Abstract

The invention discloses a wastewater treatment method which is characterized by comprising a physical treatment method, a biological treatment method and a chemical treatment method. The method disclosed by the invention can filter wastewater to direct drinking water, effectively remove harmful substances such as suspended solids, floating oil, organic matters, colloid pollutants, heavy metals and the like and realize the purpose of purifying water which cannot be realized by other methods.

Description

technical field [0001] The invention relates to the technical field of wastewater purification treatment, in particular to a wastewater treatment method. Background technique [0002] The purpose of wastewater treatment is to separate the pollutants in the wastewater in some way, or decompose them into harmless and stable substances, so that the sewage can be purified. Generally, it is necessary to prevent the infection of poisons and germs; avoid visible objects with strange smell and bad feeling, so as to meet the requirements of different purposes. [0003] The original wastewater treatment methods generally use physical treatment methods to treat wastewater, which cannot effectively remove harmful substances such as heavy metals in water. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a filter that can filter waste water into direct drinking water, can effectively remove harmful substances such as susp...
