Technology for purifying life waste water for generation and reusing

Abstract

The technological process of treating domestic sewage for reuse includes the following steps: pre-treatment through adding strong oxidant in pre-treating pond, coagulation and reaction under stirring, and deposition in deposition pond for 1-2 hr; conventional physical and chemical purification; and secondary sterilizing treatment. The said process can degrade organic pollutant in domestic sewage efficiency, eliminate harmful and toxic matters and bacteria, and eliminate carcinogenic and mutagenic matters, and the treated water may be reused. The present invention is especially suitable for purifying water from swimming pool, bath room, etc.

Description

technical field [0001] The invention relates to a sewage purification, regeneration and reuse device, belonging to the technical field of sewage treatment. Background technique [0002] Since 1804, the British first used sedimentation, filtration, and technology as a centralized water treatment plant. In 1884, Americans invented coagulation, sedimentation, filtration, and chlorine disinfection technology, which has been used for 120 years. There are new discoveries and improvements in treatment, but the treatment process of domestic water basically remains the same, essentially no update and breakthrough. However, the water source to be treated has undergone great changes: the water source a hundred years ago was not polluted due to the underdevelopment of industry and agriculture. Over the past few decades, the development of modern industry, especially the rapid development of the chemical industry, the discharge of industrial wastewater, the loss of agricultural fertiliz...

AI Technical Summary

Problems solved by technology

Over the past few decades, the development of modern industry, especially the rapid development of the chemical industry, the discharge of industrial wastewater, the loss of agricultural fertilizers and pesticides, and the pollution of domestic sewage have increasingly seriously polluted water sources, making it difficult for traditional water treatment processes to ensure excellent quality. water quality

Not only can it not remove a large amount of dissolved organic pollutants in water, but also generate organic chlorides that are very harmful to human health during the chlorination process, such as: chloroform, chlorophenol, chlorobenzene, haloform and other strong carcinogens and mutagenic substances substance

However, the traditional water treatment process established for clean water sources in the past is no longer suitable for the current water treatment requirements of polluted water sources. In order to achieve safe and effective treatment of polluted water source water and ensure the water quality of domestic water, a new type of water treatment must be adapted to it.
