More preferably, the fine filter includes a sand filter, an activated carbon filter, a fiber filter, a membrane filter, or a metal filter.
The industrial wastewater reverse osmosis treatment recycling system provided by the embodiment is arranged at the tail end of a sewage treatment field.
Firstly, water from a water outlet tank at the tail end of a sewage treatment plant is lifted to intercept suspended matters, organic matters, colloid, sediment and the like in the water by a quartz sand filter, impurities in the water are physically adsorbed by an activated carbon filter, then filtered by a precision filter and an RO membrane by a high-pressure pump, clear water enters a recycling water tank for storage and recycling, and high-concentration water flows back to the sewage treatment plant for treatment.
After the treatment by the filtration and reverse osmosis process, the quality of the clear water outlet reaches the quality requirement of industrial water, and the water can be used as circulating water for supplementing water and a pump of a sewage treatment field for cooling, dosing and recycling, thereby saving fresh water resources, reaching the sewage reduction emission, saving the purchase amount of fresh water by 15000 tons each year and effectively relieving the water resource deficiency dilemma of companies.
Specifically, the quartz sand filter utilizes the fine quartz sand filter material filled in the filter, when the inflow water flows through the filter layer from top to bottom, suspended matters and viscose particles in the water are removed, so that the suspended matters in the water are removed, the turbidity of the water is reduced, and the purpose of filtering is achieved.
