How about sludge drying and treatment equipment?

● Multi-layer and three-dimensional design, occupying less space and with high efficiency;

● Utilizing solar energy as the main energy source to meet the demand of sustainable development;

● Small energy consumption, low operation and management costs, evaporation of 1t of water consumes only 60-80kW-h, while the traditional thermal drying technology requires 800-1060kW-h of electricity;

● After drying treatment, the volume of sludge can be reduced to 1/3-1/5 of the original volume, achieving stabilization and retaining its original reuse value;

● Stable and safe operation of the system with low dust generation;

● High degree of automation, easy operation and maintenance, and long service life;

● High degree of transparency of the system and good environmental coordination.

Sludge drying and treatment equipment truly realizes the harmlessness, reduction, stabilization and resourcefulness of sludge. It creates a new era of utilizing new energy to treat and dispose sludge in China. It can be widely used for sludge treatment and disposal in various industries such as municipal, chemical, metallurgy, electric power, coal and so on.

Sludge drying treatment equipment involved in sludge treatment projects are:

1. Sludge treatment project of domestic sewage treatment plant (harmless, reduction, stabilization, resourcefulness) will be dewatered sludge drying treatment, sludge grading special treatment: made of high calorific value of dry particles used to make bricks or auxiliary fuel.

2. Sludge treatment project of printing and dyeing sewage treatment plant: printing and dyeing sludge is generally high in inert material, while the content of organic matter, pathogenic bacteria, etc. is low, the calorific value is also low, and the general content of heavy metals is high.

Characteristics of printing and dyeing sludge treatment project: Harmlessness, minimization and resourcefulness.

3. Paper sewage treatment plant sludge treatment works: sludge volume is relatively large, and which contains a large number of fiber content, high water content, generally up to 95% ~ 99%, even after dewatering the water content is still at 0% ~ 80%.

Paper sludge treatment project features: harmless, minimization.

4. Tannery sewage treatment plant sludge treatment works: large amount of mud production, generally can produce 40-80 tons of sludge per day/tons of wastewater, high organic content, due to a large number of hides and skins, blood stains produced in the leather treatment process, so the organic content is very high.

Leather sludge treatment project features: harmless, reduce, resource.

5. Electroplating sewage treatment plant sludge treatment works: containing cyanide and heavy metals such as hexavalent chromium, copper, zinc, cadmium, nickel, etc., chemical treatment of electroplating wastewater is the main source of sludge, electroplating sludge with low organic content and small calorific value.

Electroplating sludge treatment project features: harmless, reduction, stabilization, resource.

6. Petrochemical sewage treatment plant sludge treatment works: the composition is more complex, containing different kinds of heavy metals general oil sludge containing oil, viscosity, water content is high, generally up to 96% ~ 99%, the organic content is small, the calorific value is low.

Characteristics of oil chemical sludge treatment works: harmless, reduction and stabilization.
