Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a papermaking machinery wastewater treatment system. Background Art

[0002] Papermaking wastewater discharge is large, and the main problem to be solved is to remove SS and COD. For example, color paper wastewater also has color problems. The problems of papermaking wastewater in the industry are: 1. High chromaticity of the effluent. The reason is: the lignin and its derivatives dissolved in the production process make the wastewater have a range of colors from light brown to dark brown. The biodegradation of these compounds is very slow, and the biochemical treatment effect is poor. The secondary biochemical method can remove up to 30% of the chromaticity in the wastewater; 2. The water volume exceeds the facility's processing capacity.

[0003] Ammonia nitrogen in wastewater is usually removed by nitrification reaction between solution and wastewater. The existing wastewater treatment mechanism has a relatively simple structure, and cannot effectively carry out centralized nitrification treatment of the imported wastewater during the processing process, and the operability is poor; and the impurities retained in the existing device are inconvenient to discharge, which is easy to cause internal blockage.
