The Development Course of Changsha Huashijie Environmental Protection Technology Development Co., Ltd.

Our company was established in July 2000, aiming to become a professional technology-based environmental protection company. The first on-line monitoring system of flue gas wastewater in Hunan Province was built, and it was selected as a technical support unit to undertake professional training of environmental protection leaders in provinces, cities and counties and environmental on-line monitoring technology in key enterprises.

In 2003, through the technical optimization and product appraisal of Hunan Environmental Protection Bureau, our company undertook the construction of the environmental online monitoring system of the first batch of key pollutant discharge enterprises, and simultaneously launched the self-developed "Earth Watcher" environmental online monitoring system, which was selected as the unified data communication management platform of Hunan environmental online monitoring system.

In 2005, our company took the lead in launching a full range of online monitoring instruments for heavy metals in China, which filled the gap in China, undertook the preparation of technical standards for online monitoring systems for heavy metals, and developed into an online environmental monitoring instrument manufacturer with independent intellectual property rights and the most complete parameters in China.

In 2006, the company actively explored the national market and achieved good results in Guangxi, Guangdong, Henan and other provinces and cities. In the same year, through the comprehensive evaluation of technical strength and service ability, our company was selected as the third-party socialized operation unit of online monitoring system in Hunan Province, and took the lead in undertaking the independent operation of online monitoring system of provincial pollution sources in China.

In 2007, our company developed from pollution source terminal monitoring to environmental management, and undertook the first demonstration project of heavy metal pollution prevention and control in Xiangjiang River Basin, a major scientific and technological project of energy saving and emission reduction in Hunan Province, which successfully realized the company's in-depth development into a comprehensive environmental protection technology company.

In 2008, we developed a series of industrial wastewater treatment technologies and flue gas treatment technologies to meet the growing and expanding needs of customers and expand new environmental protection technology fields, so as to have stronger technical capabilities to provide customers with overall solutions!

Memorabilia of company development

In July 2000, Huashijie Technology was established.

In April of 20001year, the first on-line monitoring system of flue gas wastewater in Hunan province was built, and the brand building of "Hua Shijie" began.

In September 2002, our company and GTZ jointly held an online environmental monitoring training course, which was attended by provincial, municipal and county environmental protection bureaus and heads of large enterprises.

In May 2003, Huashijie Technology officially settled in Changsha High-tech Development Zone, and was rated as a high-tech enterprise by the High-tech Development Zone and the Provincial Science and Technology Department.

In May 2004, our company launched a self-developed "Earth Guardian" environmental online monitoring data communication platform. In June, "Earth Watcher" was selected as the unified data communication platform of Hunan environmental online monitoring system, and it was applied and popularized in Guangdong, Guangxi, Henan, Jiangxi and other provinces. The system was supported by the Innovation Fund of the Ministry of Science and Technology in 2005.

In July, 2005, our company took the lead in launching a series of online heavy metal monitors independently developed in China, which filled the gap in China.

In September, 2005, in the comprehensive renovation of the "Manganese Triangle" area supervised by the Ministry of Environmental Protection, our online monitoring instruments for total manganese and hexavalent chromium were widely used in this area, and the online monitoring of environmental protection bureaus at the national, provincial, municipal and county levels was realized for the first time through the "Earth Watcher" environmental online monitoring data communication platform, which played an important role in pollution remediation in this area.

In March, 2006, our company undertook the key scientific and technological research project of Hunan Province-"Development and Research on Online Monitoring Technology of Total Cadmium in Xiangjiang River Basin" jointly funded by Hunan Science and Technology Department and Hunan Environmental Protection Bureau, and successfully passed the appraisal of scientific and technological achievements in February, 2006, filling the technical gap of online monitoring of heavy metals in river sections in China.

In May 2006, our company passed the ISO900 1:2000 international quality management system certification, and established the ISO900 1 quality management system to ensure strict quality control of products from research and development, production to construction and maintenance.

In August 2006, Hunan Province took the lead in starting the automatic monitoring system of pollution sources to operate independently. Through the comprehensive evaluation of the company's qualification, technical strength, performance and after-sales service ability, we finally chose our company as the third-party socialized operation unit. Our company took the lead in establishing a high-standard operation monitoring center to grasp the operation of the online monitoring system of pollution sources in the province in real time and build a monitoring and early warning system of pollution sources in the province.

In September, 2006, our company started to build an online monitoring system for heavy metals in wastewater of large national nonferrous smelting enterprises such as Zhu Ye Group, Shuikoushan Nonferrous Group, Xikuangshan Mining Bureau and Zhongjin Lingnan Shaoguan Smelter, which provided an accurate, stable and economical monitoring means for heavy metal pollution monitoring and early warning and pollution reduction of large national nonferrous metallurgical enterprises.

From June 5, 2007 to 2007 10, our company's heavy metal online monitor was successively rated as "national key new product", "national key environmental protection practical technology" and "national key environmental protection technology demonstration project", and the enterprise standard of heavy metal online monitor compiled by our company was listed as the local standard of Hunan Province.

In June 2007, our company successfully entered the field of automatic monitoring and control of nonferrous metallurgy process. Our company took the lead in developing an online monitor for cobalt, germanium, cadmium, copper and iron in the purification section of zinc hydrometallurgy, and applied it to the automatic monitoring of zinc hydrometallurgy purification process in Zhuzhou Smelter. TP, Cl- and S2 on-line monitors for tungsten industrial process control have been applied in the process adjustment of Chenzhou Mining Tungsten Plant.

In June 2007, our products were successfully selected into the bidding project of online monitoring and construction of state-controlled pollution sources in Guangxi Zhuang Autonomous Region. In August 2008, it was successfully selected in the bidding project of online monitoring and construction of state-controlled pollution sources in Heilongjiang Province. Two finalists further consolidated Huashijie Technology's leading position in the field of environmental online monitoring.

In June 2008, our company undertook the industrialization project of the national torch plan-"Industrialization of monitoring and early warning equipment for heavy metal pollution such as total cadmium in water".

In August 2008, our company participated in the 863 scientific and technological key project-"Research and development of automatic monitoring of zinc hydrometallurgy process".

In September, 2008, our company built the first automatic monitoring station of water quality in Hunan Province-Qingshuijiang section (heavy metal) automatic monitoring station, which established our company's leading position in the construction of drinking water safety early warning system and marked our company's successful entry into the field of automatic monitoring of surface water.

In March 2009, our company completed the first comprehensive demonstration project in Xiangjiang River-the electrochemical treatment project of zinc smelting wastewater in the fourth smelter of Hunan Shuikoushan Nonferrous Metals Group.
