Description

Technical Field

[0001] The utility model relates to an ammonia nitrogen wastewater treatment device. Background Art

[0002] There are many methods to remove ammonia nitrogen from industrial wastewater. The mainstream technologies include: ammonia stripping, membrane separation, chemical precipitation, ion exchange, breakpoint chlorination, biological denitrification, etc.

[0003] At present, there are many electrolysis devices that use electrolysis to remove ammonia nitrogen. For example, the Chinese utility model patent with publication number CN208279439U discloses a high-salt organic ammonia nitrogen wastewater electrolysis treatment device, which achieves the purpose of improving the electrolysis efficiency by filling the electrolysis box with conductive fillers. However, due to the presence of the filler, the wastewater has low fluidity, resulting in a decrease in the contact rate with chloride ions, resulting in a problem of low electrolysis efficiency. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an ammonia nitrogen wastewater treatment device.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] An ammonia nitrogen wastewater treatment device comprises a sewage pool, an electrolytic assembly covered on the sewage pool, the electrolytic assembly comprises a cement plate covered on the sewage pool, anode electrolytic rods and cathode electrolytic rods installed in sequence and staggered below the cement plate, a controller fixed on the surface of the cement plate and connected to the anode electrolytic rods and the cathode electrolytic rods respectively through wires, a sewage inlet installed at one end of the cement plate, and a water outlet pipe located below the cement plate and connected to the sewage inlet.

[0007] Preferably, hooks are installed equidistantly on both sides of the bottom of the cement board.

[0008] Preferably, the anode electrolysis rod is bent in a U shape.

[0009] Preferably, the anode electrolysis rod is also provided with spiral fins.

[0010] Preferably, the structure of the cathode electrolysis rod is consistent with that of the anode electrolysis rod.

[0011] Preferably, the water outlet pipe is horizontally placed above the anode electrolysis rod and the cathode electrolysis rod, and water outlet holes are opened on both sides of the water outlet pipe.

[0013] Furthermore, a filter plate slot is provided on the drain outlet, and clamping edges extend from both ends of the filter plate.

[0014] The utility model can effectively degrade and treat impurities in ammonia nitrogen wastewater through the electrolysis process between the anode electrolysis rod and the cathode electrolysis rod, so as to purify it. Since the anode electrolysis rod is provided with spiral fins, the contact area between the anode electrolysis rod and the sewage is increased, and the electrolysis efficiency is improved. In addition, the controller can automatically adjust the working state of the anode electrolysis rod and the cathode electrolysis rod, so as to realize automatic operation. Furthermore, the device is also equipped with a filter plate and a drain port for separating solid impurities in the wastewater to ensure the quality of the effluent. Therefore, the whole device has a simple and compact structure and is easy to install, and also the treatment efficiency of the ammonia nitrogen wastewater is improved.
