Description
Technical Field
The invention relates to the technical field of underground engineering mining method construction, in particular to a movable integrated mining method construction wastewater treatment device.
Background
With the development of economic technology, more and more underground projects such as railway tunnels, highway tunnels, subway tunnels, utility tunnel and the like are constructed. The mining method is one of the main methods for constructing underground works, and is widely used in the field of underground works. When the underground engineering is built by the mine method, a certain amount of construction wastewater is generated at the working surface. The main pollutants of the wastewater are as follows: suspended substances, petroleum, ammonia nitrogen and the pH value is higher. In the past, because of the light environmental awareness, the drainage of underground engineering construction is temporary drainage, and pollution is ignored for a long time. In the design process of underground engineering, only a sedimentation tank and an oil separation tank are generally arranged, and engineering practice finds that the construction wastewater cannot reach the standard at all.
The construction wastewater of the underground engineering is mainly concentrated in the unfinished section of the second lining, namely the area between the construction working surface and the finished section of the second lining, and the wastewater in the area where the second lining is finished is mainly structural water leakage, has water quality similar to that of the underground water, and can be directly discharged. At present, a treatment measure is adopted for construction wastewater by individual underground engineering, but the treatment measure is arranged at the construction opening of the ground or underground engineering, and because the underground engineering space is narrow, the secondary lining unfinished section wastewater and the secondary lining finished section structure water seepage are mixed and then are discharged out of the ground by using a temporary drainage system, so that the actual treatment capacity of the treatment device arranged on the ground covers the secondary lining unfinished section wastewater to be treated and the secondary lining finished section structure water seepage which does not need to be treated, and the actual treatment capacity is extremely large. Engineering practice shows that the processing device arranged on the ground has two results: one is that the cost is too high to be a relay because of the excessive processing scale; the design process capability is too small, and the actual process scale is too large to reach the standard.
In view of the above, there is an urgent need in the field of underground engineering mining construction for a mine construction wastewater treatment device that is convenient to install and move, and can perform in-tunnel treatment on the two-lining unfinished construction wastewater.
