Ash sluicing water treatment and recycled water reuse system for ships

Abstract

The invention relates to the technical field of sewage treatment, and in particular relates to the technical fields of purification treatment of domestic sewage on ships and recycled water reuse technology. The invention aims at providing a sewage treatment and recycled water reuse system for ships, and the system can break through the restrictions by the ships, can be hardly affected by the hull shaking and can make full use of water resources. The system includes an ash sluicing water treatment system and a recycled water reuse system. The ash sluicing water treatment system in accordance with the direction of flow includes an ash sluicing water collecting cabinet, a biochemical cabinet, a crushing pump, an MBR film cabinet, a water production pump, a disinfection cabinet and an intermediate water cabinet; part of the water in the intermediate water cabinet flows through a backwash pump into the MBR membrane cabinet, and the other part enters the recycled water reuse system. The recycled water reuse system in accordance with the direction of flow includes a close filter, a UV sterilizer, a booster pump, an RO film, a recycled water cabinet, a UV sterilizer, a recycled water supply pump, and a water recycled pressure tank; and all parts of the system are connected through pipes.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to the technical field of purification treatment of domestic sewage on ships and reuse of reclaimed water. Background technique [0002] With people's emphasis on environmental protection, the sewage on ships can only be discharged to the sea after treatment, so as to avoid pollution to the marine environment. Due to the characteristics of the ship itself, it is impossible to install an ordinary sewage treatment system on the ship, because this kind of system often has problems such as large space occupation, water consumption, power consumption, odor overflow, easy blockage, and difficult maintenance. The existing domestic sewage treatment system of ships mostly adopts biochemical method, or physicochemical method, or electrolysis method; traditional biochemical treatment uses aerobic microorganisms to degrade under the condition of sufficient oxygen, and then separates so...

Problems solved by technology

Due to the characteristics of the ship itself, it is impossible to install an ordinary sewage treatment system on the ship, because this kind of system often has problems such as large space occupation, water consumption, power consumption, odor overflow, easy blockage, and difficult maintenance.

The existing domestic sewage treatment systems of ships mostly adopt biochemical method, or physicochemical method, or electrolysis method; traditional biochemical treatment uses aerobic microorganisms to degrade under the condition of sufficient oxygen, and then separates solid and liquid through precipitation, which has a better effect. However, the volume of the device is large, it is difficult to arrange in the limited cabin, and it is easily affected by the shaking of the hull and hydraulic shock to affect the quality of the effluent water
