Titanium Dioxide Wastewater

A large amount of waste acid is produced in the production of titanium dioxide, a large amount of high-salt wastewater is generated in the post-treatment process, and some titanium dioxide is still lost after the CN filter. On the one hand, the titanium white industry suffers from increasingly strict Environmental constraints, on the other hand, waste acid, water, and titanium dioxide resources are huge. Therefore, titanium dioxide water treatment has received an increasing attention. JIUWU has developed a series of membrane treatment technologies for waste acid treatment, titanium dioxide recovery, and water reuse.

Technical introduction

The membrane process is based on membrane separation technology. The salt and acid in the waste acid, the salt, and water in the waste brine are separated to achieve the acid and salt in the waste acid, and the salt and water in the brine can be reused. The removal rate of the metal salt in waste acid is over 98%, the recovery of titanium dioxide is 99.99%, and the water production index reaches the international first-class standard. The separation membrane is a cross-flow filtration method, which greatly reduces membrane fouling, delays the rate of membrane fouling, and improves ceramic membrane filtration efficiency.

Process

Titanium dioxide production includes two production methods, sulfuric acid, and chlorination. For two different production methods, JIUWU has designed different membrane processes.


1. Titanium white waste acid treatment process for sulfuric acid method

titanium dioxide wastewater


2. Titanium dioxide second washing water treatment process for sulfuric acid method

Characteristics of Pocket Hearing Amplifier

Box hearing aids are also called body-mounted or pocket hearing amplifier. The shape of the box is like a small radio. The microphone, amplifier and battery of the hearing aid are assembled in the box and a long wire connects the earphone to the earplug or a special ear mould. Usually in pockets or special pouches. This kind of hearing aid has a large volume and is suitable for the elderly and people with inconvenient finger movement. The microphone of the hearing aid is far away from the receiver (earphone), so it is not easy to produce sound feedback. Therefore, the maximum output limit of the hearing aid is small, the power can be very large, and multiple manual adjustment knobs can be placed. Its price is low, maintenance is convenient, use No. 5 or No. 7 batteries, can also use rechargeable batteries.

Pocket hearing amplifier can also be made into binaural hearing aids because of their large size and poor concealment. Hearing aids are made of ordinary transistor elements, which have high background noise. In addition, the pocket hearing amplifier themselves and the friction between wires and clothes make the sound more distorted and the quality of the sound reduced. At the same time, earphone wires are easy to damage and children are not safe to wear.

Lifep04 lithium battery (lifep04) cathode material is considered as one of the most promising cathode materials for lithium ion batteries because of its excellent electrochemical properties.  However, its development has been restricted by its low conductivity and slow diffusion rate of lithium ions. In this paper, the effects of ion doping, carbon coating and nano-materials modification on lithium iron phosphate cathode materials for lithium ion batteries and the existing problems are mainly introduced, and the development trend and key research directions of LiFeP04 lithium battery are prospected.

Because the lithium iron phosphate cathode material has poor conductivity and low lithium ion diffusion coefficient, researchers at home and abroad have done a lot of research in these areas, and achieved some good results. Its modification research mainly includes three aspects: doping method, coating method and nano-materials.

Lithium-ion batteries are widely used in mobile phones, notebook computers, digital cameras, electric vehicles, aerospace, military equipment and other fields because of their high energy density, low self-discharge current, high safety, high current charge-discharge, many cycles and long life.

Portable Magnetic Flux Leakage Testing Equipment

Magnetic flux leakage test refers to the formation of a leakage magnetic field on the surface of a test piece after it is magnetized due to defects on the surface or near-surface of the test piece. People can detect defects by detecting changes in the leakage magnetic field.

 

Briefly describe the magnetization of ferromagnetic components. In the magnetic non-destructive testing, magnetization is the first step to realize the detection, which determines whether the leakage magnetic field signal can be generated, and also affects the performance characteristics of the detection signal and the structural characteristics of the ndt machine. Like magnetic particle inspection, magnetization is achieved by a magnetizer, including both a magnetic source and a magnetic circuit. The magnetic source and the magnetic circuit change depending on the structure of the member to be tested.

 

What kind of magnetization can be divided into several categories? The magnetization methods can be generally divided into five categories, namely, alternating current magnetization mode, direct current magnetization mode, permanent magnet magnetization mode, composite magnetization mode, and integrated magnetization method.

 

What are the characteristics of magnetic flux leakage detection technology?

 

Because leakage magnetic field detection uses magnetic sensors to detect defects, compared with magnetic powder, penetration and other methods, it has the following advantages:

  1. It is easy to realize automation. The computer judges the presence or absence of defects based on the detected signals.
  2. The fundamentally high detection reliability can solve the influence of human factors in the magnetic powder and osmosis method, and has high detection reliability.
  3. can achieve preliminary quantification of defects.  In the range of wall thicknesses up to 30 mm, the inner and outer wall defects can be detected simultaneously.  In the detection of the pipeline, 5 high-efficiency, pollution-free automated inspection can achieve high detection efficiency.

Polysilicon Cutting Fluid Recovery

In recent years, the wafer industry has developed rapidly, but at the same time, it also produces a large amount of wastewater. The production wastewater mainly comes from the cleaning process of the polysilicon ingot slicing process. The acid-containing wastewater is produced in the cleaning process after the surface treatment of the polycrystalline silicon ingot with the mixed acid. Since the surface treatment is a mixed acid of nitric acid + hydrofluoric acid, the main pollution in the washing wastewater is pH, fluoride, and nitrate. The organic wastewater is produced in the cleaning process of the sliced polycrystalline silicon wafer. Since the cutting fluid (the main component is polyethylene glycol) and the cut micro powder (the main component is silicon carbide) are used for slicing, the main pollutant in the cleaning wastewater is CODCr and SS.

Polysilicon cutting fluid is made up of polyethylene glycol as the main body and added with various additives. It has a suitable viscosity index, good fluidity, and thermal conductivity, and has good dispersion stability and suspension effect on silicon carbide micropowder. A large amount of waste liquid is generated after cutting, and the waste liquid contains a considerable amount of polycrystalline silicon powder, which has a certain recovery value. The polysilicon powder is recovered by the ceramic membrane separation technology, becoming the so-called cutting fluid recovery. And the site is clean and sanitary, which is in line with the national energy-saving and emission-reduction industry orientation.

Ceramic membrane equipment technology is advanced and mature, with low operating costs and fast return on investment.
