Abstract
A provided composite flocculating agent is prepared by compounding an inorganic polymeric flocculant and a cationic polyacrylamide flocculating agent with a weight ratio of 400-500:1-4, or compounding an inorganic polymeric flocculant and an anionic polyacrylamide flocculating agent with a weight ratio of 400-500:1-4. The beneficial effects comprise that when the two raw material reagents are compounded for using, generated flocs have large shape and compact structure and are easy to separate from water, wastewater processing effect is obviously improved and the adding amount is reduced.
Description
Technical field
The present invention relates to water treatment field, especially relate to a kind of composite flocculation agent.
Background technology
Present oilfield exploitation major part has entered tertiary phase, and in order to improve recovery ratio, chemical flooding technology is used widely.The sewage of discharging in the sewage of extraction and floor treatment, drilling well, operation process in oil reservoir is gathered together, and causes oil-displacing agent in sewage, oil, suspended substance, silt and mechanical impurity equal size high, and the purification who is known is difficult to process.
The widely used method of purification of oilfield sewage is flocculent precipitation at present, namely in water, add flocculation agent, use separately inorganic flocculating agent, exist chemical feeding quantity large, in water, generate precipitation more, easily produce a large amount of mud and scum silica frost, and medicine machine, pipeline anticorrosion had to the shortcomings such as high requirement, be difficult to meet the requirement of water treatment.
Summary of the invention
While the object of this invention is to provide a kind of compound use, the flocs unit body of generation is large and structure is closely knit, be easy to water body separate, wastewater treatment efficiency be improved significantly, and dosage reduce composite flocculation agent.
Technical scheme of the present invention is:
Composite flocculation agent, by inorganic polymer flocculant with Cationic Polyacrylamide Flocculant is compound or compound by inorganic polymer flocculant and anion-polyacrylamide flocculation agent, the ratio of the compound use of inorganic polymer flocculant and Cationic Polyacrylamide Flocculant is by weight, 400-500:1-4, the ratio of the compound use of inorganic polymer flocculant and anion-polyacrylamide flocculation agent is by weight, 400-500:1-4.
