How to treat water purifier wastewater

2018-04-26 22:24:43

There are many methods of wastewater treatment, and the following are several common treatment methods:


1. Recycling: Some water purifier wastewater can be reused after proper treatment. For example, wastewater can be treated twice to remove impurities and pollutants, and then filtered or disinfected again to meet certain water quality standards, which can be used for non-drinking water such as flushing and cleaning.


2. Discharge to the sewer: For some wastewater that cannot be recycled, it can be discharged into the sewer system through the channel. Before discharge, it should be ensured that the waste water does not contain harmful substances or exceed the relevant discharge standards to avoid pollution to the environment.


3. Centralized treatment: For large water purification systems or industrial production of wastewater, you can choose centralized treatment. This treatment method usually includes pretreatment, precipitation, filtration, dissolved air flotation, biological treatment and other steps to effectively remove organic matter, impurities and pollutants in the wastewater.


4. Evaporation and concentration: For high-concentration wastewater, evaporation and concentration can be used for treatment. By controlling the temperature and pressure, the water in the wastewater is evaporated, resulting in concentrated waste liquid and relatively clean water vapor.


No matter which treatment method is chosen, it needs to be evaluated and selected according to the actual situation to ensure the safety, environmental protection and economy of wastewater treatment. In addition, the rational use of water purifiers and the reduction of waste water production are also very important environmental protection measures.
