Title:
WASTEWATER INTERCEPTION CENTRALIZED TREATMENT SYSTEM AND TREATMENT METHOD FOR RIVER CHANNEL REGULATION
Document Type and Number:
WIPO Patent Application WO/2021/098731
Kind Code:
A1
Abstract:
A wastewater interception centralized treatment system and treatment method for river channel regulation. Said treatment system comprises a wastewater interception pipe network (1), an integrated strengthened treatment assembly (2), and an ecological restoration assembly (3). Said treatment system converts non-point source pollution into point source pollution by means of the wastewater interception pipe network (1), performs centralized, high-efficiency, and strengthened treatment by means of the integrated strengthened treatment assembly (2) to remove a large amount of sludge sediment, ammonia nitrogen, chemical oxygen demand, total phosphorus, and biochemical oxygen demand from wastewater, performs primary sedimentation and filtration by means of flow diverting weirs (301) in the ecological restoration assembly (3), and enables wastewater to flow through artificial ecological floating islands (302) and artificial aquatic weeds (303), and uses developed root systems of aquatic plants (302b) and biofilm carriers (303a-22) to perform secondary biodegradation on wastewater, so as to realize wastewater purification. Said treatment system and treatment method use wastewater interception and centralized treatment, achieving thorough direct discharge control of wastewater and a good scale effect, and combine a biological filter bed process and ecological restoration techniques, further effectively preventing spread of pollutant from discharge ports by means of an ecological effect while ensuring the efficient and strengthened treatment.
