Description

Processing apparatus for removing organic matters in RO concentrated water by biochemical method

Technical Field

The utility model relates to a biochemical treatment technical field specifically is a biochemical method gets rid of processing apparatus of organic matter in the dense water of RO.

Background

As a water treatment process, the Reverse Osmosis (RO) membrane technology has the advantages of economy, high efficiency, simple and convenient operation, small occupied area and the like compared with the traditional water treatment method, and is widely applied to the fields of seawater and brackish water desalination, pure water preparation, chemical product concentration and recovery and the like. With the increasing variety and quality of membranes and the continuous improvement of equipment, reverse osmosis technology is increasingly widely applied in the fields of urban sewage recycling, industrial wastewater treatment and the like in recent years. Particularly, the advanced treatment is carried out on the secondary biochemical effluent by the ultrafiltration-reverse osmosis process, so that the reclaimed water is recycled and adopted by many domestic enterprises, thereby saving water resources and reducing the discharge amount of wastewater.

In general, the actual water yield of the reverse osmosis process is generally 75%, and about 25% of concentrated water is produced. The concentration of the pollutants in the concentrated water is about 2-3 times of that in the inlet water, so that the organic matters in the concentrated water are properly treated before the concentrated water is discharged to natural water or recycled.

At present, the degradation and removal method of the RO concentrated water organic matter mainly comprises coagulating sedimentation, activated carbon adsorption, a biological method, iron-carbon micro-electrolysis, an advanced oxidation method and the like. Among them, the biological method has a lower operation cost than the physical and chemical method and is most commonly used. However, since the biodegradability of the RO concentrated water is generally poor, it is necessary to add a high-grade oxidation unit before the biological process to improve the biodegradability of the wastewater. The comprehensive operation cost is lower than that of a simple physical and chemical method, but is much higher than that of a simple biological method, and the operation is complex.
