Embodiment Construction

[0047] The application will be further described below in conjunction with the accompanying drawings.

[0048] The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present application.

[0049] like figure 1 As shown, a wave-like ship sewage treatment and resource recycling system includes: a comprehensive pretreatment pool 1 with a circular structure formed by hydraulic baffles and connections through pipelines, a wave-like pre-degradation bed 2, a wave-like biological bed 3, Shallow sedimentation tank 4, imitation natural filter tank 5 and clean water disinfection tank 6. The cross-section of the wave-like ship sewage treatment and resource recycling system is rectangular, preferably square, which especially meets the needs of ships with narrow cabin space, efficiently and intensively utilizes the limited space, and ensures that the space between the pools is The pre-s...

Abstract

The invention discloses a sea wave imitating ship sewage treatment and resource recycling system and method. The system comprises a comprehensive pretreatment tank (1), a sea-wave-imitating pre-degradation bed (2), a sea-wave-imitating biological bed (3), a shallow sedimentation tank (4), a nature-imitating filter tank (5) and a clear water disinfection tank (6) which are communicated through pipeline hydraulic baffling to form a concentric-square-shaped structure. The cross section of the system is rectangular, and is preferably square, the system particularly meets the use requirements of ships with narrow cabin spaces, efficiently and intensively utilizes limited spaces, is slightly influenced by shaking of ship bodies, can ensure that processes of pre-sedimentation, oil removal, degradation, adsorption, post-sedimentation, filtration, disinfection and the like are connected with one another among the tank bodies and exert respective advantages through division of work and cooperation, and remarkably improves the sewage treatment effect. According to the invention, various sewage generated by ship operation can be comprehensively treated, the difficulties of complex system and high investment in quality-divided treatment of various sewage are avoided, the problem of ship water pollution is thoroughly solved, and the purposes of impact resistance, high efficiency, low cost and less maintenance are achieved.

Description

technical field [0001] The invention belongs to the technical field of transportation and environmental protection, and in particular relates to a system and method for sewage treatment and resource recycling of ships in inland rivers and coastal areas. Background technique [0002] With the promulgation and implementation of China's national standard "Ship Water Pollutant Discharge Control Standard" (GB 3552—2018), the five-day biochemical oxygen demand (Biochemical oxygen demand, Biochemical oxygen demand, BOD for short) of sewage discharged from ships, if carried out The time of biological oxidation is five days, which is called five-day biochemical oxygen demand, or BOD for short. 5 ), suspended solids (Suspended Solids, SS for short), heat-resistant coliforms and other pollutants discharge requirements are becoming more and more stringent, and chemical oxygen demand (Chemical Oxygen Demand, COD for short), total nitrogen (Total Nitrogen, Requirements for indicators suc...
