Embodiment 1

[0014] Composite polymer flocculant, which is prepared from elm fur powder, cactus powder, sodium carboxymethyl cellulose and polyacrylamide raw materials, the mass percentage of each raw material is: elm fur powder: 42%; cactus powder: 32% %; sodium carboxymethylcellulose: 8%; polyacrylamide: 18%.

[0015] The preparation method of above-mentioned composite polymer flocculant, such as figure 1 As shown, it includes the following steps;

[0016] 1) Preparation of raw materials: dry and pulverize elm fur, then pass through a 50-mesh sieve, and then dry to obtain elm fur powder; dry and pulverize cactus, then pass through a 50-mesh sieve, and then dry to obtain cactus powder; The mass percentage of raw materials is: elm fur powder 42%, cactus powder 32%, sodium carboxymethyl cellulose 8%, polyacrylamide 18%, select elm fur powder, cactus powder, sodium carboxymethyl cellulose and polypropylene The amide raw material is spare;

[0017] 2) Mix elm fur powder, cactus powder, sod...

Embodiment 2

[0032] Composite polymer flocculant, which is prepared from elm fur powder, cactus powder, sodium carboxymethyl cellulose and polyacrylamide raw materials, the mass percentage of each raw material is: elm fur powder: 40%; cactus powder: 30% %; sodium carboxymethylcellulose: 10%; polyacrylamide: 20%.

[0033] The preparation method of the above-mentioned composite polymer flocculant is basically the same as that of Example 1, except that the ratio of raw materials is different.

Embodiment 3

[0035] Composite polymer flocculant, which is prepared from elm fur powder, cactus powder, sodium carboxymethyl cellulose and polyacrylamide raw materials, the mass percentage of each raw material is: elm fur powder: 45%; cactus powder: 35% %; sodium carboxymethylcellulose: 5%; polyacrylamide: 15%.

[0036] The preparation method of the above-mentioned composite polymer flocculant is basically the same as that of Example 1, except that the ratio of raw materials is different.

Abstract

The invention relates to a composite type polymeric flocculant which is mainly applied to the fields such as sewage treatment, sludge thickening, paper pulp recovery, petroleum extraction, etc. The composite type polymeric flocculant is characterized by being prepared by raw materials by weight percent: 40-45% of elm bark grass powder, 30-35% of cactus powder, 5-10% of sodium carboxymethyl cellulose and 15-20% of polyacrylamide. The flocculant can be normally used at higher temperature and under the condition of wider range of pH value.

Description

technical field [0001] The invention relates to a composite polymer flocculant, which is mainly used in the fields of sewage treatment, sludge concentration, pulp recovery, oil exploitation and the like. Background technique [0002] Polymer flocculants belong to the category of organic flocculation, and its main categories are carboxymethyl, ammonium amides, and acrylic acid; at present, ammonium amides are widely used. The conventional flocculant is above 50 ℃, the product is unstable, the performance cannot be guaranteed, and it is only suitable for neutral environments. In acidic or alkaline conditions, the effect is greatly reduced. Contents of the invention [0003] The purpose of the present invention is to provide a composite polymer flocculant, which can be used normally under relatively high temperature and alkaline conditions. [0004] In order to achieve the above object, the technical solution of the present invention is: a composite polymer flocculant, which...
