[Report] Wu Hanyang: Application of hollow plate ceramic membrane and ceramic filter element in the field of environmental protection
Nowadays, the use of porous ceramic technology to carry out in-depth treatment of water and gas to improve the degree of cleanliness has become a fairly mainstream method.
In the field of water treatment, whether it is the treatment of urban sewage or industrial wastewater, or the purification of groundwater such as well water into domestic water or drinking water, ceramic membranes are widely used in various environmental projects by virtue of their excellent adsorption and environmental compatibility. A good application effect has been obtained. Ceramic membranes are mainly divided into three types: plate type, tubular type and multi-channel type. Among them, the hollow plate type ceramic membrane ranks first in the application of ceramic membranes due to its large filtration area, good chemical stability, acid and alkali resistance, and strong anti-microbial ability.
The application of flat ceramic membrane group in sewage treatment project
Hollow plate ceramic membrane is mainly based on the theory of "physical sieving", according to within a certain range of membrane pore size, the permeability of the permeable material is different with different molecular diameters, so as to achieve the nanofiltration effect. The transmission performance of ceramic membranes is closely related to its microstructure, such as pore size and distribution, pore morphology, porosity and connectivity, etc. After testing, flat ceramic membranes have a pore size of 0.05-1um. Virus filtration can reach more than 99%. At present, the application of hollow plate ceramic membrane modules in MBR (Membrane Bioreactor) has been highly valued in the field of environmental protection. Compared with many traditional biological water treatment processes, the plate ceramic membrane MBR treatment system occupies more than 50% of the area. , only a small amount of excess sludge is produced, the effluent quality can reach the standard of reclaimed water reuse, and the process operation is simplified and the reliability is high.

In the building materials, metallurgy, chemical and other industries, the high-temperature flue gas and dust emitted by production will also cause serious pollution to the environment. In order to reduce the emission of harmful dust, porous ceramic filter material has become one of the main means of purifying high-temperature flue gas. It can pass through inertial collision, interception, diffusion, screening, electrostatic effect, electrostatic effect, etc. Various mechanisms such as gravitational settling and adhesion effects filter high-temperature dust-laden gases. However, with the increasingly strict environmental protection requirements, the traditional process cannot meet the new environmental protection emission requirements. Therefore, the high-temperature dust-nitrogen integrated honeycomb ceramic membrane filter element tailored for high-temperature dust-laden gas came into being. With its ultra-high filtration area, Excellent thermal shock resistance, ultra-thin filtration path, and high temperature dust and nitrate integrated honeycomb ceramic membrane filter element are obviously more handy in high temperature flue gas dust removal.
High temperature dust and nitrate integrated honeycomb ceramic membrane filter element
Whether it is a hollow plate ceramic membrane or a high temperature dust and nitrate integrated honeycomb ceramic membrane filter element, both of them are actually the flagship products of Jiangxi Boxin Jingtao Environmental Protection Technology Co., Ltd. As a fine ceramics enterprise rooted in the field of environmental protection for nearly 20 years, Jiangxi Boxin has deep experience in industrial organic waste gas treatment, domestic sewage treatment, industrial wastewater treatment, and oily wastewater treatment.
If you want to have an in-depth exchange with Jiangxi Boxin on the application of porous ceramics in the field of environmental protection, there is a good opportunity now. At the "2019 'Industrial Ceramics City' Innovation and Development Forum" held on June 17-19, general manager Wu Hanyang, the founder of Jiangxi Boxin, will bring us a presentation entitled "Hollow plate ceramic membrane and ceramic filter element in the Applications in the Environmental Protection Field" report. In addition to discussing the structure, performance and application problems of the hollow plate ceramic membrane and the problems to be solved in the future, the high temperature dust and nitrate integrated honeycomb ceramic membrane filter element and its application are also the focus of the report. do not miss it!
Time flies, the years change, and time has gone through another spring, summer, autumn and winter. The year of the ox has passed away, and the year of the tiger follows one after another. The year of 2022, which is full of expectations, is coming to us. In the new year, new flowers will bloom along the way, and new fruits will bear along the way. On January 24, 2022, all employees of the company gathered together to hold the 2021 annual summary and commendation meeting to summarize the achievements and shortcomings of the past year, look forward to the future, and determine the development direction and goals for the coming year.
On July 19, the Ministry of Industry and Information Technology of the People's Republic of China announced the list of the third batch of specialized, special and new "little giant" enterprises. With its outstanding performance in innovation ability, brand influence, economic benefits, management and other aspects, Boxin Environmental Protection was successfully selected as the third batch of national specialized, special and new "little giant" enterprises. It marks that the company has been recognized and affirmed by the state and the Ministry of Industry and Information Technology in many aspects such as advanced core technology, business expansion scale and development quality demonstration.
In December 2021, our company ushered in another major good news. Boxin's "BoCent" brand-"Honeycomb Ceramic Heat Storage Body" product won the honorary title of "Ganchu Excellent" awarded by the Jiangxi Provincial Government. This is the government and all sectors of society. Boxin has affirmed the pursuit of perfection in product excellence and quality over the years.
Green Development 2021 National Chemical Organic Waste Gas (VOCs) Comprehensive Treatment Forum was successfully held in Xi'an on May 19, 2021, and ended successfully on May 21, 2021! Boxin Environmental Protection was invited to attend the conference and gave a report on "Honeycomb Stereoscopic Ceramic Membrane and Its Application in High Temperature Gas". The conference was jointly sponsored by the Chemical Committee of China Industrial Environmental Protection Association and Xi'an Yuchang Environmental Technology Co., Ltd., with leading experts from the Ministry of Ecology and Environment, relevant domestic research institutions, and institutes, as well as fine chemicals, pharmaceutical chemicals, pesticide chemicals, and new materials. Hundreds of people in charge of the company attended.
It is hoped that during the "14th Five-Year Plan" period, the state will increase its efforts to coordinate the control of PM2.5 and ozone, which will surely set off a climax of domestic VOCs control. The sub-sector VOCs control and ozone control are expected to become new areas of expansion. As an annual event for the domestic VOCs monitoring and governance industry, the 3rd China International VOCs Monitoring and Governance Industry Innovation Summit (VOCs Summit 2021) will be held in Suzhou on April 28, 2021, with nearly 400 business leaders from the VOCs industry at home and abroad. , industry professionals and relevant user units gathered together to discuss RTO/RCO, VOCs monitoring technology, activated carbon, photodegradation, recycling and many other hot topics. As an influential manufacturer of ceramic regenerators in the industry at home and abroad, Boxin Environmental Protection was invited by the organizer of the conference to participate in the conference and make a special report.
The 22nd China Environmental Expo was grandly opened on April 20 at the Shanghai New International Expo Center.
