Embodiment 1

[0023] In an embodiment of the present invention, a purification material for sewage treatment includes the following raw materials: 33 kg of vermiculite, 7 kg of manganese acetate, 3 kg of citral, 15 kg of sodium carboxymethyl cellulose, 5 kg of guar gum, and 0.5 kg of sodium fluoride.

[0024] Sodium fluoride is mixed with deionized water 8-9 times its mass to prepare a sodium fluoride solution; citral is mixed with 16 times its mass of ethanol to prepare a citral solution. Crush the vermiculite, pass it through a 100-mesh sieve, mix it with sodium fluoride solution, put it in a reaction kettle and stir it at 75°C for 1.1h, centrifuge to collect the precipitate, dry it and then calcinate it at 380°C for 2h , to obtain material A; wherein the centrifugal speed is 3000r / min, and the centrifugal time is 10min. Guar gum and citral solution were mixed, sealed and stirred at a temperature of 70° C. for 40 minutes, and the stirring speed was 150 r / min to prepare mixture B. Crush t...

Embodiment 2

[0026] In an embodiment of the present invention, a purification material for sewage treatment includes the following raw materials: 41 kg of vermiculite, 15 kg of manganese acetate, 7 kg of citral, 25 kg of sodium carboxymethyl cellulose, 9 kg of guar gum, and 1.2 kg of sodium fluoride.

[0027] Sodium fluoride is mixed with deionized water 8-9 times its mass to prepare a sodium fluoride solution; citral is mixed with 17 times its mass of ethanol to prepare a citral solution. Crush the vermiculite, pass it through a 150-mesh sieve, mix it with sodium fluoride solution, put it into the reaction kettle and stir it at 80°C for 1.3h, centrifuge to collect the precipitate, dry it and then calcinate it at 450°C for 3h , to obtain material A; wherein the centrifugal speed is 3000r / min, and the centrifugal time is 20min. Guar gum and citral solution were mixed, sealed and stirred at a temperature of 75° C. for 45 minutes, and the stirring speed was 200 r / min to prepare mixture B. Cr...

Embodiment 3

[0029] In an embodiment of the present invention, a purification material for sewage treatment includes the following raw materials: 35 kg of vermiculite, 9 kg of manganese acetate, 4 kg of citral, 18 kg of sodium carboxymethyl cellulose, 6 kg of guar gum, and 0.7 kg of sodium fluoride.

[0030] Mix sodium fluoride with 8.5 times its mass of deionized water to prepare a sodium fluoride solution; mix citral with 17 times its mass of ethanol to prepare a citral solution. Crush the vermiculite, pass it through a 120-mesh sieve, mix it with sodium fluoride solution, put it into the reaction kettle and stir it at 78°C for 1.2h, centrifuge to collect the precipitate, dry it and then calcinate it at 400°C for 3h , to obtain material A; wherein the centrifugal speed is 3000r / min, and the centrifugal time is 20min. Guar gum and citral solution were mixed, sealed and stirred at a temperature of 72° C. for 45 minutes, and the stirring speed was 200 r / min to prepare mixture B. Crush mate...

Abstract

The invention discloses a purifying material for treating sewage and a preparation process thereof. The purifying material contains the following materials in parts by weight: 33-41 parts of vermiculite, 7-15 parts of manganese acetate, 3-7 parts of citral, 15-25 parts of sodium carboxymethyl cellulose, 5-9 parts of guar gum and 0.5-1.2 parts of sodium fluoride. The preparation process comprises the following steps: crushing the vermiculite, mixing with sodium fluoride solution, heating and stirring, centrifugally separating to take precipitates, drying and calcining to obtain a material A; mixing the guar gum and citral solution, sealing, heating and stirring, then mixing with the material A, adding manganese acetate, stirring to be dry, adding the sodium carboxymethyl cellulose and deionized water, carrying out ultrasonic treatment, stirring to be dry, and calcining to obtain the purifying material. The purifying material and the preparation process disclosed by the invention have the advantages that the biochemical oxygen demand, the chemical oxygen demand, the permanganate index, the total phosphorus and the total nitrogen in a polluted water body can be obviously reduced, heavy metals and toxic substances such as fluoride, cadmium and arsenic in the water body also can be effectively reduced, the sewage treating speed is high, the effect is good, and the environment-friendly and non-toxic effects are achieved and the like, so that the purifying material and the preparation process are suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a purification material for sewage treatment and a preparation process thereof. Background technique [0002] With the rapid development of my country's economy, the scale and speed of the development and utilization of lake resources have been greatly enhanced, which has affected the natural evolution process of lakes and caused serious damage to lake ecosystems. With the rapid development of my country's social economy and urbanization process, the problem of lake water environment pollution has become increasingly prominent. A phenomenon in which a lake is polluted by the inflow of sewage. When the sewage flowing into the lake is too much and exceeds the self-purification capacity of the lake, the water quality of the lake will change, which will seriously deteriorate the lake environment, and environmental problems such as eutrophication, organic pollution, shrinkin...
