LZZG Sludge Treatment Equipment

Sludge treatment equipment has become an indispensable component of modern construction materials. Particularly during peak periods of urban development, the demand for sludge treatment systems is rising year by year. While the role of this equipment in construction projects is becoming increasingly prominent, its production and transportation inevitably generate significant volumes of wastewater.

The sewage sludge treatment equipment designed and developed by LZZG for concrete mixing plants plays a critical role. The primary sources of wastewater generated by concrete mixing operations include runoff from cleaning transport vehicles, site washdown water, and effluent from cleaning the supporting facilities of the mixing tower during production. This wastewater contains not only cement, soil, sand, and other particulate matter but also oil stains, concrete additives, and various chemical ingredients. If this wastewater is not effectively treated and reused, allowing it to discharge naturally into the environment will cause serious pollution.

The sewage treatment system designed by LZZG for concrete batching plants primarily comprises sewage treatment pipelines, oil separation and sedimentation tanks, thickened sludge tanks, sludge separation equipment, sewage pumps, filter presses, and automatic control systems. Wastewater generated during the production process of concrete batching plants contains not only conventional construction materials such as sand and cement but also concrete additives. Direct discharge would result in severe pollution to the natural environment. The sewage treatment plant developed by LZZG is a closed-loop, automated system that adheres to recycling principles: it separates wastewater from mud and sand, decouples mud from water, and discharges solid waste in a dry state. This enables the entire concrete batching plant to achieve environmentally friendly production standards.

Key components of the production line include sewage treatment pipelines, sewage tanks, clean water tanks, sediment separation equipment, fine sand recovery screening systems, thickening tanks, filter presses, and other auxiliary units.

1. Sediment Separation Equipment

A dewatering screen is used to remove moisture from sand and gravel, while a swinging screen classifies these materials for raw material reus

e.

2. Fine Sand Recovery Equipment

Integrated sand washing and recycling machines, or fine sand recovery systems, utilize cyclone separation to wash, dewater, and recover screened materials.

3. Concentration Tank

Mud-water separation is achieved through concentration and sedimentation, producing purified tailwater.

4. Filter Press

Thickened sludge from the concentration tank is pressed into filter cakes using belt filter presses or plate-and-frame filter presses, facilitating sludge dewatering and dry stacking.

LZZG’s sewage sludge treatment systems for concrete batching plants effectively treat and recycle wastewater within the plant area, ensuring zero discharge and supporting clean production goals. These solutions are highly tailored to specific operational needs, with equipment configurations customized according to each customer’s situation.
