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] Such as 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 pr...

Abstract

A system and method for ship sewage treatment and resource reuse imitating waves, the system includes: a comprehensive pretreatment pool (1) with a circular structure formed by hydraulic baffles and connections of pipelines, a wave-imitating pre-degradation bed (2), an imitating Sea wave biological bed (3), shallow sedimentation tank (4), imitation natural filter tank (5) and clear water disinfection tank (6), the cross-section of the system is rectangular, preferably square, especially suitable for ships with narrow cabin space Use requirements, efficient and intensive use of limited space, less affected by the shaking of the hull, and can ensure that the processes of pre-settling, degreasing, degradation, adsorption, post-settling, filtration, disinfection and other processes are connected with each other, and division of labor and cooperation give full play to their respective advantages , Significantly improve the sewage treatment effect. It can realize the comprehensive treatment of all kinds of sewage generated by the operation of ships, avoid the difficulties of complex systems and high investment in the separation of various types of sewage, and completely solve the problem of water pollution from ships, achieving impact resistance, high efficiency, low cost, and less maintenance. Purpose.

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...
