Technological Innovation | Honghu High-tech Successfully Selected as a Specialized, Refined, and Unique "Small Giant" Enterprise in Beijing

Technological Innovation | Honghu High-tech Successfully Selected as a Specialized, Refined, and Unique "Small Giant" Enterprise in Beijing

The Beijing Municipal Bureau of Economy and Information Technology announced the list of the second batch of specialized and new "small giant" enterprises in Beijing in 2021 on March 1, 2022. Hezhong Company was successfully selected as a specialized and new "small giant" enterprise in Beijing. Following its selection as a "specialized and new small and medium-sized enterprise in Beijing" in 2020, Hezhong Company, based on its advantages in technological R&D capabilities, product innovation and application, and market development prospects, has once again been included in the list of specialized and new "small giant" enterprises in Beijing in 2021. This is an affirmation of the company's efforts in innovation capabilities, specialization, and refinement, and the best recognition of the company's comprehensive strength. In January 2021, the Ministry of Finance and the Ministry of Industry and Information Technology jointly issued the "Notice on Supporting the High-Quality Development of Specialized and New Small and Medium-sized Enterprises." The Notice proposes to accelerate the cultivation of a batch of specialized and new "small giant" enterprises that focus on niche markets, focus on their main business, have strong innovation capabilities, and have good growth. It supports key specialized and new "small giant" enterprises to accelerate their listing process. Specialized and new "small giant" enterprises are the best among the specialized and new small and medium-sized enterprises that have undergone layers of screening. They are leading enterprises that are more focused on niche markets, have strong creative capabilities, high market share, master key core technologies, and have high growth. Hezhong Company, founded in 2003, is a world-class supplier of zero-discharge and resource utilization solutions for wastewater, providing users with unique process package design and full-process engineering implementation services. As a national high-tech enterprise and a specialized and new "small giant" enterprise in Beijing, the company's technical products have been repeatedly selected for the "National Advanced Pollution Control Demonstration Technology List, Beijing New Technology and New Products, Beijing Energy-Saving Technology Product Recommendation Catalog, Zhongguancun First (Set) Major Technological Equipment Experiment, Demonstration Project," etc. The company's independently owned intellectual property rights technology and products widely serve large state-owned enterprises, central enterprises, and other heavy industries, with accumulated service to more than 2,000 customers across more than 50 countries. The company attaches great importance to product and technology R&D, adheres to the path of innovation, and pays attention to the qualitative change of technology patent, standardization, and branding. Currently, it has obtained 156 patents. Focus leads to professionalism, and professionalism leads to development. Through in-depth research on industry applications and relying on twenty years of industry experience, we cooperate with industry leaders to develop and apply water treatment products and technologies. We focus on the applicability, convenience, reliability, stability, and economy of product technology, and devote more time and energy to R&D and innovation itself, aiming for specialization, refinement, characteristics, and novelty to accelerate the development of zero-discharge technology in the field of water treatment, promote the iteration and update of industry technology products, and contribute to the development of the industry. The company's products are constantly being developed and upgraded— Filtration system: From traditional small filter cartridges, we have developed the Rizonflow® high-flow filtration system, the first and earliest enterprise in China to develop and apply it. Currently, we have upgraded and developed antibacterial high-flow products and backwashable high-flow products; Water quality monitoring system: We have developed the RizonSDI® full-series SDI water quality monitoring equipment, including fully automatic, semi-automatic, portable, and manual SDI instruments. We are the only company in the world with a full range of products; High-salt wastewater zero-discharge system: The technology is constantly being upgraded. Based on the original process version 1.0 (evaporation crystallization system technology)—Hezhongsi® HEC, we have continuously iterated and upgraded, developing process version 3.0. For power plant wastewater treatment—Hezhongsi® HLTC technology, and for the coal chemical and mine water industries, we have made strong breakthroughs in large and small freezing crystallization technologies, and achieved successful application in several benchmark projects. Hezhong Company's zero-discharge technology, while achieving the goal of zero wastewater discharge, also enables the resource recovery of substances in wastewater. From the purification of 97.5% refined industrial salt of sodium chloride in process version 1.0 to the current process version 3.0, which can simultaneously purify 98.5% first-grade crystalline sodium chloride and 99% first-grade anhydrous sodium sulfate crystalline salt. At the same time, paying attention to the increasingly important energy issue in China, we constantly consider how to save energy and achieve clean production, which are important points emphasized by modern industrial enterprises. The initial starting point of Hezhong Company's research and development of evaporation crystallization system technology also started from this. Hezhong Company is not only a pure environmental protection enterprise, but also a genuine manufacturing enterprise. While continuously upgrading wastewater zero-discharge and resource utilization environmental protection technologies, we aim at the shortcomings of the manufacturing industry, introduce international high-end manufacturing technologies, localize them, break international barriers, reduce technical difficulties and costs, and support high-salt wastewater zero-discharge technology processes from the equipment level. This selection as a "small giant" enterprise is a full affirmation and support of Hezhong Company's more than 20 years of persistence in independent innovation in the field of zero wastewater discharge. In the future, Hezhong Company will, on the basis of the current situation, focus on the shortcomings and weaknesses of the industry, cultivate deeply in the field of niche markets, adhere to the path of innovation, develop more practical new products and technologies, "make up for shortcomings," "strengthen strengths," and "fill gaps" in key areas, achieve high-quality development, deepen the "specialized and new" field, and create more valuable value for the country, the industry, and users.
