Printing and dyeing sewage treatment equipment is an indispensable environmental protection equipment in the printing and dyeing industry, which can effectively treat the sewage generated by the printing and dyeing industry, and play an important role in protecting the environment and saving resources.
This article will make an in-depth analysis of the printing and dyeing sewage treatment series equipment, and derive some other related content to make it more abundant.
1. Classification of printing and dyeing sewage treatment equipmentPrinting and dyeing sewage treatment equipment is mainly divided into three categories: physical treatment, chemical treatment and biological treatment.
Physical treatment mainly uses filtration, precipitation and other methods to remove suspended solids and color substances;
Chemical treatment is the removal of organic and inorganic substances by adding chemicals;
Biological treatment uses the action of microorganisms to degrade organic matter into inorganic matter to achieve the purpose of purifying water quality.
2. Physical processing equipment 1Filter: Printing and dyeing sewage often contains a large amount of suspended solids, and the filter screen can effectively filter out large solid particles;
2.Sedimentation tank: by slowing down the flow rate of sewage, the suspended solids can be precipitated to achieve the purpose of purifying water quality;
3.Air flotation machine: By introducing gas into the sewage, bubbles are formed, and the suspended solids are brought to the surface of the water through the action of bubble rising, and then removed.
3. Chemical treatment equipment 1Coagulant dosing system: the coagulant is evenly added to the sewage, so that the suspended solids in the sewage are condensed into larger particles, which is convenient for subsequent treatment;
2.Pharmaceutical dosing system: according to the specific components in the sewage, the corresponding chemicals are added for reaction to achieve the purpose of removing organic and inorganic substances;
3.Neutralizer dosing system: After the treatment of the agent, the neutralizer is added to neutralize the agent to prevent the impact on the subsequent treatment.
Fourth, biological treatment equipment 1Activated sludge method: the activated sludge containing microorganisms is put into the sewage, and the microorganisms purify the sewage by phagocytosing organic matter;
2.Anaerobic sludge method: under anoxic conditions, anaerobic microorganisms are put into sewage, and organic matter is decomposed into inorganic substances such as methane through the action of microorganisms;
3.Through-flow aeration tank: Inject air into the sewage through the aeration device to increase the supply of oxygen, provide an ideal growth environment, and promote the growth and reproduction of microorganisms.
Through the combination of physical treatment, chemical treatment and biological treatment, the printing and dyeing sewage treatment series equipment can efficiently treat the sewage generated by the printing and dyeing industry.
These equipment provides reliable environmental protection solutions for printing and dyeing enterprises, protects the environment, enhances the corporate image, and is a necessary equipment for the development of the printing and dyeing industry.
In the future, with the continuous improvement of environmental protection requirements, the printing and dyeing sewage treatment series equipment will continue to innovate and inject more vitality into the development of the industry.
