In recent years, Shougang Machinery & Electric has conformed to the requirements of environmental protection development in the new situation responded to the call of national policies, vigorously entered the environmental protection field, and further promoted the environmental protection-related industries, especially in conjunction with the government's policy guidance on promoting the treatment of urban and rural sewage sludge, and focused on the surrounding areas in Beijing. Counties and key provinces in the region have improved their ability to provide environmental protection services and contribute to the “rejuvenation strategy for rural areas”.

A few days ago, the reporter went to the upper reaches of Yanqi Lake - Changyuan Village, Yanqi Town, Huairou District, Beijing City. Changyuan Village is built on the upper reaches of Yanqi Lake and is a village with more than 400 households and a population of more than 1,200. Villagers’ domestic sewage is directly discharged into the river and causes pollution to the river. In order to govern rural domestic sewage, Shougang Machinery & Electric has independently developed, designed and manufactured 16 sets of containerized integrated village and town sewage treatment equipment and put them into use in 5 villages and 13 sites. The daily processing capacity ranges from 30 to 120 tons.

The reporters stood at the commanding heights in Changyuan Village and saw four "big boxes" of sewage treatment equipment located at the edge of the river channel in operation, and the clear water flowed into the river.  According to Zheng Guoqing, deputy chief engineer of Shougang Machinery & Electric Complete Equipment Subsidiary, the integrated village and town sewage treatment equipment is divided into three separate sections, which are the anoxic tank, aerobic tank and equipment room. The equipment room adopts MBR technology. MBR is a traditional improved process that combines the activated sludge process with the integrated submerged membrane separation system. The solid-liquid separation process using the membrane module replaces the traditional settlement process and can effectively remove solid suspended particles and organic particles. Particles and organic particles are used for non-drinking purposes such as greening, rinsing, and replenishing ornamental water after the treatment of urban sewage and industrial sewage.

The domestic sewage discharged by rural residents includes human waste, washing, bathing, kitchen waste water etc. Compared with urban domestic sewage, rural domestic sewage is scattered with relatively high concentration of pollutants and large differences in water volume. According to the Beijing local standard “DB11/307-2013 Integrated Discharge Standard for Water Pollutants”, the discharge limit of water pollutants discharged into the surface water bodies by the village sewage treatment stations is the most stringent standard in the country. After testing, the domestic sewage treated by Shougang's electromechanical sewage treatment equipment in towns and villages all reached the emission standards set by Beijing Municipality.

Ms. Liu, a resident at Changyuan Village said, “In the past, the river was dirty and stinky. Now the situation becomes better with sewage treatment stations. Each family has a sewage pool. All the domestic sewage is dealt with together. Now the river isn’t stinky. What a great change.” Shougang Machinery & Electric has made positive contributions to improving the ecological environment of the capital and further demonstrated Shougang’s green corporate image and political responsibility. Being involved in the field of sewage treatment is the need for the transformation and development of the enterprise, the manifestation of the heavy responsibility of the state-owned enterprise and the concrete practice for the national strategy.

Shougang Machinery & Electric is deeply cultivating in the environmental protection sector, with the guiding ideology of "three strengths to achieve three upgrades". It makes effort in the “technical process”, “front-end market” and “back-end market” to continuously expand its business scope and participation. Two categories of products covering sewage and sludge treatment are preliminarily developed, and the development direction of high end, industrialization, serialization, differentiation and branding of environmental protection products are further established. A large number of environmental protection equipments have achieved significant progress and fruitful results.
