Large water movable multifunctional sewage treatment device and sewage treatment method

Abstract

The invention discloses a large water movable multifunctional sewage treatment device and a sewage treatment method. The large water movable multifunctional sewage treatment device comprises a main hull. A plurality of cabins are arranged in the main hull and include an engine room, sewage storage cabins and sewage technological process cabins; a lightering distribution station and a plurality ofsewage treatment technological devices are arranged on a main deck of the main hull, and the lightering distribution station is connected with the sewage treatment technological devices by deck pipe systems and is connected with the sewage storage cabins and the sewage technological process cabins by pipelines in cabins; a technological centralized control room which is connected with the lightering distribution station and the sewage treatment technological devices is arranged on the main deck. The large water movable multifunctional sewage treatment device and the sewage treatment method have the advantages that operation environments, technical specifications of classification societies, sewage treatment standards and techniques and the like are comprehensively considered, accordingly,the large water movable multifunctional sewage treatment device can quickly respond and can cope with different types of sewage treatment purification, and water can be directly drained in surroundingwater areas after reaching standards; service targets are extensive, and the large water movable multifunctional sewage treatment device does not occupy lands, fast in investment and building, is flexible, convenient and speedy, can quickly respond and can be maneuvered in place.

Description

technical field [0001] The invention relates to water sewage treatment, in particular to a large-scale water mobile multifunctional sewage treatment device and a sewage treatment method that serve the needs of sewage treatment along rivers, coasts, and offshore oil platforms. Background technique [0002] At present, the economically developed areas along the coast and the river in my country have precious land resources. Specific factories and living areas built along the river and the coast often face difficulties in discharge and treatment of sewage. The construction of land sewage treatment plants (sewage storage pools, process pools and sewage treatment equipment) will take up precious resources. The land surface and land space; the sewage treatment of crude oil extraction fluid on offshore oil platforms will also occupy limited platform space, resulting in a waste of platform resources; currently the sewage discharge of ships in the port area is strictly restricted, and ...

AI Technical Summary

Problems solved by technology

[0004] In terms of the types of sewage to be treated, the contents of sewage bodies in ship port areas, specific factories, living areas, and offshore oil platforms are different. The current sewage treatment plants often only target one type of sewage body treatment, and cannot handle multiple types of sewage bodies. , so there is a need for a large-scale equipment and method that can be compatible with a variety of sewage bodies, can move to cover a certain coastal area along the river, and has a certain emergency response capability to deal with a variety of sewage treatment
