Sewage Sludge Carbonization Plant

Sewage sludge carbonization plant plays a vital role in managing the by-products of the sewage treatment process. Sewage sludge’s correct handling is essential to reduce pollution, improve resource utilization and promote sustainable development. Beston sewage sludge treatment plant is equipped with advanced pyrolysis technology. The machine realizes efficient conversion of sewage sludge into biochar. This recycling model of turning waste into treasure is being strongly promoted by recyclers.

Classification of Sewage Sludge

In the modern sewage treatment process, sludge is an inevitable by-product. According to the source of sewage, sewage sludge can be divided into municipal sewage sludge and industrial sewage sludge.

Municipal Sewage Sludge

Municipal Sewage Sludge

Municipal sewage sludge mainly comes from urban sewage treatment plants, and the treatment objects include domestic sewage and sewage from some commercial and public facilities. Its composition is as follows:

  • Organic Matter: including various biomass, such as animal and plant excrement, food residues, paper scraps and other microorganisms..
  • Inorganic Matter: including sand, metal oxides and other inorganic particles.
  • Nutrient Elements: including trace elements such as nitrogen, phosphorus and potassium.

Industrial Sewage Sludge

Industrial Sewage Sludge

Industrial sewage sludge comes from the wastewater treatment system in the industrial production process, mainly from papermaking, food processing, printing & dyeing and other industries. Its composition is as follows:

  • Organic matter: mainly comes from raw materials, auxiliary materials and their decomposition products in industrial production.
  • Inorganic matter: including process additives, catalyst residues and other inorganic wastes.
  • Heavy metals: such as compounds containing lead, mercury, cadmium and chromium.

What is Sewage Sludge Carbonizing Plant?

Sewage sludge carbonizing plant is a charcoal equipment designed to convert sewage sludge into biochar through a carbonization process. This process involves heating the sludge at high temperatures in an oxygen-free environment. It leads to the decomposition of organic matter and the production of biochar, a carbon-rich material. This sludge treatment plant typically consists of several key components, including feed system, carbonization reactor, gas treatment system and biochar collection system.

How to Convert Sewage Sludge into Biochar

Both the reduction treatment and resource utilization of sewage sludge are crucial. As an advanced solution, the sewage sludge carbonization plant converts sewage sludge into biochar through a high-temperature carbonization process. This not only reduces the sludge volume and treatment costs, but also recycles the useful components in biochar. This achieves the dual goals of environmental protection and resource recovery. Below you will learn about the working principle of the biochar machine:

Drying of Sewage Sludge

The dryer reduces the water content of sewage sludge to 15%.

01

Carbonization of Sewage sludge

After preheating for about 90 minutes, the sewage sludge enters the sludge treatment system. In the high-temperature micro-oxygen environment, the organic volatiles inside the biomass are continuously released. Finally, carbon-rich residues, biochar, are formed.

02

Sewage Sludge Biochar Collection

After the carbonization reaction is completed, the biochar passes through the discharge system. The system consists of three water-cooled screw dischargers to achieve the cooling and collection of biochar.

03

Combustible Gas Reuse

The combustible gas generated by the sewage sludge carbonization is first subjected to dust removal and condensation treatment. Subsequently, the purified combustible gas re-enters the combustion system through the pipeline. It provides a heat source for the operation of the sewage sludge carbonization plant.

04

Waste Gas Treatment

The waste gas generated by the entire reaction will pass through the dust removal tower and spray tower for dust removal and cooling. Finally, the waste gas is discharged from the chimney.

Comprehensive Advantages of Sewage Sludge Carbonization Machine

Sewage Sludge Reduction

Reduction

  • Beston sludge treatment equipment converts most of the sludge into biochar and gas through oxygen-free high-temperature treatment. This significantly reduces the amount of sludge after treatment.
  • The carbonization process not only reduces the volume and weight of sewage sludge, but also releases gas while degrading organic matter. This achieves the dual benefits of waste reduction and energy recovery.
  • Sustainable sludge reduction reduces landfill or incineration treatment. Therefore, this reduces the occupation pressure on landfills and greenhouse gas emissions.
01
Sewage Sludge Resource

Resource Utilization

  • The carbonization plant integrates nutrients such as phosphorus in the sludge into biochar. At the same time, biochar itself has a good pore structure and a large surface area, which is conducive to soil water and fertilizer retention, improving soil aeration and water use efficiency. These advantages, combined with nutrients such as phosphorus rich in biochar, can significantly improve soil fertility and promote crop growth.
  • Biochar can also be used as an alternative fuel for power generation or heating purposes. The heat energy generated by burning biochar can effectively utilize the organic matter in sewage sludge, while reducing dependence on traditional energy and promoting the use of renewable energy.
02
Sewage Sludge Harmless

Harmless

  • Pathogens and microorganisms may exist in sewage sludge, posing a threat to public health. The high temperature conditions of the carbonization process can effectively kill these pathogens and microorganisms. This makes sewage sludge biochar a safe and usable resource.
  • Organic pollutants such as drug residues, organofluorine compounds, hormone disrupting molecules, etc. are common in sewage sludge. Sewage sludge carbonization machine can completely degrade or separate these organic pollutants. This ensures the quality and safety of biochar.
