Description

Technical Field

[0001] The invention relates to the technical field of polluted surface water treatment and restoration, and in particular to an enhanced biological-ecological modular sewage treatment system. Background Art

[0002] Although artificial wetlands have the advantages of good effects and high ecological landscape benefits, and are widely used as a tertiary deep treatment process for water treatment, they also have prominent problems such as large land occupation, low low-temperature effect, easy clogging, and easy formation of dead water ends. Therefore, targeted optimization is needed to consider issues from the perspectives of increasing stability and hydraulic load, coupling with other processes, enhancing effluent water quality standards, and facilitating installation. By adding new reinforced fillers and pipe network systems, traditional artificial wetland technology can be coupled with technical means such as aeration, and finally integrated into integrated equipment to achieve modular production and flexible installation and application according to water quality requirements.

[0003] At the same time, traditional technologies, including artificial wetlands (such as the Chinese patent technology with publication number CN 109956558 A), etc., have problems such as low automation and few application scenarios. For example, similar to the traditional sewage plant tailwater artificial wetland treatment technology or other technologies (such as the Chinese patent technology with publication number CN 105130015 A), it can only treat sewage with a relatively clear influent concentration range, and cannot automatically determine what operating conditions to adopt in the future (such as aerator start and stop, water inlet mode, different water flow channels, hydraulic retention time HRT adjustment, etc.) according to the water quality range (micro-polluted surface water, sewage plant tailwater, aquaculture wastewater, domestic sewage, etc.) to meet the needs of different objects. Therefore, its application scenarios and scope of use should be continuously expanded. Summary of the invention
