Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, relates to a treatment technology for organic wastewater, and specifically is an organic sewage anti-shock treatment system. Background Art

[0002] Organic wastewater refers to wastewater primarily composed of organic pollutants. Organic wastewater can easily cause eutrophication and poses significant risks. Therefore, organic wastewater generally requires treatment before discharge. Existing organic wastewater is primarily treated through biochemical decomposition by microorganisms. Patent application number CN200610020454.0 discloses a method for treating high-concentration organic wastewater. The method includes the following steps: desanding and deslagging the organic wastewater; flocculation and sedimentation separation; and further electrolytic oxidation degradation of the organic wastewater in an integrated degradation tank. Following sedimentation separation in a clarifier, the sludge is incinerated and the catalytic oxidant is regenerated for recycling. The wastewater then undergoes microbial degradation and electrochemical treatment in a post-treatment tank, followed by sedimentation separation, resulting in discharge of qualified water or recycling. This patent document primarily involves desanding and deslagging the organic wastewater; flocculation and sedimentation separation (pretreatment), followed by microbial degradation, catalytic oxidation, and electrolytic oxidation degradation, resulting in the organic wastewater being converted into qualified water for recycling. During the organic wastewater treatment process, microbial degradation requires high temperatures. To maintain degradation efficiency, the temperature of the organic wastewater must be neither too high nor too low. However, during actual treatment, the quality and temperature of the water entering the organic wastewater treatment system can sometimes fluctuate significantly, impacting the system's native ecosystem and affecting the efficiency and quality of the treatment. For example, if the water quality suddenly entering the organic wastewater treatment system is too poor, exceeding the system's treatment capacity, resulting in poor treatment quality; or if the water temperature suddenly entering the organic wastewater treatment system is too high, microbial activity is reduced, resulting in low treatment efficiency. Utility Model Content

[0003] In view of the above, during the actual treatment process of organic wastewater discharged into the organic wastewater treatment system, the water quality and water temperature sometimes fluctuate greatly, causing impact on the original ecosystem of the organic wastewater treatment system and affecting the treatment efficiency and quality of the organic wastewater.

[0004] The utility model adds a buffer tank to the organic sewage pipeline of the organic sewage treatment system. When the water quality or water temperature of the organic sewage in the organic sewage pipeline fluctuates greatly, the organic sewage in the organic sewage pipeline is discharged into the buffer tank. Subsequently, the organic sewage in the buffer tank is appropriately added to the organic sewage treatment system within the treatment capacity of the organic sewage treatment system for treatment, thereby avoiding impact on the original ecosystem of the organic sewage treatment system, maintaining the dynamic balance of the organic sewage treatment system, ensuring the stability of the organic sewage treatment system, and avoiding affecting the biochemical treatment efficiency and treatment quality of the organic sewage.
