Problems solved by technology

[0003] The existing sewage treatment mainly adopts sedimentation, filtration and other means to remove most of the pollutants in the sewage to obtain relatively clean water, but if it is to be recycled and reused, the treated water is still unsuitable. There will be a certain degree of pollutant residue to be avoided, and there will be certain hazards in reusing at this time, and the existing sewage purifiers have certain limitations and pertinence, and the effect is single, while the impurities and pollutants contained in sewage are Various, so, in order to solve the above problems, it is necessary to develop a composite sewage purifier and its preparation method

preparation example Construction

[0020] A preparation method of composite sewage purifying agent, said preparation method comprises the following steps:

[0021] (1) Take an appropriate amount of nano-silver powder, nano-zinc oxide powder, nano-titanium oxide powder, and activated carbon, and mix them evenly to obtain a mixture.

[0022] (2) Add 210-230 parts of deionized water and 10-20 parts of nano-dispersant to the mixture obtained in step (1), and mix and stir evenly at a water temperature of 25-35°C to obtain solution A.

[0023] (3) Add a certain amount of clean water into the batching tank with a stirring device, and when the stirring device is turned on, slowly and evenly sprinkle carboxymethyl cellulose into the batching tank, and keep stirring to make the carboxymethyl cellulose The base cellulose and water are completely fused until the carboxymethyl cellulose is uniformly dispersed in the water and there are no obvious large lumps, then the stirring can be stopped. After stopping the stirring, le...

Abstract

The invention discloses a composite sewage purifying agent and a preparation method thereof. The composite sewage purifying agent comprises, by mass, 50-70 parts of nano-silver powder, 35-45 parts ofzinc oxide nano-powder, 35-45 parts of titanium oxide nano-powder, 15-20 parts of activated carbon, 15-20 parts of carboxymethyl cellulose, 5-10 parts of polyacrylamide, 8-12 parts of polyaluminum chloride, 8-10 parts of polyferric sulfate, 7-12 parts of aluminum sulfate, 0.1-0.5 part of a humic acid ion exchanger and 0.3-0.5 part of potassium permanganate. The composite sewage purifying agent caneffectively sterilize and purify sewage, and has the advantages of treatment of various pollutants, strong effect and wide application range by adopting a composite preparation.

Description

technical field [0001] The invention relates to a sewage purifying agent, in particular to a composite sewage purifying agent and a preparation method thereof. Background technique [0002] Sewage treatment is to use physical, chemical and biological methods to treat sewage, purify sewage, reduce pollution, and achieve sewage recycling, reuse, and make full use of water resources. Sewage treatment and utilization are inseparable from industrial production and daily life of residents. It is also a problem to open, and at the same time, the sewage is recycled and treated before being discharged, which is also conducive to preventing environmental pollution and playing a role in protecting the environment. [0003] The existing sewage treatment mainly adopts sedimentation, filtration and other means to remove most of the pollutants in the sewage to obtain relatively clean water. However, if it is to be recycled and reused, the treated water is still not suitable. There will be...
