Project introduction: The company's main businesses are mainly divided into environmental protection, energy conservation and consulting services. The company fully integrates and absorbs international advanced energy management concepts and mature energy management technologies, and has established extensive cooperation with industry associations, societies, scientific research institutes, universities, design units and government energy conservation agencies. Through professional and effective energy management services, the company's energy conservation management level has become one of the most professional companies in the energy conservation and emission reduction industry.

Main technical indicators: HM-10 for small projects: The design scale of small projects is about 10 tons/hour. The system operates continuously, with two sand filters, two G columns and two K columns each, one in use and the other for standby. Depending on the concentration of heavy metals in the incoming water, the interval between the two regenerations is about 15-35 days. It can be used for about two and a half to three and a half years without replacing the filter material. Medium-sized project HM-30: The design scale of the medium-sized project is approximately 30 tons/hour. The system operates continuously, with two sand filters, one in use and the other for standby. Three G columns and three K columns are connected in series. Regeneration is carried out when the adsorption of the No. 1 column is saturated, and placed behind the No. 3 column after regeneration. The original No. 2 pillar was changed to No. 1, and the original No. 3 pillar was changed to No. 2. Depending on the concentration of heavy metals in the influent, the interval between two regenerations is about 15~35 days. It can be used for about two and a half to three and a half years without replacing the filter material.

Current application situation: The hardness of the wastewater discharged to the terminal from the pickling wastewater treatment stations such as steel mills, hot rolling mills, and cold rolling mills of Baosteel Special Steel Co., Ltd. is about 2500 mg/L, which is the main reason for the high hardness of the terminal wastewater. As a result, the terminal's wastewater recycling capacity has been significantly reduced, and the fresh water consumption per ton of steel has also been greatly increased. To this end, Yunhuo Company has built an advanced treatment device for industrial circulating water treatment facilities in the factory area to implement hard removal treatment on industrial circulating water to improve wastewater reuse rate.

Application prospects of "civilian joining the army" or "military conversion": It can be used for military industrial wastewater treatment, can improve the reuse rate of wastewater, save energy and protect environment.
