The detergent manufacturer takes you to understand how to treat the detergent sewage

Detergent is a cleaning product in daily life, but people often say that long-term use of detergent will be harmful to the body? What ingredients cause it? The detergent manufacturer will introduce the raw materials, production process and sewage treatment process to you. The main materials are AES (fatty alcohol polyoxyethylene ether sulfuric acid) is a typical anionic surfactant, white sticky or clear white. It has the characteristics of good detergency, low irritation, non-toxic, good biodegradability and resistance to hard water. Some manufacturers use calcium dodecylbenzenesulfonate, which is also an anionic surfactant, low cost, buttery, but slightly toxic, poor resistance to hard water, strong degreasing (dry skin, severe peeling, blistering, itching, etc. ). Other materials are sodium sulfonate and fragrance. Mix and stir the raw materials with purified tap water, let stand for 30 minutes, weigh, fill and pack, this is the production process of detergent. In this process, the cleaning of equipment needs to purify tap water, so the waste water mainly comes from here, and some come from cleaning waste water and domestic waste water. Wastewater contains COD, ammonia nitrogen, BOD, SS, LAS and other pollutants, and direct discharge will affect the environment. The detergent factory also needs to treat the wastewater to meet the discharge standards. Basically, the following steps are required. Method 1. Pretreatment method, using the grill and regulating tank to remove large particles of impurities in the water, to ensure the stable execution of subsequent processes. 2. The physical and chemical method uses coagulation sedimentation and air flotation to remove organic matter, toxic and harmful substances, and reduce the burden of subsequent processes. 3. Biological method, using biological contact oxidation method to remove biologically soluble organic matter, remove part of COD, and improve B/C. Finally, according to the actual situation, whether more advanced treatment methods are required to meet environmental standards and emission standards. Detergent is not a natural substance, it is processed and cannot be eaten directly, which will cause harm to the body. Therefore, gloves should be worn when actually cleaning tableware and other items, and the detergent should be cleaned. Manufacturers of detergent also need to scientifically treat production and domestic sewage to avoid environmental hazards to humans.
