The company is a national high-tech enterprise focusing on the R & D, manufacturing and application technology of membrane separation equipment, high-performance membrane modules and other products, and providing customers with comprehensive solutions for high concentration wastewater treatment and cleaner production. Based on its many years of application experience, technological R & D innovation and in-depth understanding of the characteristics of sewage and wastewater in China, the company has mastered the core technologies such as modular membrane separation equipment manufacturing technology, high-performance membrane module manufacturing technology, landfill leachate membrane treatment technology, advanced treatment of industrial wastewater and zero discharge treatment technology, and developed widely used in landfill leachate treatment Membrane technology series products in the fields of industrial wastewater treatment and reuse and industrial process separation, so as to meet the growing market demand for stable and up to standard discharge of high concentration wastewater, harmless treatment and efficient separation of industrial processes.
The company's main products and services are membrane separation equipment, membrane components and consumables, and high concentration wastewater treatment services. (III) core technology and research and development
1, core technology and advanced nature
As a national high-tech enterprise with membrane technology as the core and providing customers with professional solutions, the company has core technology in the manufacturing of high-performance membrane components, integrated research and development of membrane technology and process, manufacturing, commissioning, operation and maintenance of complete sets of membrane separation equipment, etc.
Driven by technological innovation, the company has achieved a series of scientific research achievements and honorary titles. As of the signing date of the listing sponsor, the company and its subsidiaries have a total of 102 patents, including 23 invention patents, 73 utility model patents and 6 appearance patents.
The main technical level and characteristics of the company are as follows:
(1) Modular membrane separation equipment manufacturing technology
Based on the concepts of "engineering equipment" and "high concentration sewage and wastewater treatment service", the company carries out modular treatment of membrane separation equipment, which overcomes the shortcomings of large civil engineering demand, long product delivery time, unstable quality control and poor flexibility under the traditional environmental pollution treatment mode; At the same time, it is also conducive to the establishment of a stable supplier system, the monitoring and control of relevant equipment, the improvement of supply chain efficiency and production efficiency and the reduction of production costs.
(2) Manufacturing technology of high performance membrane module
Membrane module is one of the key components in the application of membrane technology. Through independent research and development, the company has formed a series of membrane module product echelons with different indicators such as membrane material, membrane pore size, membrane flux and pressure resistance, expanding the application scope and field of traditional membrane modules; By optimizing the design of membrane module, its service life and interception performance are improved; By adopting the operation mode of automatic production and integrating electromechanical integration, precision manufacturing technology and automatic visual inspection technology, the product assembly efficiency and yield are greatly improved.
(3) Landfill leachate treatment and full quantitative treatment technology
The company has many years of experience in the standard discharge treatment of landfill leachate, and has the treatment technology with "biochemical + membrane treatment" and "full membrane treatment" as the core process. On this basis, the company has formed the reduction and full quantitative treatment technology of landfill leachate, and formed the ready-made products. The reduction treatment adopts "hpro + dtnf" and other high-power concentration membrane equipment process, which can reduce the water volume of concentrated solution by about 50%; The "hpro + (dtnf) + low temperature negative pressure evaporation + solidification" process is adopted for full quantitative treatment, which can finally realize the full quantitative treatment of landfill leachate.
The above technologies and processes adopt high-performance and independently replaceable membrane modules, which can operate stably under the condition of high CODcr and high scaling in concentrated water. At the same time, it can effectively avoid the problems of high energy consumption and pipeline corrosion, and reduce the system investment and maintenance and operation cost of customers.
(4) Treatment and zero discharge technology of industrial high concentration wastewater
In the field of advanced treatment of industrial wastewater, the company has formed an "external tmbr + Advanced Treatment NF / Ro" treatment process. In view of the sensitive characteristics of industrial wastewater treatment to operation cost, the company adopts external MBR membrane system and introduces the control combination including variable frequency control flow rate, multi pipe series, on-line cleaning and other processes, so that the membrane separation equipment has higher economy and reliability; NF / Ro advanced treatment unit adopts MT membrane module with strong anti pollution and wide flow channel, and uses multi-stage internal circulation combined process to improve water recovery and resource utilization.
In the field of zero discharge treatment of industrial wastewater, the company has formed a core treatment process of "tuf hard removal + MT / St / dt high-power concentration". Among them, tuf is the process of directly filtering the wastewater added with hardener with tubular membrane tuf. This process has the advantages of no additional coagulant aid and flocculant, less pollution and low site investment. At the same time, the multi-stage internal circulation combined process designed and developed by the company can combine st and DT in the same unit system, which has the characteristics of high throughput of St membrane module and anti pollution of DT membrane, which can reduce the system investment and improve the concentration multiple.
