The intelligent water treatment module in fig. 8 and the core module in fig. 9 are both treatment modules such as lever type water treatment device; the intelligent water treatment system can greatly reduce the COD index and the ammonia nitrogen index of the sewage, and compared with the existing sewage treatment system, the system has the advantages of controllability, treatment efficiency and energy conservation;
after flocculating sewage and filtering the sewage by adopting a lever type water treatment device, various indexes (such as COD, ammonia nitrogen and the like) of the sewage are greatly reduced, the sewage can reach the water purification standard by the subsequent advanced technology (reverse osmosis of an advanced treatment module and electrolysis of a three-dimensional electrolysis module), the traditional biochemical technology is replaced as a whole, compared with the traditional biochemical technology, the system is uncontrollable, is greatly influenced by multiple factors such as environmental, input of digestive bacteria and the like, is completely controllable, and can realize all-weather operation and completely reliable standard discharge because the three-dimensional electrolysis technology is almost irrelevant to the environmental temperature;
reverse osmosis is carried out on the flocculated and filtered sewage through an advanced treatment module, so that the sewage is separated into a penetrating fluid and a concentrated fluid which needs further treatment; therefore, the amount of the concentrated solution to be treated of the three-dimensional electrochemical module is greatly reduced (the concentrated solution after reverse osmosis is about 10-30% of the previous sewage), so that the sewage treatment efficiency is improved, and the energy consumption is reduced; in addition, the three-dimensional electrolysis technology is particularly suitable for purifying the concentrated solution.
It will be understood that modifications and variations will be apparent to those skilled in the art from the foregoing description, and it is intended that all such modifications and variations be included within the scope of the following claims.
