Abstract

The invention discloses a combined assembly type tunnel wastewater treatment device, which comprises more than one sub-box module, the more than one sub-box modules are sequentially communicated through connecting pieces, a wastewater treatment unit is arranged in the sub-box module, and the wastewater treatment unit comprises a dehydration dosing sub-box assembly or a rotational flow sand setting sub-box assembly, or a coagulation sludge discharge sub-box assembly or an efficient precipitation sub-box assembly; the connecting piece comprises a water inlet pipe flange connecting assembly and a water outlet pipe flange connecting assembly, wherein the water inlet pipe flange connecting assembly is arranged on the first end face of the sub-box module; the water outlet pipe flange connecting assembly is arranged on the second end face of the sub-box module; and the first end surface and the second end surface of the sub-box module are opposite surfaces. The device is modularized, small in occupied area, capable of being assembled, high in automation degree, low in cost, easy to maintain and capable of being repeatedly transferred and used, and the design requirements of different areas and different inlet and outlet water quality indexes are met.

Description

technical field [0001] The invention relates to the technical field of urban or railway tunnel wastewater collection and treatment, in particular to a combined assembled tunnel wastewater treatment device and a wastewater treatment system. Background technique [0002] With the increasing requirements for environmental protection, the wastewater generated during the construction and operation of the tunnel project shall not be directly discharged into the environment. Especially in the process of tunnel engineering construction, due to geological conditions, construction methods and other processes, it is inevitable to generate wastewater. In general, suspended solids, pH, chemical oxygen demand, ammonia nitrogen, total phosphorus, and petroleum in tunnel construction wastewater are important factors that cause environmental problems and ecological damage. This kind of waste water mixed with various pollutants in the tunnel construction process must be treated to meet the s...
