Description

Modularized container type protein wastewater treatment equipment Technical Field The invention relates to the technical field of sewage treatment, in particular to modularized container type protein wastewater treatment equipment for solid-liquid separation of sewage. Background In the industrial production processes of food processing, biopharmaceutical production, slaughter and breeding, and the like, a large amount of high-concentration protein wastewater can be generated. The wastewater is rich in pollutants such as protein, suspended matters, grease and the like, and if the wastewater is directly discharged, serious water eutrophication can be caused, and the ecological environment is destroyed, so that the wastewater can be discharged after strict treatment. At present, the modularized container type sewage treatment equipment is widely applied to protein wastewater treatment scenes because of the advantages of convenient installation, small occupied area, flexible migration and the like. The solid-liquid separation technology takes an air floatation method as a core, and releases micro bubbles into sewage to enable the bubbles to be adsorbed on the surface of flocculated flocs, the flocs are driven to float upwards by buoyancy, and suspended matters are removed by a slag scraping device, so that sewage purification is realized. However, the existing modular container type protein wastewater treatment equipment still has significant defects in practical application: The protein wastewater suspension contains hard particles such as sand stone, metal scraps and the like, and also contains a large amount of viscous impurities such as grease, colloid, viscous sludge and the like. The impurities are easy to block the air outlet channel of the microbubble releaser, so that the release amount of the microbubble is reduced sharply and distributed unevenly, the combination efficiency of the floccule and the bubbles is seriously affected, the solid-liquid separation effect is further reduced, the shutdown, disassembly and cleaning are needed after the blockage, the sewage treatment flow is frequently interrupted, and the treatment efficiency is greatly reduced. The releaser is suitable for single scene, and the existing device microbubble releasers are mostly designed in a single structure and can only deal with sewage of certain impurity type. The releaser to the hard particle jam can't effectively handle viscidity impurity, and be applicable to viscidity impurity's releaser again easily by hard particle damage, be difficult to adapt to the processing demand of different grade type protein waste water, restricted the application scope of equipment. The solid-liquid separation efficiency is insufficient, the microbubble release direction of the partial releaser is single, the coverage range is limited, the contact probability of the bubble and the floccule in the sewage is low, the floccule floating rate is low, the floating rate is insufficient, the sewage purification period is prolonged, and the treatment capacity is difficult to meet the continuous emission requirement of industrial production. Therefore, the modularized container type protein wastewater treatment equipment with the high-efficiency anti-blocking function, wide application range and excellent solid-liquid separation effect is developed, and becomes a key requirement for solving the pain point of the current industry.
