Abstract

The invention relates to the field of industrial sewage treatment, and in particular to a sewage treatment device and a tunnel wastewater treatment system and a method. The tunnel wastewater treatment system comprises an adjusting tank, a conveying device, a mixer, a sewage treatment device and a clean water tank, wherein the adjusting tank, the conveying device, the mixer, the sewage treatment device and the clean water tank are connected in sequence through pipelines; and the sewage treatment device comprises a flocculation tank, a precipitation tank and a filtering tank. The invention aims to provide the sewage treatment device and the tunnel wastewater treatment system and the method, and the problems that a conventional tunnel wastewater treatment technique is too simple, process parameters are not reasonably designed, the discharged water retention time is short, the reaction speed is slow, the quality of effluent is not stable and up-to-standard emission cannot be ensured, are solved.

Description

technical field [0001] The invention relates to the field of industrial sewage treatment, in particular to a sewage treatment device and a tunnel wastewater treatment system and method. Background technique [0002] With the rapid development of the country and the needs of social transportation, the construction of tunnels has increased dramatically, and tunnel projects are often located in mountainous and hilly areas that are not plains, and some are even in drinking water sources or water conservation areas. During the construction process, a large amount of water will be generated. If construction sewage is not treated and discharged, it will cause water environment pollution in mountainous areas. The sources of sewage during tunnel construction mainly include the following: during the tunnel opening process, water gushes generated when passing through unfavorable geological units; construction equipment, such as sewage generated by drilling rigs, etc.; a small amount of...
