技术领域technical field

本实用新型涉及一种废水处理工艺设备,尤其是涉及一种实验室废水处理工艺设备。The utility model relates to a wastewater treatment process equipment, in particular to a laboratory wastewater treatment process equipment.

背景技术Background technique

随着科学研究越来越深入、广泛,各高等院校和科研院所的试验室废水处理问题日益突出,由于实验室废水水质极为复杂且难以预测,排放周期不定,废水量亦无规律,故而实验室废水的综合处理乃至资源化回用属于世界性难题。虽然实验室废水的排放量显著少于工业废水,但鉴于其往往含有酸碱液、有毒有害三致物、重金属以及一些新生物质,污染成分复杂,且存在瞬时高污染浓度等风险,极有可能造成污染事故,因此危害性不容小视,加强实验室废水管理,对实验室废水进行有效处理乃至回用势在必行,然而当前国内外关于实验室废水有效处理技术及工艺的研究还很薄弱,尤其是我国对实验室废水排放问题关注极为不够,尚没有完善的管理规范,同时也缺乏相应的配套技术工艺,目前各实验室废水基本未作处理而直接排入市政管网,为尽快制定实验室废水排放的管理措施,急需进行实验室废水处理技术工艺的研究及设备的研制开发。With the deepening and widening of scientific research, the problem of laboratory wastewater treatment in universities and scientific research institutes has become increasingly prominent. Because the quality of laboratory wastewater is extremely complex and difficult to predict, the discharge cycle is uncertain, and the amount of wastewater is also irregular. Therefore, The comprehensive treatment and recycling of laboratory wastewater is a worldwide problem. Although the discharge of laboratory wastewater is significantly less than that of industrial wastewater, since it often contains acid and alkali, toxic and harmful substances, heavy metals and some new substances, the pollution components are complex, and there are risks such as instantaneous high pollution concentrations, it is very likely Pollution accidents are caused, so the hazards cannot be underestimated. It is imperative to strengthen the management of laboratory wastewater and effectively treat and reuse laboratory wastewater. However, the current domestic and foreign research on effective treatment technologies and processes for laboratory wastewater is still very weak. In particular, our country has not paid enough attention to the discharge of laboratory wastewater. There is no perfect management specification, and there is also a lack of corresponding supporting technologies. At present, the wastewater from various laboratories is basically discharged into the municipal pipe network without treatment. There is an urgent need for laboratory wastewater treatment technology research and equipment research and development.
