Total Phosphorus Removal from Lithium Battery Industry Wastewater-Adsorption

According to the characteristics of the industry, biological phosphorus removal process and chemical phosphorus removal process are selected for industrial wastewater. However, the types of phosphorus pollution sources and wastewater components in high salt industrial wastewater are different, and specific phosphorus removal processes need to be studied for each type of wastewater.

The precursor industry of new energy lithium battery cathode materials is a new industry, and the wastewater discharged from the precursor industry of lithium battery cathode materials comes from the production process of synthetic raw materials such as nickel salts, cobalt salts, and manganese salts.

The raw material used in the production process is ore, and the auxiliary materials include acid and alkali, oxidants, and extractants. According to the analysis of production processes and raw materials, the main component of phosphorus in wastewater is organic phosphorus, which mainly comes from the extractants in the extraction and purification process.

When using Haipu's adsorption process to treat organic phosphorus wastewater, the wastewater is pre filtered to remove suspended and particulate matter, and then enters the adsorption tower for adsorption. The special adsorption material filled in the adsorption tower can adsorb the organic phosphorus in the wastewater on the surface of the material.

After adsorption saturation, specific desorption agents are used to desorb the adsorbent material, allowing it to regenerate. This process is continuously repeated, and the adsorbed water can be directly sent to the biochemical system for treatment.
