Wire processing wastewater treatment is an important direction to ensure that the metal products industry develops into a conservation-oriented, low-consumption, high-quality area. So, let’s take a look at the wire processing wastewater treatment methods.

1. Characteristics of wire processing wastewater

1. Wire processing wastewater is wastewater generated during deep processing in the metal products industry. A large amount of wastewater with complex composition can be produced in the production of metal products. There are many types of metal products, such as PC wire, welding wire, spring wire, stainless steel wire, etc.

2. The composition of wastewater generated from different products and production stages is complex. According to the metal product production process, a large amount of process wastewater such as pickling, phosphating, washing, and electroplating will be generated during metal surface treatment.

2. Linear sewage treatment method

1. Due to the large volume and low concentration of sewage, the treatment process mostly adopts the traditional acidic wastewater neutralization and precipitation method, or uses biological methods to precipitate and solidify, landfill heavy metals, and inorganic salts. Sometimes membrane separation processes are also used for purification, concentration, and reuse. .

2. The waste water in wire drawing such as wire drawing lubrication waste liquid is a stable and uniform colloidal substance mixed with oil and water. It mainly includes oil and wire drawing lamp emulsion. This type of waste water has a small drainage volume and is more difficult to treat. In view of the high concentration and difficult treatment of wastewater pollutants produced by removal, the evaporation process is often used to concentrate, refine, crystallize and recycle the waste oil. The higher the concentration, the less steam is consumed for wastewater evaporation.

3. Wire processing wastewater treatment evaporation method

1. The evaporation process is a process that heats the sewage to the evaporation temperature and vaporizes it under normal pressure, positive pressure, or vacuum pressure to achieve concentration and saturation to precipitate inorganic salt crystal grains.

2. Wastewater is treated by evaporation process. Through evaporation, the raw materials are concentrated and crystallized to a certain extent, which can be recycled. This is a relatively common method.

3. The evaporation method for wire processing wastewater treatment generally adopts traditional single-effect, multi-effect evaporation technology and mechanical vapor recompression technology.

4. According to the fluid circulation mode, it can be divided into non-circulation evaporation, natural circulation evaporation, forced circulation evaporation, scraped film evaporation, etc. The correct use of certain technologies can not only improve product quality, but also save energy, reduce production costs, and improve economic benefits.

5. When selecting evaporation technology, it should be determined based on the local steam price, electricity price and investment at that time.
