Problems solved by technology

The physical treatment method is the simplest water treatment method, which recovers the insoluble suspended pollutants in the sewage through physical separation. The physical treatment method can only deal with some simple wastewater treatment, but the treatment is very incomplete and it is difficult to meet the discharge standard; The chemical treatment method is to use chemicals to treat pollutants, including neutralization, flocculation, redox, etc.; the biological treatment method is to dissolve pollutants in sewage through microbial metabolism, but this method requires large investment and high operating costs

Embodiment 1

[0027] Water treatment agent raw materials: zeolite 4kg, quartz 1kg, potassium feldspar 1kg, polyacrylamide 0.03kg, polyoxyethylene lauryl ether 0.08kg, surfactant 0.03kg.

[0028] Described tensio-active agent is by 0.01kg tetradecyl dimethyl benzyl ammonium chloride, 0.01kg dodecyl dimethyl benzyl ammonium chloride, 0.01kg dodecyl benzyl trimethyl chloride ammonium mixture.

[0029] Mix the zeolite, quartz, and potassium feldspar in the above parts by weight, activate them at 300°C for 30 minutes (that is, place them in an oven at 300°C for 30 minutes), grind them ultrafinely to a particle size of 5 μm, and mix them with polyacrylamide, The water treatment agent is obtained by mixing polyoxyethylene lauryl ether and a surfactant.

Embodiment 2

[0031] The water treatment agent is prepared by the raw material ratio and method of Example 1, the difference is only: the surfactant is composed of 0.015kg tetradecyl dimethyl benzyl ammonium chloride, 0.015 kg dodecyl dimethyl benzyl ammonium chloride benzyl ammonium chloride mixed.

Embodiment 3

[0033] The water treatment agent is prepared according to the raw material ratio and method of Example 1, the difference is only: the surfactant is composed of 0.015kg tetradecyldimethylbenzyl ammonium chloride, 0.015kg dodecylbenzyltri Mixture of methyl ammonium chloride.

Abstract

The invention discloses a water treatment agent and a preparation method thereof. The water treatment agent is prepared from the following raw materials in parts by weight: 35-45 parts of zeolite, 5-15 parts of quartz, 5-15 parts of potash feldspar, 0.1-0.5 part of polyacrylamide, 0.5-1.5 parts of lauryl alcohol polyoxyethylene and 0.1-0.5 part of a surface active agent. The water treatment agent disclosed by the invention is prepared from the environment-friendly raw materials, and is high in inorganic filler specific surface area, high in activity, high in dispersibility and high in adsorbability; meanwhile, the water treatment agent can play roles of demulsification, flocculation, bridging and foaming; the water treatment agent disclosed by the invention is small in using amount and high in oil removal rate, and is suitable for treatment of domestic sewage, industrial wastewater and oily sewage.

Description

technical field [0001] The invention relates to the technical field of chemical treatment of sewage, in particular to a water treatment agent and a preparation method thereof. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. With the continuous development of industrial modernization, more and more industrial wastewater is discharged, which has a great impact on the environment and human life. If the wastewater is not treated in time, it will not only directly affect the quality of air and drinking water, but also It will also indirectly affect the physical and mental health of human beings. [0003] The existing industrial and urban wastewater treatment methods include physical treatment, chemical...
