Treatment agent for petrochemical wastewater and preparation method of treatment agent

Abstract

The invention discloses a treatment agent for petrochemical wastewater and a preparation method of the treatment agent. The treatment agent is prepared from the following raw materials in parts by weight: 2-10 parts of methyl isothiazolinone, 4-8 parts of sucrose, 6-12 parts of melamine, 10-16 parts of bentonite, 3-8 parts of mirabilite, 2-7 parts of aluminum sulfate, 2-5 parts of sodium silicate, 10-20 parts of lithopone, 5-12 parts of rhubarb, radix scutellariae and cortex phellodendri powder, 1.5-4 parts of a rhizoma coptidis liquid, 3-9 parts of caulis trachelospermi and 0.5-3 parts of gentiana apiata. The invention further discloses the preparation method of the treatment agent. The treatment agent has the advantages of wide raw material source, simple preparation process and low production cost, and is suitable for large-scale industrial production; the components of the treatment agent draw on strong points and make up for weak points mutually and play a synergistic role, the growth environment of bacteria is destroyed, the sterilization effect is enhanced, a good sterilization effect can be realized with only a small dose, the sterilization time is long, and the use effect is good.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a petrochemical sewage treatment agent and a preparation method thereof. Background technique [0002] As one of the important energy sources, oil and natural gas account for a large proportion in the world's energy composition. Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as "industrial blood". There are oil reserves in some areas of the upper crust. The main components of oil are various alkanes, cycloalkanes, A mixture of aromatic hydrocarbons. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products, such as solutions, fertilizers, pesticides and plastics. Natural gas refers to a mixture of hydrocarbon and non-hydrocarbon gases that are naturally deposited in formations. The main purpose of natural gas is as fuel, which can produce carbon black, chemicals and liqu...

AI Technical Summary

Problems solved by technology

The composition of oilfield wastewater is complex, not only containing salts, heavy metals, suspended solids, solid particles and other components, oilfield wastewater also contains a large number of bacteria such as sulfate-reducing bacteria, iron bacteria and saprophytic bacteria, which cause corrosion to equipment and pipelines, and damage the oilfield. Safe and stable production poses a great threat

The existing sterilizers are all conventional agents, the dosage is large, the action time is short, and the drug resistance of bacteria is also increasing, which cannot meet people's expectations
