Recycling treatment system for treating reclaimed water of sewage plant in synthetic leather industrial area

Abstract

The invention relates to a recycling treatment system for treating reclaimed water of a sewage plant in a synthetic leather industrial area, wherein the system comprises a water inlet device used for injecting sewage into a pretreatment pool, a pretreatment device connected with the water inlet device and used for settling pollutants in the sewage, an ultrafiltration device connected with the pretreatment device and used for filtering organic pollutants in the sewage, a reverse osmosis device connected with the ultrafiltration device and used for separating salt ion pollutants in the sewage, a first detection device arranged at a water outlet of the ultrafiltration device and used for detecting the COD value in the sewage, and a second detection device arranged at a water outlet of the reverse osmosis device and used for detecting the conductivity in the sewage. A central control unit is arranged, and the central control unit adjusts the treatment efficiency of the pretreatment device, the recovery capacity of a first recovery device, the recovery capacity of a second recovery device and the evaporation temperature of an evaporator according to the COD value and the electrical conductivity in wastewater, so that the reclaimed water meets the preset standard.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a water reuse treatment system for treating synthetic leather industrial park sewage plants. Background technique [0002] Reclaimed water reuse technology refers to the centralized treatment of domestic waste and sewage (bathing, washing, laundry, kitchen, toilet) of residents in the community, and reusing to a certain standard for green irrigation, vehicle washing, road washing, and family toilets in the community. Washing, etc., so as to achieve the purpose of saving water. With the deepening of the research on the reuse of reclaimed water, the treated reclaimed water has been applied in the advanced treatment of reclaimed water in thermal power plants. Advanced treatment of reclaimed water is the most fundamental means to slow down the problems of corrosion, scaling and microbial growth. Due to the complexity of reclaimed water quality and strict water standards, it is general...
