Resource Utilization Treatment Method for Ortho Aminobenzoic Acid Wastewater

In industrial production, various types of organic wastewater are generated. The treatment of ortho aminobenzoic acid wastewater has high toxicity, high compound content, high COD concentration, and is difficult to degrade. If directly discharged, it will cause great pollution to the environment and also have an impact on human health. At present, adsorption recovery method is mainly used for the treatment of ortho aminobenzoic acid wastewater.

Haipu customized treatment process for ortho aminobenzoic acid wastewater

Jiangsu Haipu Functional Materials Co., Ltd. is committed to the research and industrialization of high-performance adsorbents and catalysts. In 2018, it was approved as the Suzhou Adsorption and Catalytic Functional Nanomaterials Engineering Technology Research Center. Through years of independent research and development, it has achieved international leading levels in ion exchange technology and adsorption technology, nano inorganic material hybridization technology, etc., realizing the serialization of adsorption and catalytic products and successfully applying them in the fields of environmental protection and resource recycling. With a series of independently developed high-performance adsorbents and catalysts as the core, combined with self-developed process technology, Haipu has become a professional supplier of green and environmental protection solutions.

The adsorption process for ortho aminobenzoic acid wastewater developed by Jiangsu Haipu Functional Materials Co., Ltd. adsorbs and recovers the vast majority of ortho aminobenzoic acid in the wastewater, and the adsorbed water contains almost no ortho aminobenzoic acid, ensuring subsequent discharge or reuse requirements.

When using Haipu's adsorption process to treat 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 ortho aminobenzoic acid substance in the wastewater on the surface of the material. After adsorption saturation, a specific desorption agent is used to desorb the adsorption material, achieving the recovery and separation of ortho aminobenzoic acid substance. After the regeneration treatment of the adsorption material, it can be re adsorbed, and this process is continuously repeated. The process flow of wastewater adsorption treatment is shown in the following figure.

Case Introduction

The newly built adsorption treatment facility for ortho aminobenzoic acid wastewater has a total designed wastewater treatment capacity of 200m 3/d. The wastewater is workshop mother liquor wastewater, which contains a large amount of COD organic matter. The concentration of ortho aminobenzoic acid is high, and conventional biochemical treatment cannot recover ortho aminobenzoic acid. Biochemical treatment is difficult, which brings great pressure to the environmental protection production of the enterprise. Using our company's independently developed special adsorption material for the adsorption treatment of this wastewater, it can efficiently remove ortho aminobenzoic acid substances. Multiple batches of repeated experiments have proven that this method is stable and reliable, ensuring that the effluent continues to meet standards. The wastewater design indicators are shown in the table below.

Figure 3 Recycling of ortho aminobenzoic acid product

The adsorption of ortho aminobenzoic acid wastewater treatment process customized by Haipu can deeply adsorb and remove ortho aminobenzoic acid from wastewater, solving the problem of customer wastewater treatment. At the same time, it can achieve the separation and recovery of ortho aminobenzoic acid, increase the economic benefits of the enterprise, and provide guarantee for stable production on site for customers.

Advantages of adsorption method

1. Deeply removing organic matter from wastewater and reducing the concentration of ortho aminobenzoic acid in the adsorbed effluent can ensure that the effluent meets the discharge standards or operational requirements of subsequent processes;

2. Realize the recycling and utilization of resources, achieve clean and efficient production, and increase the economic benefits of enterprises;

3. Using specially modified adsorption materials, with large adsorption capacity, low equipment investment, and low operating costs;

4. The process flow is simple and can achieve full automation operation, making operation and maintenance convenient;

5. It can achieve multi-layer layout, small footprint, and short installation cycle.
