Contaminated site in-situ remediation agent and construction method
The invention discloses a contaminated site in-situ remediation agent and a construction method. The contaminated site in-situ remediation agent comprises an oxidizing agent and a curing agent. The contaminated site in-situ remediation construction method comprises the following steps: uniformly mixing the contaminated site in-situ remediation agent with contaminated soil or an aquifer in situ; and performing in-situ remediation on the contaminated site through coupled in-situ chemical oxidation and in-situ curing processes. According to the method, in-situ chemical oxidation and in-situ curing processes are coupled, and the curing agent is used as an activating agent of the oxidizing agent, so that the dosage of the agent is reduced, the concentration of sulfate radicals in an oxidized repair area is reduced, organic pollutants adsorbed on soil or aquifer particles are cured and encapsulated, and rebound of in-situ chemical oxidation treatment of organic matters is prevented; and meanwhile, the used oxidizing agent is beneficial to curing reaction, and the addition of the curing agent can be reduced.
本发明公开了一种污染场地原位修复药剂及施工方法，污染场地原位修复药剂包括：氧化剂和固化剂；污染场地原位修复施工方法，包括：将污染场地原位修复药剂与污染土壤或含水层原位混匀；通过相耦合的原位化学氧化、原位固化工艺对污染场地进行原位修复。本发明将原位化学氧化、原位固化工艺进行耦合，以固化剂作为氧化剂的激活剂，减少药剂的用量，减少氧化后修复区域硫酸根的浓度，并实现对吸附在土壤或含水层颗粒上有机污染物的固化包封，防止原位化学氧化处理有机物的反弹；同时，所用氧化剂有利于固化反应，可以减少固化剂的投加。
