Container type seawater desalination system

Abstract

The invention discloses a container type seawater desalination system, comprising a first container and a second container, wherein a pretreatment system and a reverse osmosis system are arranged in the first container; and a forward osmosis system is arranged in the second container, the reverse osmosis system comprises a reverse osmosis booster pump, a reverse osmosis security filter, a high-pressure pump, an energy recovery device and a reverse osmosis membrane group, and the forward osmosis system comprises a forward osmosis water inlet pump, a forward osmosis security filter, a forward osmosis membrane group and a draw solution water tank. The reverse osmosis technology and the forward osmosis technology are integrated, the produced water quality is high, the operation pressure is relatively low, and the membrane pollution degree is low; an integrated energy recovery device and a high-flow filter element horizontal glass fiber reinforced plastic filter are integrated, and the desalination system is high in energy efficiency and compact in structure; subsystem arrangement and multi-group design are adopted, and the high-pressure pump and the energy recovery device are controlled by variable frequency, so that the operation mode is flexible, the operation flexibility is high, and the adaptability is high; and the desalination system has good economic value and environmentalprotection value.

Description

technical field [0001] The invention relates to the technical field of water resource treatment, in particular to a container-type seawater desalination system. Background technique [0002] Today, with the increasing shortage of fresh water resources, desalination of seawater, as an open source and incremental technology of water resources, has become an important way for countries all over the world to solve the problem of water shortage. Coastal water-deficient cities and islands are actively promoting the construction of seawater desalination projects. The construction process of large and medium-sized seawater desalination systems is relatively complicated, the construction period is long, and the investment is large. It is suitable for areas with concentrated water consumption. The container-type seawater desalination system has the advantages of compact structure, small footprint, less civil engineering workload, short construction period, and rapid layout. It is esp...
