At this stage, the total amount of industrial sludge is on the rise. If it is discharged without treatment, it will cause great harm. So, how do you know how to treat industrial sludge? There are also many methods for sludge treatment. The following is a detailed description of the industrial sludge treatment method and provides you with an ideal solution for industrial sludge treatment.

First, how to deal with industrial sludge?

1. Drying heat treatment

The so-called drying heat treatment is to use the drying equipment to treat the sludge and make progressive use of the sludge. This method will reduce the volume of the sludge and make the sludge more stable, eliminating the odor of the sludge and Pathogenic organisms. The sludge after drying can be used as both a soil improver and an energy source. At present, the technology has gradually matured and is used by some developed homes.

2. Incineration treatment

Incineration is a traditional way of treating sludge in sewage treatment plants. By incineration, organic matter and pathogens in the sludge can be eliminated, and the volume of sludge can be reduced to a large extent. However, this treatment requires processing with expensive equipment, a large amount of treatment, and harmful gases are generated during the incineration process, and the sewage treatment plant must be progressively treated to treat these harmful gases.

3. Landfill treatment

Compared with other sludge disposal methods, landfill treatment is a relatively simple treatment method, and the cost of landfill is less. This method is a relatively mature sludge treatment method. However, landfill sludge treatment is poor and limited by land resources. At the same time, landfill sludge may affect local groundwater, etc., and pollute the groundwater. In order to avoid this problem, the sewage treatment plant must reduce, stabilize and harm the sludge. In order to ensure that it will not pollute the soil and groundwater, maintain a good ecological environment.

4. For agriculture

As far as the sludge itself is concerned, it contains some organic matter that can be converted into nutrients needed by the soil. For this reason, the sewage treatment plant can use the organic matter in the sludge for agriculture, which becomes a way of treating sludge. In this way, the fertilizer of the sludge can be used in forest land, vegetable fields and fields, and the pollution caused by the sludge is reduced, and it becomes a relatively green treatment.

Through the introduction of the above sludge treatment method, we can find that if it is for a large amount of industrial sludge, the practical method for reducing environmental pollution is to carry out dry heat treatment, which requires the use of a professional treatment equipment is a sludge dryer.

Second, the advantage of sludge dryer treatment sludge

Industrial sludge heat pump dryer can fully realize the utilization of municipal sludge reduction, stabilization, harmlessness and resource utilization. The final sludge particles can be turned into fertilizers, fuels, incineration, building materials, landfills, biofuels, etc.

The sludge dryer drying system is highly adaptable and can even be used for materials that are difficult to handle. The entire drying system is easy to control. It can be applied to a variety of fuels, such as various natural gas and petroleum. Throughout the drying process, the operator can observe the burning rate through a temperature instrument in the dryer discharge tube. The sludge dryer drying system can use a variety of fuels, such as electricity, oil, natural gas and the like. The hot air of the drying system can be secondary or secondary indirect hot air. The sludge dryer has a good dry fruit, which reduces the investment cost. No secondary pollution, good safety performance and low investment. After the drying process, the sludge can be reused as a useful secondary resource.

The sludge dryer has a wide range of drying and is available for customers to choose from. Drying capacity can range from 100kg/h to tens of tons per hour. The equipment has a reasonable structure and a small footprint. Lower energy consumption and lower operating costs. The system has a higher heat rate due to the air exchanger and the waste heat boiler. Compared with traditional drying systems, sludge dryer energy consumption can be reduced by 20%-30%. The dried fruit is remarkable.

The entire drying system is environmentally friendly. With a complete exhaust gas treatment system, rotary dust removal system and bag filter, it emits almost no dust to the air. The acid-base neutralization process and the dust precipitation process are carried out simultaneously, and the odor can be completely eliminated. Therefore, the exhaust gas can reach the emission standard.
