Another invention patent of Xingrui was authorized by the China National Intellectual Property Administration

Recently, another invention patent of Scientific Green(shandong) Environmental Technology Co.Ltd. was authorized by the China National Intellectual Property Administration. The name of this patent is "green environmental protection agent for zero discharge of circulating water" (patent No. ZL201610486565.4).

The present invention relates to the field of water treatment technology, and particularly discloses a green and environmentally friendly agent for zero discharge of circulating water. The green environmental protection agent used for zero discharge of circulating water is characterized by mixing scale inhibitors, corrosion inhibitors, dispersants, surfactants, and fluorescent tracers with water in a certain weight ratio. The present invention not only solves the problem of sewage treatment, but also meets the demand for circulating water in industrial production, greatly saving water consumption; The selected raw materials are environmentally friendly phosphorus free materials that are not prone to causing microorganisms, especially algae, to grow wildly in sewage, and have a certain bactericidal effect. The characteristics of the present invention are low cost per ton of water treatment, easy operation, and the use of a combination of chemical and physical methods. Various complex water qualities such as industrial wastewater and reverse osmosis concentrate are reused as supplementary water, achieving true zero discharge in industrial circulating water systems and turning years of dreams into reality.

At present, the invention has achieved zero discharge in the circulating water system of Weifang Xianda Chemical by using sewage treatment plant effluent as circulating water supplement; The circulating water system of Xinhua Pharmaceutical Shouguang Co., Ltd. adopts reverse osmosis concentrated water, MVR sewage and other materials as supplementary water to achieve zero discharge of the circulating water system. All have achieved low-cost zero discharge of enterprise wastewater.

As of now,Sciengreen Environment has obtained 15 national patent authorizations, including 6 invention patents. In addition, 6 invention patents have entered the substantive examination stage. Its research and development and innovation level are in a leading position in the same industry. Multiple technologies have filled the domestic gap and reached the international leading level, accumulating momentum for the development of the water treatment field and helping to promote the effective implementation of the new and old kinetic energy conversion strategy.
