stay Printing and dyeing wastewater treatment In the process, Horizontal screw centrifuge It is a commonly used equipment, mainly used to separate suspended solids and sludge in sewage. Printing and dyeing wastewater It usually contains a large amount of organic matter, suspended solids and sludge, and these pollutants need to pass through the snails Centrifuge Separation and removal shall be carried out to meet the discharge standard of sewage treatment plant.
The application of horizontal spiral centrifuge in printing and dyeing wastewater treatment is mainly reflected in the following aspects
1. Sludge dewatering: sludge particles are flocculated by adding flocculants, and sludge dewatering is achieved by using the centrifugal force of horizontal spiral centrifuge, so as to improve the solid content of sludge and reduce the water content of sludge.
2. Suspended solids separation: suspended solids in printing and dyeing wastewater, such as fiber, dye particles, etc., can be separated by horizontal spiral centrifuge. By adjusting the parameters of horizontal screw centrifuge, suspended solids in sewage can be effectively removed.
3. Environmental protection: effectively treat suspended solids and sludge in printing and dyeing wastewater, reduce environmental pollution, and comply with relevant national regulations on environmental protection.
4. Cost saving: the application of horizontal spiral centrifuge in printing and dyeing wastewater treatment can reduce Sludge treatment And disposal costs to save operating costs.
When selecting horizontal spiral centrifuge, it is necessary to consider the specific characteristics of printing and dyeing wastewater (such as sludge concentration, sludge particle size distribution, sludge viscosity) and treatment requirements (such as treatment capacity, sludge recovery rate, sludge solids content, etc.) to determine the appropriate model and parameters. At the same time, the operation cost, maintenance convenience and compliance with local environmental protection regulations of the equipment shall also be considered.
In a word, the decanter centrifuge plays an important role in the treatment of printing and dyeing wastewater, helping to improve the efficiency of wastewater treatment and reduce the cost of treatment, as well as promoting the green development and environmental protection of the printing and dyeing industry.
