Abstract

The invention relates to three compound stabilizer reagents which can effectively protect various water pipelines, water containers and the relevant equipment of the water conveyance system from biodeterioration or scaling and the treatment method and the utilization of the biodeterioration. Particularly, by utilizing the three compound stabilizer reagents acting on the water conveyance system in different period respectively, the addition dosage and the time can change according to different water quality, different microorganism pollution degree and different water treatment demand, wherein each compound stabilizer reagent main component has different sterilization mechanisms and the emphases of the reagent is also different, so that serious corrosion caused by the drug resistance of the bacteria can be solved and the sulfate reducing bacteria, the saprophyte, the iron bacteria, the nitrite bacteria, the ammonium bacteria and algae in the water conveyance system can be completely killed. The compound stabilizer reagents is suitable for the control of pipeline scaling and the pipe wall biodeterioration of the oil field water injection system, the circulating water system and the central air-conditioning cooling water system.

Description

technical field [0001] The invention relates to the fields of water treatment and metal anticorrosion, in particular to a method for killing or inhibiting the growth of harmful microorganisms and algae in a water delivery system, preventing and eliminating various inorganic salt scales and film scales on the walls of water delivery pipes and vessels, and achieving The treatment method for preventing and controlling microbial corrosion and the use of three compound prescription pharmaceutical products. Background technique [0002] Sulfate-reducing bacteria (SRB) is a general term for a class of bacteria that can reduce sulfate ions to divalent sulfide ions under certain conditions, and then form a by-product hydrogen sulfide. With the deepening of people's research on it, it is harmful The depth and breadth are more and more known: in addition to corroding equipment, it can also deteriorate water quality, increase water viscosity, destroy oil layers, block pipelines and form...
