Technical Field
The utility model relates to a sewage treatment field, concretely relates to sewage circulation dilutes and clean system.
Background
The pig farm liquid dung is high concentration organic liquid dung and features high COD, ammonia nitrogen, TP and solid particle content and bad smell. If the water is directly discharged into the water body, the water body eutrophication can be caused, the ecological balance of the water body is damaged, and the environment is seriously influenced. The liquid manure must be treated using water treatment equipment to be discharged. However, the pollution indexes (such as ammonia nitrogen value and COD value) in the fecal water are too high and probably cannot meet the water inlet standard of the water treatment equipment in the prior art, so the fecal water must be treated by a front-stage treatment before the treatment of the water treatment equipment.
Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that separates a solvent from a solution using a pressure difference as a driving force, and is widely used in sewage treatment. The feed is pressurized on one side of the membrane to obtain permeate on the low pressure side and concentrate on the high pressure side of the membrane when the pressure exceeds its osmotic pressure. The concentrated solution needs further treatment to reach the discharge standard, and is usually electrolyzed by using a three-dimensional electrolysis technology, but the three-dimensional electrolysis needs more electric energy consumption.
