Sewage Sludge Treatment Plant

Sewage sludge treatment plant, as an innovative equipment, uses carbonization technology to convert organic matter into charcoal. The machine plays an important role in the environment. The application of the machine can reduce the volume of sewage sludge and solidify harmful substances. In addition, it also incorporates the concept of energy recovery, which provides a new way for sustainable development and resource utilization.


What Raw Materials Can Sludge Treatment Plant Process?

Sewage sludge is a mixture containing solid matter that is separated from wastewater during sewage treatment. It usually contains the following components: organic matter, particulate matter, microorganisms, inorganic salts, heavy metals, and harmful chemicals. The sewage sludge carbonization machine converts the organic matter in the sludge into charcoal through the carbonization process, thereby reducing its volume and harmfulness. The prerequisite for the treatment is that the sewage sludge contains organic matter. The charcoal maker machine can process two kinds of sludge.

Municipal Sludge: Municipal sludge is a by-product produced in the process of urban sewage treatment, mainly from residents’ lives, commercial activities and municipal drainage.

Industrial Sludge: Industrial sludge results from treating wastewater discharged during industrial production, generating solid waste.

Sewage Sludge Treatment and Carbonization Process

Material Pretreatment

Unlike the treatment of other biomass, the treatment of sewage sludge is mainly for reduction. Before entering the machine, some pretreatment steps are usually required, such as solid-liquid separation, sieving, concentration, etc., to reduce moisture content and impurities. In addition to this, it is necessary to use a dryer when the moisture exceeds 15%. This is to improve the final carbonization efficiency.

Carbonization Process

The pretreated sludge is sent to the machine, which operates in a high-temperature and low-oxygen environment. The reaction temperature is usually between 300°C and 600°C. During this process, the organic matter undergoes a carbonization reaction, producing charcoal and some gaseous by-products.

Combustible Gas Recycling

First, the cyclone dust collector dedusts the combustible gas. Subsequently, the purified combustible gas is introduced into the auxiliary furnace as a heat source. The exhaust gas generated after utilization is again subjected to dust removal treatment through the cyclone dust collector. Finally, the exhaust gas is discharged after being purified by the exhaust gas dust collector.

Charcoal Collection

Charcoal is discharged through a three-stage water-cooled discharge machine. It has a lower temperature and doesn’t cause combustion.

Discharge Treatment

At the end of the process flow, further treatment of exhaust gas and wastewater may be required to ensure compliance with environmental regulations and discharge standards.

How to Make Sewage Sludge Charcoal

Traditional Sewage Sludge Treatment VS Sewage Sludge Carbonization Machine

Traditional Sewage Sludge Treatment

Processing Effect: Incomplete

The sludge may still retain organic components, the decomposition is not complete, and other materials may need to be added during the solidification process.

Reuse of Resources: Limited

In traditional treatment methods, the resource recovery and energy utilization of sludge are limited.

Environmental Protection: Inefficient

In the conventional approach to treatment, incineration may produce waste gas, and landfills may cause leakage, which may lead to environmental pollution and health risks.

Technical Requirements and Costs: Complicated

Building and operating urban sewage treatment plants requires a lot of equipment, manpower, and maintenance costs. Processing requires certain technical expertise.

Sewage Sludge Carbonization Machine

Processing Effect: Complete

Carbonization treatment can completely decompose and convert organic matter into solid charcoal, which helps to solidify harmful substances and reduce volume.

Reuse of Resources: Comprehensive

The carbonization process produces charcoal, which finds applications in soil improvement, biomass fuel, and other resource recovery purposes.

Environmental Protection: Sustainable

The carbonization process produces less exhaust gas, and the solids after carbonization are stable, which helps to reduce the release of harmful substances.

Technical Requirements and Costs: Convenient

Purchasing carbonization machines requires a certain amount of investment. The machine is simple to operate and requires proper operation and maintenance.
