High and cold region construction sewage treatment system

Abstract

The invention discloses a high and cold region construction sewage treatment system. The high and cold region construction sewage treatment system comprises a sewage treatment system and a heating device for supplying heat to the sewage treatment system; the sewage treatment system comprises a coagulation area, a flocculation area and a sedimentation area which are sequentially communicated; the coagulation area is provided with a sewage treatment system water inlet; the sedimentation area is provided with a sewage treatment system water outlet; the heating device comprises electric heating pipes respectively arranged at the bottoms of the coagulation area and the flocculation area, and a heating belt wound on the outer wall of the sedimentation area. Different heating modes are set for different areas of the sewage treatment system, it is guaranteed that normal operation of the sewage treatment system can be realized at low temperature, and sewage is treated in time.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a construction sewage treatment system and method in an alpine region. Background technique [0002] At present, due to the continuous development of my country's social economy, especially for the need to promote the economic development of border areas, construction projects in high-altitude areas such as Northwest, Northeast, and Southwest my country are increasing, and construction will generate a large amount of sewage, requiring the use of sewage treatment facilities Reduce environmental pollution caused by construction. The construction is temporary, and the sewage generated is also temporary. If the sewage treatment facilities used are fixed facilities, they will be abandoned after the tunnel construction is completed, or even need to be demolished, resulting in a waste of investment. [0003] The flat land for construction in high-altitude areas is usually not large, the ...

Problems solved by technology

The construction is temporary, and the sewage generated is also temporary. If the sewage treatment facilities used are fixed facilities, they will be abandoned after the tunnel construction is completed, or even need to be demolished, resulting in a waste of investment

[0003] The flat land for construction in high-altitude areas is usually not large, the usable area is quite limited, and the traffic is often inconvenient. The sewage treatment facilities need to be efficient, low-consumption, occupy less land, and have a compact structure; The temperature difference is relatively low, and the extreme low temperature can reach -40°C. The sewage treatment facilities and pipelines are easy to freeze, crack and fail to work normally. The simple thermal insulation box cannot solve the problem of integrated equipment used in high-cold regions. Difficulties in the operation of chemical sewage treatment facilities
