Abstract

The invention discloses a special water purifying agent for wastewater treatment, which comprises the following raw materials in parts by weight: 10-20 parts of bentonite, 15-25 parts of kaolin, 8-14 parts of modified attapulgite, 6-12 parts of aluminum hydroxide, 5-10 parts of sodium hydroxide solution, 6-11 parts of hydrochloric acid, 7-13 parts of activated fly ash, 3-7 parts of calcium carbonate, 2-5 parts of alum, 3-8 parts of yam, 5-9 parts of activated carbon, 0.2-0.6 parts of hydrogen oxide, 0.3-0.7 parts of pore-enhancing agent, 1-2 parts of dispersant, 1-2 parts of bactericide and an appropriate amount of water; wherein, the activated fly ash is mixed with ordinary fly ash and potassium fluoride homogeneous, and then placed in a high-temperature environment for roasting; the mass fraction concentration of the sodium hydroxide solution is 30%. The special water purifying agent for wastewater treatment has a scientific and reasonable formula, good purification performance, low cost and good stability, and can be used in large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of water purifiers, and in particular relates to a special water purifier for wastewater treatment and a preparation method thereof. Background technique [0002] Wastewater, especially industrial wastewater, is an important factor of water resource pollution at present. Therefore, wastewater treatment, especially industrial wastewater treatment, is an important issue that people have to solve at present. Therefore, some people use water purifiers for treatment and have achieved certain results. Effect. [0003] Aluminum and iron polymer inorganic polymer water purifiers are a new type of chemical industry researched and developed from the 1970s to the 1990s, which has played a great role in improving people's quality of life and improving the environment. There are many types of water purifiers, and the production processes are different. However, in the prior art, no oxidizing agent is added in the produ...
