Description

Technical Field

[0001] The utility model relates to the technical field of composite carbon source preparation, in particular to a preparation device for a composite carbon source for sewage denitrification. Background Art

[0002] Wastewater denitrification is the process of denitrifying wastewater to prevent eutrophication of water bodies. It is generally divided into two methods: physical and chemical method and biological denitrification method. Composite carbon source is a highly efficient transparent liquid carbon source developed for wastewater treatment. It has the characteristics of non-toxicity, green, high conversion rate, high concentration, etc. A preparation device for composite carbon source for wastewater denitrification is required in the preparation of composite carbon source.

[0003] A Chinese patent with authorization announcement number CN217287481U discloses a device for preparing a composite carbon source for biological denitrification of sewage, including a filter barrel, a fixed frame connected to the top of the filter barrel, a support column for supporting the filter barrel connected to one side of the filter barrel, and a cleaning component for cleaning the sludge at the bottom of the filter barrel is arranged in the fixed frame. After the staff obtains the raw materials by using the filter barrel, they can start the motor to drive the rotating column to rotate, thereby driving the scraper at the bottom to stir the sludge at the bottom of the filter barrel, and separate the clogged sludge on the surface of the filter screen from the filter screen, thereby preventing the filter screen from being clogged by solid impurities.

[0004] Although the above-mentioned composite carbon source preparation device can separate the blocked sludge on the surface of the filter from the filter, thereby preventing solid impurities from clogging the filter, the existing device generally only has the effect of removing impurities on the filter. After the impurities are scraped off by the scraper, they still exist inside the box. If they exist in the box for a long time, it is easy to affect the preparation effect of the composite carbon source. For this reason, we propose a preparation device for a composite carbon source for sewage denitrification. Utility Model Content
