Container type sewage treatment system

Abstract

The invention discloses a container type sewage treatment system which solves the problem that a concentrated water treatment effect is poor in container type sewage treatment equipment. The container type sewage treatment system comprises a container shell in which a raw water booster pump, a cleaning water tank, a scale inhibitor device, a high-pressure pump, a circulating pump, a same-end water inlet / outlet separation filtering membrane column, a power distribution cabinet and a control cabinet are arranged, wherein a water inlet pipeline and a water outlet pipeline are arranged on the lower part at the rear end of the container shell; a water inlet end of the raw water booster pump is connected with the water inlet pipeline, and a water outlet end of the raw water booster pump is connected with a water inlet end of the high-pressure pump through a first cartridge filter; a water inlet end of the same-end water inlet / outlet separation filtering membrane column is connected with a water outlet end of the high-pressure pump through the circulating pump; a water outlet end of the same-end water inlet / outlet separation filtering membrane column is respectively connected with the water inlet end of the circulating pump and the water outlet pipeline; the scale inhibitor device is connected between the first cartridge filter and the high-pressure pump; and a water outlet end of the cleaning water tank is connected with the water inlet end of the circulating pump. According to the system, the raw water recycling rate can be greatly improved.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a container type sewage treatment system. Background technique [0002] Reverse osmosis (referred to as RO) is a membrane separation technology developed in the past 20 years. Its basic principle is: under the action of raw water at a pressure higher than the osmotic pressure difference, water enters the membrane through a semi-permeable membrane. The low pressure side, while the salt in the raw water is blocked on the high pressure side of the membrane and discharged with the concentrated water. Most of the soluble salts and some organic matter in the raw water can be removed by RO technology. After the raw water is treated by RO technology, it is divided into two parts: primary pure water and RO concentrated water. Using RO technology to treat raw water, the recycling rate of raw water can only reach up to about 70%, and about 30% of RO concentrated water is still discharged. At p...
