Treatment of Chemical Industrial Wastewater

1. Characteristics:

(1) The composition of water quality is complex with numerous by-products. The reaction raw materials are often solvent substances or compounds with cyclic structures, which increases the difficulty in treating wastewater.

(2) The content of pollutants in wastewater is high.

(3) There are many toxic and harmful substances.

(4) There are many substances that are difficult for biological degradation. The ratio of B to C is low and the biodegradability is poor.

(5) The chroma of wastewater is high.

2. Treatment Difficulties:

The composition of water quality is complex, the water quality is unbalanced, the concentration of organic substances is high, and the toxicity is great.

3. Treatment Process:

Physicochemical treatment + biochemical treatment

4. Solutions:

After applying multi-stage physicochemical treatment methods for pretreatment to improve the biodegradability of the wastewater, the combined anaerobic + aerobic treatment process is then applied to remove pollutants in the wastewater so that it can be discharged up to the standards.

5. Discharge Standards:

The first-class discharge standard for the second period specified in the Integrated Wastewater Discharge Standard (GB8978-1996).

The first-class discharge standard for the second period specified in the Discharge Limits of Water Pollutants in Guangdong Province (DB44/26-2001).
