Industrial Wastewater Disposal

Brief Introduction

Industrial wastewater, including production wastewater and polluted industrial wastewater, refers to wastewater and waste liquid generated in the process of industrial production, including materials for industrial production, intermediate products, by-products and pollutants generated in the production process that are all lost with water.

Case presentation - 10,000 m³ high-salt organic wastewater project, which is full of challenges. Our company uses algae nutrient source to treat it to meet the urban sewage discharge standard and directly discharges it into the receiving pipe. A science and technology limited company located in Shandong produced 10,000 m³ of high-salt wastewater in the operation and production process; the COD of the salt is up to 70,000 mg/L, the ammonia nitrogen is up to 2,000 mg/L, and the total salt content is more than 300,000 mg/L

Disposal method

1. The non-toxic production process is preferred to replace or reform the backward production process to eliminate or reduce the generation of toxic and harmful wastewater in the production process as much as possible.

2. In the process of using toxic raw materials and producing toxic intermediates and products, strict operation and supervision should be carried out to eliminate dribbling, reduce loss, and reasonable processes and equipment should be adopted as far as possible.

3. Wastewater containing highly toxic substances, such as some heavy metals, radioactive substances, high concentration phenol and cyanide wastewater, should be separated from other wastewater to facilitate the treatment and recovery of useful substances.

4. Wastewater with large flow and light pollution should be treated properly and recycled, and should not be discharged into sewers to avoid increasing the load of urban sewers and urban sewage treatment.

5. Organic wastewater similar to urban sewage, such as food processing wastewater, sugar manufacturing wastewater and papermaking wastewater, can be discharged into the urban sewage system for treatment.

6. Some toxic wastewater that can be biodegraded, such as phenol and cyanide wastewater, should be treated first, and then discharged into the urban sewer according to the allowable discharge standard, and then further biochemical treatment.

7. Toxic wastewater that is difficult to be biodegraded should be treated separately and should not be discharged into urban sewers. The development trend of industrial wastewater treatment is to recycle wastewater and pollutants as useful resources or implement closed-circuit circulation.
