[0002] With the continuous development of the construction industry, green and civilized construction at construction sites has received great attention from the society. In the process of construction, a large amount of construction wastewater and sewage will be generated. Direct discharge will cause great pollution to the environment, so the sewage needs to be treated before discharge. The construction site wastewater mainly comes from concrete mixing, pile foundation construction, decoration construction, equipment cleaning, bathing in living areas, laundry and other links. The composition of wastewater is complex and may contain construction mud, cement slurry, organic matter, heavy metals, oil pollution, suspended solids, etc. Therefore, wastewater treatment needs to adopt appropriate treatment technology for different wastewater components. Through effective wastewater treatment, the environment can be protected, resource waste can be reduced, and it can also help construction companies fulfill their social responsibilities and enhance their corporate image. At the same time, good wastewater treatment can also protect the health of construction workers and create a harmonious construction site environment.

[0003] Existing traditional wastewater treatment usually only has one simple filtering structure, which cannot thoroughly and fully purify the wastewater, resulting in the discharged wastewater still failing to meet the national emission standards, which is easy to cause secondary pollution to the environment. In addition, after long-term use, the activated carbon adsorption plate and filter net will become clogged, which is not easy to clean and affects the subsequent filtering effect. Utility Model Content

The purified water can meet national standards and can be recycled without polluting the surrounding environment. It effectively saves costs, realizes green construction, and meets the strategic goal of sustainable development.
