Reduced iron circulation type repairing agent based on sewage treatment, and preparation method of repairing agent

Abstract

The invention discloses a reduced iron circulation type repairing agent based on sewage treatment, and a preparation method of the repairing agent, belonging to the field of sewage treatment. The reduced iron circulation type repairing agent based on sewage treatment is prepared from a green repairing agent; the green repairing agent is prepared from green extract and an iron salt solution; the green extract is water hyacinth extract, and the water hyacinth extract comprises extract of stems, leaves and roots of water hyacinths; the roots of the water hyacinths have a stronger sewage purification function; nano-zero-valent iron with better quality can be prepared by using the water hyacinth extract and the iron salt solution, so that the better reduced iron circulation type repairing agent can be formed; after the scheme is adopted, sewage can be repaired by using the green repairing agent; a certain amount of the prepared green repairing agent can be put into a natural containing shell, so that quantitative loading and quantitative releasing are realized; the reduced iron circulation type repairing agent is convenient and efficient in releasing, and is beneficial to natural preservation of the green repairing agent.

Description

technical field [0001] The invention relates to the field of sewage treatment, and more specifically relates to a reduced iron circulation repair agent based on sewage treatment and a preparation method thereof. Background technique [0002] Sewage is a general term for domestic sewage, industrial wastewater, polluted rainwater and other forms of sewage. The composition of pollutants in sewage is quite complex, and there are various technologies for controlling and treating pollutants in sewage. Different sewage water quality, water volume, water body after treatment, whether there is reuse purpose, treatment degree and other requirements all determine the adopted wastewater treatment methods are different. [0003] The purpose of sewage treatment is to use a certain method to separate the pollutants in the sewage, or transform them into harmless and non-toxic stable substances, so that the sewage can be purified. From the use of ordinary biological filters and traditional...
