It should be noted that: in the first step, the hydroxyethyl cellulose is a tasteless and nontoxic fibrous solid, is prepared from alkali cellulose and ethylene oxide through etherification reaction, and belongs to nonionic soluble cellulose ethers.
It should be noted that: in step two, sodium hydroxide has a corrosive effect on hydroxyethyl cellulose and gives off heat when dissolved or diluted with a concentrated solution.
It should be noted that: in the second step, the zeolite has ion exchange property, adsorption separation property, catalytic property, stability, chemical reactivity, reversible dehydration property, conductivity and other properties.
It should be noted that: in the third step, the calcium hydrophosphate is white crystalline powder, is easily dissolved in dilute hydrochloric acid, dilute nitric acid and acetic acid, and is slightly dissolved in water.
It should be noted that: in the fourth step, the drying time of the mixed solution in the drying box was 3 hours.
To sum up: the water pollution treating agent and the preparation method thereof enable heavy metals and granular impurities in sewage to be removed more efficiently by selecting raw materials such as diatomite, peat and the like and setting four steps of mixing, stirring, soaking, washing, heating, stirring and drying and discharging, and have biodegradability, so that the treatment efficiency of the treating agent on sewage is improved.
