Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a lime feeding device for wastewater treatment. Background Technology

[0002] The method of treating steel wastewater with lime mainly includes the following steps: 1. Adjusting the pH value: Add lime (mainly calcium oxide or calcium hydroxide) to the wastewater to adjust the pH value to the alkaline range (usually controlled between 8-10), so that iron ions form insoluble ferric hydroxide precipitates, thereby achieving iron removal precipitation and filtration; 2. The generated ferric hydroxide precipitates can be separated from the wastewater by precipitation and filtration to obtain purified water. Lime treatment of steel wastewater: Lime (mainly calcium oxide or calcium hydroxide) reacts chemically with heavy metal ions (such as iron ions) in wastewater to generate insoluble metal hydroxide precipitates. These precipitates can be separated from the wastewater by physical methods such as precipitation and filtration, thereby achieving the purpose of removing heavy metals.

[0003] A search revealed an existing patent (CN208250053U) that discloses a wastewater reuse system for the steel industry. The system includes a homogenizing tank, a Fenton oxidation tank, a flocculation reaction tank, a neutralization and equalization tank, and a multi-media filter tower, all connected in series via pipelines. A Fenton reagent dosing tank is located above the Fenton oxidation tank, and a distributor is located at the top of the Fenton oxidation tank, connected to the Fenton reagent dosing tank via pipelines. A water distribution cylinder is coaxially positioned below the distributor within the Fenton oxidation tank, and multiple distribution holes are provided on the water distribution cylinder. Water holes; the bottom end of the water distribution cylinder is equipped with an inlet pipe connected to the homogenization tank, and a high-pressure pump is installed on the inlet pipe; this utility model sets up a Fenton oxidation tank, which uses acidic steel industry wastewater containing a large amount of Fe2+ ions for Fenton oxidation, which can remove a variety of organic matter in the wastewater and generate Fe3+ ions, providing flocculant raw materials for subsequent flocculation reactions. In addition, the Fenton oxidation tank is equipped with a water distribution cylinder and a liquid distributor, which allows the wastewater and Fenton reagent to move relative to each other, resulting in a large contact area and rapid reaction. This not only avoids the drawbacks of dead corners caused by mechanical stirring, but also enables efficient reaction.
