewater is discharged through the water outlet pipe 33.

[0033] Working principle: A low-ammonia-nitrogen silver powder wastewater high-efficiency rotary biological contactor is moved to the working position. When in use, the first step is to connect the water inlet pipe 212 to the wastewater discharge equipment at the outer end, and then install the body 1 to the position where it needs to be used. The second step is to turn on the slow water inlet pump 211 and pump the wastewater into the body 1 through the water inlet pipe 212. As the wastewater is pumped in, the contact sheet frame 225 in the contact chamber 221 will be driven by the rotating motor 222, and the bacteria contact film 226 will start to rotate along the contact chamber 221 one by one, and the rotating rod 223 and the connecting screw sheet 224 will move multiple groups of contact sheet frames 225. Combined, the wastewater will then pass through the bacteria contact film 226 to achieve the effect of biological contact filtration. In the third step, the air inlet pipe 245 inputs air into the oxygen chamber 241 through the ventilation pipe 243 via the air pump 244, and the oxygen will be injected into the contact chamber 221 through the oxygen port 242 to provide biological bacterial reaction. As the biomass accumulates, the scraper 232 on the support frame 231 will scrape off the accumulated biomass and fall into the storage port 32 in the storage bin 31, and the filtered wastewater is discharged through the outlet pipe 33. This completes the use process of a low-ammonia nitrogen silver powder wastewater high-efficiency rotary biological contactor.
