Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage management system for toilet paper production. Background Art

[0002] The papermaking industry is a highly energy-intensive and environmentally polluting industry. Its environmental pollution is characterized by large wastewater discharge volumes, high biochemical oxygen demand (BOD), and high levels of suspended solids in the wastewater, primarily containing hemicellulose, lignin, inorganic acid salts, fine fibers, inorganic fillers, inks, dyes, and wastewater and exhaust gases containing divalent sulfur.

[0003] At present, when treating papermaking wastewater, the three main stages of physical treatment, chemical treatment and biological treatment are usually followed, and each stage has its own large treatment pool. The existing treatment pools are usually fixed, and according to the progress of papermaking, wastewater treatment is also divided into peak and trough periods, which are located in different periods. If the same treatment pool is still used for treatment, especially chemical treatment, the main purpose is to remove dissolved organic matter and color in the wastewater. This stage usually requires the addition of coagulants, and time is also required for mixing and reaction, so as to remove most of the SS and insoluble COD, partially soluble COD, and BOD. When facing wastewater of different magnitudes, the efficiency of mixing and reaction will also be different. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned deficiencies and provide a sewage management system for toilet paper production.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model divides the filter pool into two and the degradation pool into multiple pools. When filtering, one of the filter pools is used first, and after long-term use, it is replaced with another filter pool. In this way, the original filter pool can be inspected and cleaned, and the continuity of wastewater treatment is maintained. The multiple sub-pools can be adjusted according to the amount of sewage. When the flow is large, multiple sub-pools are used for treatment. Compared with the total pool, the capacity of each sub-pool is smaller. When treating sewage, it can be kept within a certain volume. In this way, when adding coagulant, it is helpful for the mixing and reaction of the coagulant, thereby improving efficiency. When the total amount of sewage is small, some of the sub-pools can also be closed to improve the utilization efficiency of resources. By providing an MVR evaporator for evaporating and crystallizing the treated sewage, a wastewater treatment effect with high recovery rate and low energy consumption is achieved.
