Aluminum Profile Surface Treatment Wastewater Treatment and Repurchase Technology

Aluminum profile surface treatment wastewater treatment and reuse technology

The best concrete, aid agent, and its investment were determined by the concrete precipitation test, and the impact of the microfiltration operation factors on the film filtration performance and the overall operation effect of the combined process, and conducted technical and economic analysis. Top ten brands of aluminum and products made by other alloy elements. It is usually made into a casting product, forging products, as well as foil, board, band, tube, stick, profile, etc., and then made by cold bending, sawing, drilling, assembly, coloring and other processes. The main metal elements are aluminum, which adds some alloy elements to improve the performance of aluminum. The two-sided aluminum plate of the whole aluminum home, and the PVC plate core filled in the middle of the PVC board is usually about 1.4-1.8 density values (the smaller the density value, the better the quality). The material of the doors and windows and doors and windows is connected to the wall. The main feature is that the surface of the wall is mostly plane, and it cannot be moved on the wall. This combination process can save water, reduce pollution, and have multiple benefits of social, environmental and economy.

1. Test materials and methods

1.1 Test water

The testing equipment is directly placed in the production line of the production line of the integrated drainage flow adjustment slot, the aluminum surface treatment of the aluminum plant on the production line of the integrated drainage flow (containing other plants other pollutant chromium wastewater, and the nickel into the process of the adjustment tank. Tibet), the wastewater is adjusted directly from integrated drainage flow, water quality: 500600mg/L of AL3, SO42-20003000mg/L, turbidity 300500NTU, pH35.

1.2 Test device

Aluminum profile surface treatment wastewater treatment and reuse technology

The condensation box, the effective volume precipitation and filter tank are 30,50,80L, which is 0.27 mm inner diameter of Mitsubishi, 0.1m, the diameter of the membrane fiber membrane, 0.42 mm outer diameter, and the film area of 2.0 square meters. Fiber membrane. The membrane filter is placed directly in the swimming pool, which is set under the air exposure of the air, and the action is refined. The outlet tube of the solenoid valve is at both ends of the membrane component, and the aeration time is at the water controller system.

1.3 Test method

1.3.1 Curgee to screen technical test

In order to choose the appropriate concrete and aid agent, in the exploration stage, the sequential test was used in batches, and the concrete effects of various commonly used concrete were compared. According to the characteristics of the surface treatment of the wastewater on the surface of the aluminum profile and the needs of the subsequent wastewater treatment scheme, the turbidity, AL3, SO42-removal rate, and the sedimentation of flocculantal agents are selected as indicators.

Take 1000ml of cup, add 500ml wastewater temperature and room temperature of 28 C, add the concrete, add NaOH powder to regulate the pH value to 8.0, then add the aid agent PAM, add 360R/min and 150R/min of 360R/min and 150R/min, respectively. , Stir for 1min for 1min, stir for 2min, 30min, determine its flocculation and precipitation effect.

1.3.2 Membrane filtrationconcrete test composition

The concrete and aid agent solution can be studied separately through the analysis of the water absorption pipeline of the pump through the analysis of the measurement valve, and it is continuously mixed with the raw water through the improvement of the impeller. The upper liquid after the mud is separated into the filter pool, and the pump pumping therapy under the effect of suction pump and suction treatment under the action of the meterum filtering technology obtains information filtering to treat the water. The intake valve and the water outlet valve alternately teaching work under the control of the time management controller. According to the content of suspension in the water out of the concrete system, every 68 cycles cannot exclude the bottom mud at the bottom of the safe filter.

2. Results and discussions

2.1 Settlement Settlement Test

In order to increase the degree of compressed flocculation PAM, it is used as FECL2, trichlorite, FE2 (SO4) 3, aluminum aluminum, calcium (OH) 25 kinds of coagulants for the research.
