Plastic cleaning sewage treatment equipment case

Plastic cleaning sewage treatment case introduction:

The wastewater generated by different raw materials is very different, the difference is large, the biodegradability is low, the suspended solids in the wastewater generated in the cleaning and crushing process are high, and most of the wastewater after physical and chemical treatment enters the process for reuse, and a small part is The domestic sewage enters the biochemical system for treatment and discharges up to the standard.

The project is a plastic cleaning, crushing and granulation project in Malaysia, with an annual output of 200,000 tons.

1. Sewage treatment capacity of the first phase project: 200 cubic meters per day.

2. Processing technology:

①. Sewage treatment process: mechanical grid - high-efficiency micro drum filter machine - air flotation and sedimentation integrated machine - water reuse

②.sludge treatment process: dosing device - screw press sludge dewatering machine

3. Process introduction:

A. Mechanical grille: The mechanical grille can remove garbage and large particles of impurities to ensure that the water pump will not be blocked behind

B. High-efficiency micro drum filter machine: The micro drum filter machine can remove small particles of impurities and ensure that the air flotation machine will not be blocked in the future.

C. Air flotation and sedimentation integrated machine: Through dosing and flocculation, the air flotation machine can remove 95% of the suspended solids. The treated water is very clear and can be recycled and used to continue cleaning plastics.

D. The sludge from the micro drum filter machine and the air flotation machine is processed by the screw dehydrator, and the mud cake can be transported out for processing
