Embodiment 1

[0026] Embodiment 1: a kind of circulating water bactericidal stripping agent, comprises guanidinium salt, bromide salt and water; Described guanidinium salt is polyhexamethylene guanidine; Described bromine salt is bromochlorohydantoin;

[0027] Further, according to parts by weight, it includes 20-35 parts of polyhexamethyleneguanidine and 1-15 parts of bromochlorohydantoin;

[0028] Further, according to parts by weight, it includes 25-30 parts of polyhexamethyleneguanidine and 5-10 parts of bromochlorohydantoin;

[0029] Further, according to parts by weight, it includes 28 parts of polyhexamethyleneguanidine and 7 parts of bromochlorohydantoin;

[0030] Further, the application method of the circulating water bactericidal stripping agent is used for sterilization, algae removal, and slime stripping in industrial circulating cooling water systems, industrial direct-flow water systems, sewage treatment systems, sewage reuse water systems, and oilfield water injection system...

Embodiment 2

[0039] Embodiment 2: a kind of circulating water bactericidal stripping agent, comprises guanidine salt, bromide and water; Described guanidine salt is polyhexamethylene guanidine; Described bromine salt is bromochlorohydantoin; According to parts by weight, includes There are 25-30 parts of polyhexamethyleneguanidine and 5-10 parts of bromochlorohydantoin.

[0040] The circulating water sterilizing and stripping agent is used for sterilization, algae removal and slime stripping in industrial circulating cooling water systems, industrial direct-flow water systems, sewage treatment systems, sewage reuse water systems and oil field water injection systems.

Embodiment 3

[0041] Embodiment 3: Static sterilization experiment of heterotrophic bacteria

[0042] Test method: GB / T 14643.1-2009 Determination of bacteria and algae in industrial circulating cooling water Part 1: Determination of slime-forming bacteria Plate count method (heterotrophic bacteria).

[0043] The test directly uses on-site circulating cooling water. The circulating water of the ethylene circulating water field is used. In order to control the total number of heterotrophic bacteria in the range of 105-107 / ml in the test, culture medium was added to the recovered circulating water for 2 days of enrichment.

[0044]Experimental group: the circulating water sterilizing stripping agent prepared in Example 2.

[0045] Control group: compound bactericidal stripping agent, the main component is dodecyl benzyl ammonium chloride, accounting for 90%.

[0046] The experiment is carried out according to the following steps:

[0047] (1) The algae killing steps such as vessel prepara...

Abstract

The invention discloses a circulating water sterilization stripping agent and an application method thereof. The circulating water sterilization stripping agent comprises guanidine salt, bromine salt and water. The guanidine salt is polyhexamethylene guanidine; the bromine salt is bromochlorohydantoin. The invention has the following beneficial effects: the foam-free sewage treatment agent has the characteristic of no foam, has small influence on COD of on-site circulating water due to a small addition amount, and does not cause pressure on sewage discharge; the sludge stripping agent is small in dosage, high in cost performance and free of influence on pollution discharge, and can be widely applied to sterilization, algae removal and slime stripping of circulating cooling water in petroleum, chemical engineering, oil fields, electric power and metallurgical industries.

Description

technical field [0001] The invention relates to a bactericidal stripping agent, in particular to a circulating water bactericidal stripping agent and an application method thereof. Background technique [0002] During the cooling water circulation process, it will continuously capture dust, bacteria, flying flocs, etc. in the air into the cooling water system, and the suitable temperature and PH value of the cooling water are suitable for the growth of various microorganisms, resulting in the cooling water system The number of microorganisms in the water continues to increase, causing microbial corrosion and sludge problems, greatly reducing the service life and use effect of industrial water pipes and heat exchangers, and causing huge hidden dangers to production. [0003] Some industrial enterprises will use the method of river water settlement to obtain cooling water. The dry season of the river will cause a shortage of cooling water. The river water that has not complete...
