Background
High concentration means that the wastewater contains more organic matters, and is characterized by higher COD value, often too much. The standard discharge of the wastewater can not be achieved by simply relying on aerobic biological treatment. The high ammonia nitrogen means that the water contains NH 4+ Higher, it has very strong inhibition effect on anaerobic methanogenesis process. Difficult to descendThe solution means that the components in the wastewater which can be directly utilized by microorganisms are fewer, the B/C value is lower, the wastewater is not suitable for being treated by a biochemical method, and pretreatment is often needed to improve the biochemical property of the wastewater. Water treatment workers have been studied for many years, and more mature processes exist for treating industrial wastewater with the characteristics of the single aspect. The landfill leachate is a water body with high concentration of organic matters and high salinity, and the treatment difficulty is quite high. Fenton is a mainstream organic matter removal process, and when facing landfill leachate, has the pain points of low efficiency and high operation cost. By Fe 2+ /H 2 O 2 Fenton reaction is mainly carried out by Cu 2+ /H 2 O 2 The Fenton reaction is enhanced by the design of a plurality of factors such as a reaction system, coagulating sedimentation, micro aeration, active carbon adsorption and the like, and the capacity of removing organic matters is increased, so that the Fenton reaction can be used as a normal process for deep treatment of landfill leachate, the requirement of water outlet is met, and the load of Fenton organic matters is reduced. The coagulating sedimentation tank is one of sedimentation tanks in wastewater treatment. The coagulation process is the most basic and extremely important treatment process in industrial water and domestic sewage treatment, and by adding some medicaments (commonly called coagulants and coagulant aids) into water, particles which are difficult to precipitate in the water can be mutually polymerized to form colloid, and then the colloid is combined with impurities in the water body to form larger floccules. The floccule has strong adsorption force, and can adsorb suspended matters, partial bacteria and soluble matters. The flocculating constituent is absorbed, the volume is increased and sunk, so that partial organic matters are removed, the chromaticity is reduced, the Fenton operation load is reduced, the medicament is uniformly dispersed in the sewage, the flocculating constituent efficiency and effect can be improved, the medicament is directly added into the sewage, the partial concentration of the medicament is excessively high, the medicament waste and the flocculating settling efficiency are reduced, however, the conventional high-concentration ammonia nitrogen treatment device cannot solve the problems, and the medicament cannot be uniformly added into the sewage.
