BIOX long-lasting biological oxidation promoting agent

Abstract

The invention relates to a BIOX long-lasting biological oxidation promoting agent, which is characterized by comprising the following components by mass 40%-80% of an oxidizing agent precursor, 10%-40% of a stabilizer and 1%-20% of a biological carrier. The BIOX long-lasting biological oxidation promoting agent has the characteristics of long effect time, high oxidant utilization efficiency and capability of promoting biodegradation, and compared with a traditional soil and groundwater oxidation remediation reagent, the BIOX long-lasting biological oxidation promoting agent can promote pollutant micro-biological degradation while chemical oxidation, and can improve technical and economical efficiency by synergistic effect of the chemical oxidation and micro-biological degradation.

Description

technical field [0001] The invention relates to soil and groundwater remediation technology, in particular to a medicament for remediating non-chlorinated organic polluted soil and groundwater by using oxidants and special bacteria. Background technique [0002] With the development of industrialized cities, more and more pollutants enter the soil and groundwater, but some pollutants are difficult to be biodegraded and remain in the environment for a long time. Many pollutants enter the human body through groundwater or other channels, causing serious damage to the human body It is a great threat and causes many diseases in the human body. The types of soil and groundwater pollution are not strictly divided at present. Considering the properties of pollutants, they can generally be divided into heavy metal pollution, petroleum organic pollution, volatile and semi-volatile compound pollution, and chlorinated organic pollution. , and nuclear pollution. Among them, non-chlo...

Problems solved by technology

Among them, bio-ventilation, natural degradation, and bio-composting methods based on bio-remediation have low repair costs, but due to the complex components of organic pollutants, some components are difficult to degrade, and the natural environment is harsh, the repair speed is slow and the degradation The recovery rate is low; based on physical restoration, air lift technology, heat treatment, soil replacement method, etc., the restoration speed is fast, but the restoration cost is high, the pollutants are not removed, and the burden on the landfill is increased.

The advanced oxidation technology based on the chemical remediation site is a new technology developed in recent years and has attracted attention at home and abroad. It can degrade a large number of organic pollutants non-selectively, but it has poor oxidation pertinence, and it is often difficult to further completely oxidize and decompose the oxidized intermediate products.
