Embodiment 1

[0018] A medicament for treating refractory organic wastewater, which is composed of the following raw materials in parts by weight: 60 parts of strong alkali, 15 parts of sodium silicate, 5 parts of lithopone, 3 parts of cellulose, 4 parts of mushroom residue, and 7 parts of polyacrylamide , 2 parts of calcium oxide, 10 parts of kaolin and 4 parts of lotus root juice. The lotus root juice is obtained by washing lotus root, blanching, pulverizing, enzymatic hydrolysis and separating the juice and putting it into a homogenizer to homogenize the obtained juice. Cellulose adopts hydroxypropyl methylcellulose.

[0019] The preparation method of the medicament for the treatment of refractory organic wastewater, the specific steps are as follows:

[0020] Step 1, put sodium silicate, lithopone, cellulose, calcium oxide and kaolin into the ball mill and add ball milling beads, the mass ratio of sodium silicate, lithopone, cellulose, calcium oxide and kaolin to ball milling beads 2:9...

Embodiment 2

[0025] A medicament for treating refractory organic wastewater, consisting of the following raw materials in parts by weight: 70 parts of strong alkali, 18 parts of sodium silicate, 7 parts of lithopone, 4.5 parts of cellulose, 5 parts of mushroom residue, and 9 parts of polyacrylamide , 5 parts of calcium oxide, 13 parts of kaolin and 6 parts of lotus root juice. The lotus root juice adopts lotus root cleaning, blanching, pulverization, enzymatic hydrolysis and separation to obtain the juice and put it into a homogenizer to homogenize the obtained juice. The strong base uses sodium hydroxide.

[0026] The preparation method of the medicament for the treatment of refractory organic wastewater, the specific steps are as follows:

[0027] Step 1, put sodium silicate, lithopone, cellulose, calcium oxide and kaolin into the ball mill and add ball milling beads, the mass ratio of sodium silicate, lithopone, cellulose, calcium oxide and kaolin to ball milling beads 1:4, ball milled...

Embodiment 3

[0032] A medicament for treating refractory organic wastewater, consisting of the following raw materials in parts by weight: 105 parts of strong alkali, 22 parts of sodium silicate, 9 parts of lithopone, 5 parts of cellulose, 6 parts of mushroom residue, and 11 parts of polyacrylamide , 6 parts of calcium oxide, 15 parts of kaolin and 7 parts of lotus root juice. The lotus root juice adopts lotus root cleaning, blanching, pulverization, enzymatic hydrolysis and separation to obtain the juice and put it into a homogenizer to homogenize the obtained juice. The cellulose is a mixture of hydroxypropylmethylcellulose and carboxymethylcellulose. Potassium hydroxide is used as strong base.

[0033] The preparation method of the medicament for the treatment of refractory organic wastewater, the specific steps are as follows:

[0034] Step 1, put sodium silicate, lithopone, cellulose, calcium oxide and kaolin into the ball mill and add ball milling beads, the mass ratio of sodium sil...

Abstract

The invention discloses an agent for treating refractory organic wastewater. The agent is composed of the following raw materials in parts by weight: 60-120 parts of strong base, 15-28 parts of sodium silicate, 5-12 parts of lithopone, 3-6 parts of cellulose, 4-7 parts of mushroom residues, 7-15 parts of polyacrylamide, 2-8 parts of calcium oxide, 10-18 parts of kaolin and 4-10 parts of lotus root juice. The invention further discloses a preparation method of the agent. According to the agent disclosed by the invention, the cost of the agent is reduced, the treatment effect is improved, and the agent is simple in preparation process, convenient in source of raw materials, high in wastewater treatment efficiency, excellent in water purification effect, high in flocculating velocity, less in produced sludge and convenient to use, is particularly suitable for treatment of mixed discharged organic wastewater in industries such as printing and dyeing, foods and the like, and has excellent social benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a medicament for treating refractory organic wastewater. Background technique [0002] Sewage includes urban sewage and industrial sewage. Sewage must be treated before it can be discharged, otherwise it will pollute water resources. Flocculants are mainly used in the field of sewage treatment, which can reduce the sensory indicators such as turbidity and color of raw water. The removal of a variety of high molecular organics, some heavy metals and radioactive substances by flocculants can be used as an independent treatment system, or combined with other treatment unit processes, as pretreatment, intermediate treatment and final treatment, and can also be used for The thickening process before sludge dewatering improves the dewatering performance of sludge. [0003] In recent years, the development of composite flocculants has become a hot spot. The composite flocculant can ov...
