Embodiment 1

[0027] A treatment method for ferrous fumarate wastewater, comprising the following steps:

[0028] (1) Dissolving polyacrylamide (PAM): According to the weight ratio of polyacrylamide: water = 0.5:100, in the PAM mixing tank, add 0.4 kg of polyacrylamide to 80 kg of hot water at a temperature > 70 ° C, and stir Dissolve for more than 3 hours until completely dissolved to obtain a 5‰ PAM solution;

[0029] (2) Flocculation and impurity removal: pump 8000kg of ferrous fumarate wastewater (sulfate radical content X=12.06% in ferrous fumarate wastewater) from the stock solution pool into the mixing tank I, then add 5‰ PAM solution, When the solution appears tofu flower-like suspended matter, stop adding, stir for 5 minutes, then filter through a 60-mesh vibrating sieve, and recover the filter residue;

[0030] (3) Dosing of calcium oxide: Pump the sieved waste water into the mixing tank II, and add calcium oxide for 10 minutes, the dosage of calcium oxide is M 氧化钙 = M 废水 ×X×56...

Embodiment 2

[0036] A treatment method for ferrous fumarate wastewater, comprising the following steps:

[0037] (1) Dissolving polyacrylamide (PAM): According to the weight ratio of polyacrylamide: water = 0.5:100, in the PAM mixing tank, add 0.5 kg of polyacrylamide to 100 kg of hot water at a temperature > 70 ° C, and stir Dissolve for more than 3 hours until completely dissolved to obtain a 5‰ PAM solution;

[0038] (2) Flocculation and impurity removal: pump 10,000 kg of ferrous fumarate wastewater (sulfate radical content in ferrous fumarate wastewater X=12.0%) from the stock solution pool to the mixing tank I, and then add 5‰ PAM solution, When the bean curd flower-like suspended matter appears in the solution, stop adding, stir for 8 minutes, and then filter through a 60-mesh vibrating sieve to obtain the filter residue recovery;

[0039] (3) Dosing calcium oxide: Pump the sieved waste water into the mixing tank II, add calcium oxide, it takes 13 minutes, the dosage of calcium oxi...

Embodiment 3

[0045] A treatment method for ferrous fumarate wastewater, comprising the following steps:

[0046] (1) Dissolving polyacrylamide (PAM): According to the weight ratio of polyacrylamide: water = 0.5:100, in the PAM mixing tank, add 0.75 kg of polyacrylamide to 150 kg of hot water at a temperature > 70 ° C, and stir Dissolve for more than 3 hours until completely dissolved to obtain a 5‰ PAM solution;

[0047] (2) Flocculation and impurity removal: pump 15,000 kg of ferrous fumarate wastewater (sulfate radical content in ferrous fumarate wastewater X=11.96%) from the stock solution pool to the mixing tank I, and then add 5‰ PAM solution, When the solution appears tofu flower-like suspended matter, stop adding, stir for 10 minutes, then filter through a 60-mesh vibrating sieve, and recover the filter residue;

[0048] (3) Dosing calcium oxide: Pump the sieved waste water into the mixing tank II, and add calcium oxide for 15 minutes, the dosage of calcium oxide is M 氧化钙 = M 废水 ...

Abstract

The invention relates to the technical field of sewage treatment, in particular to a method and device for treating ferrous fumarate wastewater. The method comprises the steps of (1) dissolving polyacrylamide; (2) conducting flocculating and removing impurities; (3) adding calcium oxide; (4) adding fumaric acid; (5) conducting filtering by a filter press; (6) removing calcium; (7) conducting standing and precipitating; and the like. The ferrous fumarate wastewater treatment method and the ferrous fumarate wastewater treatment device provided by the invention are used for treating ferrous fumarate wastewater, so that the wastewater can be completely recycled, waste is turned into wealth, no wastewater is discharged, and the ferrous fumarate wastewater treatment method and the ferrous fumarate wastewater treatment device are green and environment-friendly; and waste residues obtained after treatment can be recycled, and supernatant obtained after treatment is a solution rich in sodium fumarate and can be directly recycled to produce ferrous fumarate. By adopting the method disclosed by the invention, the problem that the ferrous fumarate wastewater is difficult to treat due to high COD and high salinity is solved, the problem of wastewater pollution is solved, and the method has remarkable economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment method and device for ferrous fumarate wastewater. Background technique [0002] Ferrous fumarate, also known as ferrous fumarate, has the molecular formula C 4 h 2 FeO 4 , is a reddish-brown solid powder. Ferrous fumarate, also known as ferrous fumarate, is a safe and efficient organic nutritional iron supplement, which belongs to organic acid iron (including: iron lysine, iron glycinate, iron methionine, etc.), and its organic ferrous iron content As high as 30%, ferrous fumarate is easily decomposed by ferrous fumarate after being absorbed. It does not require extra energy to enter red blood cells, does not stimulate the stomach, can increase and maintain the normal level of hemoglobin, and can be used as a nutritional supplement for a long time. Ferrous fumarate can prevent iron deficiency anemia in various animals, reduce diarrhea, improve the survi...
