Description

Technical Field

[0001] The present invention relates to the technical field of building engineering construction, and in particular to a green construction wastewater treatment device and a use method thereof. Background Art

[0002] Green construction refers to the maximum conservation of resources, environmental protection and pollution reduction throughout the life cycle of the building, providing people with healthy, applicable and efficient use of space, and buildings that coexist harmoniously with nature. Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction work is done is called the "construction site" or "construction site", also called the construction site; During the construction process, a large amount of sewage will be generated. These sewage contain various impurities and harmful substances, such as metal ions, suspended solids, etc. If they are discharged directly, it will not only pollute the environment, but also cause waste of resources. Therefore, how to deal with these sewage has become a problem to be solved. At present, the common treatment method is to use physical filtration or chemical agents for treatment, but these methods have some problems. Physical filtration can only remove large particles of impurities, and cannot effectively remove small particles of impurities and harmful substances; although chemical agents can remove harmful substances, they need to be added regularly, the operation is complicated, and secondary pollution may occur.

[0013] A method for using a green construction wastewater treatment device, further comprising the following steps: Step 1: When the sewage generated during the construction process is introduced into the sewage pool, the sewage is first filtered through the sand and gravel box and then collected into the sewage pool. As the sewage in the sewage pool gradually increases, the depth of the sewage will become deeper, and the float in the sewage pool will increase its vertical height as the sewage increases; Step 2: When the float rises, the gravel box and the conical mouth connected to the float will also rise. During the rising process of the conical mouth, the inner box can be driven to move up along the fixed seat. During the upward movement of the inner box, the rack on the outside of the inner box will drive the gear to rotate.

The impurities and metals in the sewage can be cleaned.

[0014] The present invention has the following beneficial effects: (1) According to the present invention, after sewage is generated during construction, it is introduced into the sewage pool, and then the sewage enters the gravel box. After the sewage enters the gravel box, it is initially filtered, and the impurities in the sewage can be filtered. After entering the sewage pool, the sewage will gradually accumulate, and the depth of the sewage will gradually increase. After a float is placed on the sewage, the float will rise with the sewage. The float is set on the conical mouth, and the conical mouth and the gravel box will also rise. During the rising process of the conical mouth, the inner box will be driven to move. When the inner box moves, the rack will drive the gear to rotate. When the gear rotates, the blocking plate will open, and the medicine in the storage box will enter the inner box and fall onto the partition. As the conical mouth rises, the partition does not move, and the inner box will rise away from the partition. The medicine on the partition will fall into the sewage pool after being unrestricted, thereby cleaning the metal and impurities in the sewage pool, making the sewage cleaner and preventing pollution damage.

[0015] (2) The present invention can discharge the medicine in the storage box by setting the protrusion. The protrusion is provided with a protrusion seat, the protrusion seat is installed with a rotating rod, the rotating rod is installed with a blocking plate, and the rotating rod is provided with a gear.
