The utility model provides a gas processing device can be used in volatile organic polluted soil, including gas collecting cover, the lower part of the gas collecting hood is arranged on the mixing pile, gas collecting hood set direction toward the ground, the gas collecting hood connected activated carbon tank inlet, canister outlet connecting fan machine. The air collecting hood is connected with the air inlet of the active carbon canister, and the air outlet of the activated carbon canister is connected with the draught fan through the air pipe. A manometer is arranged on the wind pipe. In the construction process of the mixing pile for building the water stopping curtain, the gas collecting cover is used for collecting the gas which is volatilized by the organic pollution of the soil in the operation range, and then discharged by the adsorption treatment of the activated carbon. The utility model can avoid the peculiar smell of the volatile gas and is directly exposed to the air, thereby reducing the risk of the surrounding environment and the influence on the on-site operation personnel and the residents nearby.
【技术实现步骤摘要】
一种可用于挥发性有机污染土壤的集气处理装置
本技术涉及挥发性有机污染土壤异味扩散防治领域,具体涉及一种可用于在挥发性有机污染土壤场地,利用建设止水帷幕的搅拌桩施工过程中的集气处理装置。
技术介绍
工业经济的快速发展也带来了许多环境污染事件,工业产品、废料、废液等的泄漏、偷排等污染事故频发,造成原厂区域内土壤受到不同程度的有机污染,而其中挥发性有机污染土壤由于其毒性大、气味刺激的特点,对现场操作人员、附近居民健康、生态环境和社会安定造成了严重威胁,挥发性有机污染土壤治理刻不容缓。随着国家对污染场地排查及治理的强度增大,在修复工程实施过程中,由于工艺设计不到位、施工环境管理措施的缺失等导致环境修复过程造成二次污染的发生,特别是挥发性有机污染场地的治理过程,污染土壤开挖和修复实施造成污染气体的逸散,对周边敏感目标造成环境风险,引起恶劣影响的群体事件发生。针对挥发性有机污染土壤治理的异味扩散防治措施有薄膜覆盖、泡沫抑制剂等,虽然异味扩散防治措施很多,但多数情况是施工完之后对作业面进行铺膜覆盖,而且在有机污染场地建设止水帷幕过程中任由异味扩散到空气,未能在施工过程中同时采取 ...
