The circulating water of fully automatic buried sewage equipment will affect the equipment

Now the environmental pollution around us is getting worse and worse, and all kinds of domestic sewage are discharged at will. The emergence of fully automatic underground sewage treatment equipment has brought good news to sewage treatment, solved the problem of domestic sewage, and integrated sewage treatment The equipment occupies a small area and is easy to operate. It is suitable for sewage treatment in various places. Today, let's learn about the impact of the circulating water of the fully automatic buried sewage treatment equipment on the equipment.

1. Corrosion: The corrosion of circulating water on heat exchange equipment is mainly electrochemical corrosion. The causes include equipment manufacturing defects, sufficient oxygen in water, corrosive ions in water, and dirt generated by mucus secreted by microorganisms. The consequences of corrosion It is very serious, even if the heat exchanger and water pipeline equipment are scrapped in a very short time without control.

2. Dirt: Dirt is mainly composed of organic matter in water, microbial colonies and secretions, sediment, dust, etc. The texture of the dirt is soft, which not only reduces the heat transfer efficiency but also causes corrosion under the scale and shortens the service life of the equipment.

3. Scale: Due to the continuous evaporation of circulating water during the cooling process, the salt concentration in the water increases continuously, exceeding the solubility of some salts and depositing. The common ones are calcium carbonate, calcium phosphate, magnesium silicate and other scales. The texture of scale is relatively dense, which greatly reduces the heat transfer efficiency. A scale thickness of 0.6 mm reduces the heat transfer coefficient by 20%.

4. Microbial slime: Because there are sufficient oxygen, suitable temperature and eutrophic conditions dissolved in circulating water, it is very suitable for the growth and reproduction of microorganisms. If it is not controlled in time, it will quickly lead to deterioration of water quality, odor and blackening, and a large amount of slime in cooling towers. Scale deposits or even blockage, the cooling and heat dissipation effect is greatly reduced, and the corrosion of equipment is intensified.
