Overview

Pure water machine and equipment maintenance, equipment principle: Anodizing wastewater is difficult to treat due to the presence of pollutants such as nickel, phosphorus, oil, and heavy metals, and is subject to strict discharge standards (such as total nickel ≤ 0.1mg/L). The processing equipment needs to combine physical and biochemical processes to achieve quality pre-treatment, deep purification, and resource reuse.

Core process and equipment composition

1. Quality pre-processing unit

-Nickel containing wastewater treatment:

-Equipment: Homogenization tank (corrosion-resistant steel mixing)+Fiberglass lined concrete pool（pHcontroller+NaOHDosing system, flocculation tank（PAMDosing), nickel precipitation tank.

-Function: Through chemical precipitation（pH 9~10）Generate nickel hydroxide sludge to ensure nickel meets the standard (≤)0.05 mg/L）.

-oily/Acid alkali wastewater treatment:

-Equipment: oil separation tank (density separation), regulating tank (water quality balance).

-Function: Remove floating oil and suspended solids, and reduce subsequent loads.

-Phosphorus containing wastewater treatment:

-Equipment: Dedicated coagulation tank (adding calcium salt or aluminum salt)+Design a sedimentation tank based on the characteristics of chemical polishing wastewater.

2. Deep processing and reuse unit

-Membrane separation system:

-Ultrafiltration（UF）：PPMaterial: Hollow fiber membrane（0.1 MmPrecision), removing colloids and emulsified oil.

-Reverse osmosis（RO）: Two levelsROSystem (such as8040Type membrane module), desalination rate>95%, achieve70%Reclaimed water (conductivity ≤)30 MS/cm）.

-Biochemical treatment:

-Biological Contact Oxidation Tank: Push Flow Design+Elastic three-dimensional filler, resistant to impact loads,CODHigh removal rate and low sludge production（90Tianpai Mud1Next time).

3. End of pipe guarantee and sludge treatment

-air flotation+Sand filtration: Remove residual suspended solids to ensure compliance with emission standards.

-Sludge dewatering: Plate and frame filter press (moisture content of sludge cake)<60%）Or centrifuge, nickel containing sludge classified as hazardous waste（HW32）Disposal.
