Problems solved by technology

[0006] With the development of the surfactant industry, the biodegradability of most surfactants has been greatly improved, but the daily chemical wastewater containing a high concentration of petroleum is slow in anaerobic degradation and the reactor volume is too large, which limits the wide application of biochemical methods. application

Embodiment Construction

[0021] The following examples of the present invention describe the methods that can effectively treat pollutants such as COD, surfactants, and petroleum in daily chemical wastewater. Embodiments of the present invention will be primarily based on biochemical methods. Biochemical method refers to the method of removing organic matter by biochemical method. It is a process in which microorganisms use organic matter in water as food, transform it into their own cells and generate energy to maintain life activities.

[0022] In the biochemical method, the membrane bioreactor can completely trap the microorganisms in the bioreactor, keep the concentration of microorganisms in the activated sludge system at a high level, and the reactor has a good response to various changes in the influent load. Excellent adaptability, impact load resistance, and stable high-quality effluent quality. Therefore, the membrane bioreactor is a better choice for the implementation of biochemical metho...

Abstract

The invention relates to treatment method and a treatment apparatus for wastewater of daily chemicals. The method comprises the following steps of introducing the wastewater of the daily chemicals into a Fenton reaction tank; treating the wastewater of the daily chemicals with a Fenton method; introducing the wastewater after the Fenton reaction into a sedimentation basin for sedimentation; introducing a supernatant in the sedimentation basin into an air floatation tank for separating oil particles and small particles from the water; introducing a lower layer solution in the air floatation tank into a membrane bioreactor to carry out treatment by using a biochemical method, wherein a front end of the membrane bioreactor is an anaerobic tank and the back end of the membrane bioreactor is an aerobic tank; and discharging effluent treated completely from the membrane bioreactor.

Description

technical field [0001] The invention relates to a treatment method for producing waste water or surfactant waste water of daily chemical products containing anionic surfactants, petroleum and anilines. Background technique [0002] In the production process of daily chemical products, because the same production line often changes the product types, a large amount of pot washing water mixed with various daily chemical products is produced, which contains high COD (chemical oxygen demand), surfactants, petroleum and aniline pollutants such as. In many samplings of the daily chemical industry, it was found that petroleum and anionic surfactants are more common, and the content of aniline is quite low or only appears in very special daily chemical industry production. [0003] At present, the "Discharge Standards for Water Pollutants in the Cosmetic Industry" has been released for soliciting opinions. It sets strict limits on pollutants such as COD, anionic surfactants, and pe...
