Problems solved by technology

[0003] At present, the commonly used treatment methods include the use of metal ion capture agents, aeration, electrolysis, etc., but their effects and functions are relatively single, and they cannot effectively remove metal ions in the water body while reducing the corrosion of water injection equipment and pipelines. Severe problem of dirt

Embodiment 1

[0012] Based on the total weight of the treatment agent, add 5% of ethylene glycol diethyl ether diamine tetraacetic acid, 20% of ethylenediamine, 5% of pentasodium diethylenetriaminepentaacetic acid, 5% of trisodium phosphate, and the balance is water. Mixing, during the addition process, the interval between the addition of each raw material is more than 5 minutes.

Embodiment 2

[0014] Based on the total weight of the treatment agent, add 0.2% of ethylene glycol diethyl ether diamine tetraacetic acid, 8% of ethylenediamine, 2% of pentasodium diethylenetriaminepentaacetic acid, 4% of trisodium phosphate, and the balance is water. Mixing, during the addition process, the interval between the addition of each raw material is more than 5 minutes.

Embodiment 3

[0016] Based on the total weight of the treatment agent, add 8% of ethylene glycol diethyl ether diamine tetraacetic acid, 40% of ethylenediamine, 8% of pentasodium diethylenetriaminepentaacetic acid, 9% of trisodium phosphate, and the balance is water. Mixing, during the addition process, the interval between the addition of each raw material is more than 5 minutes.

Abstract

The invention provides a novel sewage treatment agent which comprises the following components in percentage by weight: 0.1-10% of ethylene glycol tetraacetic acid, 1-50% of ethylene diamine, 1-15% of pentasodium diethylene triamine pentaacetate, 1-15% of phosphate and the balance of water. The invention can effectively capture multiple metallic ions in the water body, such as Ca<2+>, Mg<2+>, iron ions, zinc ions, strontium ions and the like, and has obvious corrosion inhibition effect.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a sewage treatment agent capable of removing metal ions and inhibiting corrosion and scale. Background technique [0002] The water quality of industrial water bodies is characterized by high calcium hardness and often contains Ca 2+ , Mg 2+ , iron, zinc and strontium and other metal ions, the water quality is poor, and the scaling tendency is relatively high, such as oilfield reinjection water. Oilfield reinjection water is an effective way to increase oil production, but oilfield water usually has a high salinity and contains many Ions of various components such as ferrous ions, Ca 2+ , Mg 2+ etc. Poor water quality and high water temperature often cause corrosion and scaling of water injection equipment and pipelines. Therefore, when the reinjection water is reinjected into the formation for repeated use, it is necessary to try to treat the sewage. [0003] At pres...
