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.

Embodiment 1

[0012] Embodiment 1: the steps of the present invention are as follows, one, to the sewage that enters the pretreatment tank to contain the thicker suspended matter such as various greases, detergents, at first adjust the pH value to neutrality, then add high manganese in the ratio of 8mg / L Potassium acid potassium is fully coagulated by stirring, fully reacted, and then enters the sedimentation tank connected with the pretreatment tank, and settles for 1.2 hours. 2. Carry out the conventional physical and chemical purification treatment process for the settled sewage, and the process conditions are the same as the conventional process conditions; that is, it is sent to the reaction tank by the conveyor, and the flocculant is added through the dosing device, and the medicine is controlled by the flow meter. The volume is used to form flocs in the pool, and the water and dirt are separated through the high-pressure air flotation device. The suspended impurities are removed from ...

Embodiment 2

[0013] Embodiment 2: the steps are as follows, one, to the denser sewage that contains suspended solids such as pesticides that enters the pretreatment tank, at first the pH value is adjusted to neutrality, then add potassium permanganate by 4mg / L ratio, fully mix by stirring Coagulate, react fully, and then enter the sedimentation tank connected to the pretreatment tank, settle for 1 hour, and use an ozone machine for secondary sterilization and disinfection. Other processes are the same as in Example 1.

Embodiment 3

[0014] Embodiment 3: the steps are as follows, one, the bath water that enters the pretreatment tank contains the lighter sewage such as detergent, the pH value is adjusted to neutrality at first, then adds potassium permanganate by 2mg / L ratio, by Stir to fully coagulate and fully react, then enter the sedimentation tank connected to the pretreatment tank, settle for 1 hour, and carry out secondary sterilization and disinfection through an electronic sterilizer. Other processes are the same as in Example 1.

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...
