Description

Technical Field

[0001] The utility model relates to the technical field of organic wastewater treatment, in particular to an organic wastewater treatment device. Background Technique

[0002] Organic wastewater is wastewater mainly containing organic pollutants. Organic wastewater is likely to cause water eutrophication and has relatively great harm. The hydrolysis treatment method is a method between aerobic and anaerobic treatment methods. Combining with other processes can reduce the treatment cost and improve the treatment efficiency. In industrial wastewater generated in fields such as chemical industry and food processing, there are organic substances such as carbohydrates, oils and fats, and proteins. These substances exist in the wastewater in a suspended or dissolved state. Generally, when treating wastewater, first, through mechanical treatment, large impurities in the water are removed by filtration and precipitation methods, and then biological treatment is carried out. During biological treatment, pollutants in the wastewater are degraded and converted into sludge under the action of microorganisms. Finally, deep treatment is carried out to remove nutrients in the wastewater, and then the treated wastewater is disinfected by ultraviolet radiation or ozone technology, so as to meet the discharge or secondary utilization standards.

[0003] At the present stage, two problems will be encountered:

[0004] 1. When in use, sewage flows into the sedimentation tank through the water inlet pipe for sedimentation. The sewage treated by the sedimentation tank reacts in the vertical anaerobic tank. The precipitated impurities are discharged through the outlet provided at the bottom of the hopper-shaped structure. However, the precipitated sludge aggregates together after long-term sedimentation, blocking the outlet and making it difficult to clean the impurities completely.

[0005] 2. A lot of dead sludge and oil films will float on the surface of organic wastewater. The floating dead sludge and oil films will adhere to the inner wall of the acidification tank, affecting the hydrolysis treatment. And when treating organic wastewater at present, acidifying liquid needs to be added to the organic wastewater. The commonly used method at present is to make the wastewater and the liquid mix through a third-party independent air pipe, and the mixing effect is poor, affecting the treatment effect of organic wastewater.
