Abstract
The invention relates to a water treatment device, in particular to a wastewater-free reverse osmosis (RO) water treatment device and a wastewater-free RO water treatment method. The wastewater-free RO water treatment device comprises a multistage pretreatment device, a special filter tank, an RO membrane device and a first water storage tank. The multistage pretreatment device is used for carrying out primary treatment on raw water. The special filter tank is used for carrying out filtering on wastewater generated in the process of purifying the raw water to direct drinking water and enabling the wastewater to be discharged into a water purification system again to carry out recirculation. The devices are connected together through pipelines. The wastewater-free RO water treatment device and the wastewater-free RO water treatment method are used for carrying out filtering on impurities in the wastewater and impurities in a back flushing membrane through additional arrangement of the special filter tank, enable water quality to reach the standard that the wastewater is capable of being discharged into a raw water pipeline, avoid discharging of the wastewater and improve utilization rate of water resources. Through additional arrangement of a back flushing water route, loss of an RO membrane is greatly reduced and the service life of the RO membrane is prolonged. Compared with the service life of the RO membrane of a traditional water selling machine, the RO membrane of the wastewater-free RO water treatment device is longer in service cycle and less in loss, and filtering effects are better.
