Abstract

The invention provides a preparation method for high-efficient specialized flocculant, which comprises the following steps of weighing components according to mass, storing the components separately for standby; adding 60wt%-70wt% of clear water into a mixer, and starting stirring for 3-5 minutes at the stirring speed of 130-170 R/min; adding sodium hydroxide or sodium chloride into the mixer, and starting stirring for 18-22 minutes at the stirring speed of 130-170 R/min; adding polyacrylamide into the mixer, staring stirring with the stirring speed of 130-170 R/min, meanwhile adding the remained water in parts by mass, starting stirring for at least 20 minutes until the agents are mixed uniformly and stopping stirring. The composite flocculant is water solution of sodium hydroxide or sodium chloride and polyacrylamide; the composite stabilizer consists of the following components in parts by mass: 2500-2600 parts of clear water, 25-35 parts of polyacrylamide and 290-310 parts of sodium hydroxide or sodium chloride.

Description

technical field [0001] The invention belongs to the technical field of coagulants, and in particular relates to a preparation method of a high-efficiency special coagulant. Background technique [0002] Due to reasons such as unreasonable dosing of chemicals and large doses of chemicals in the process of oilfield sewage treatment, secondary pollution and a large amount of sludge are produced in oilfield sewage treatment, which not only causes waste of resources, but also leads to environmental pollution. In order to reduce sludge residue, and to carry out harmless treatment of a small amount of sludge, and then realize comprehensive utilization, the pollution of sludge to the environment can be greatly reduced, and green and clean production can be realized. Contents of the invention [0003] In order to solve the above-mentioned technical defects, the object of the present invention is to provide a method for preparing a high-efficiency special coagulant, which can effect...
