Optimizing Hydrochars as a Hydrocarbon Remediation Amendment

零售燃料分销将柴油和汽油释放到土壤中，导致石油烃（PHC）污染。在寒冷气候的土壤中，由于冻结和地质条件的限制，PHC的自然衰减受到限制。修复这些土壤的一种方法是通过添加微生物降解污染物所需的必要营养物质来刺激土壤生物降解PHC。迫切需要在修复改性方面取得进展，以提高碳氢化合物的原位生物修复能力。碳氢化合物是一种富含碳的固体物质，有可能产生一种新的修复改进剂，它可以从土壤溶液中吸收PHC，然后，当它吸附到土壤表面时，将其捕获在最终的生物降解中。目前，烃类作为修复剂的合成和反应性还没有经过测试。该CU-I2I提案的目标是(a)优化含磷酸盐水炭的合成(b)评估其在实验室条件下作为PHC污染土壤修复材料的性能(c)在PHC污染场地进行水炭的现场规模试验(d)为研究生和大学本科生建立一个独特的学院-大学培训计划。这个方案包含了一种新颖的方法，利用学院、大学和工业专业知识来创造独特的培训体验。学生将与工业合作伙伴一起工作，并在正在进行原位修复的场地进行研究。将这些培训目标与我们的研究项目相结合，将解决行业对解释原位修复理论和应用的专业培训的需求。该CU-I2I不仅将开发一种修复技术，还将为原位修复从业者提供独特的培训渠道。

Retail fuel distribution releases diesel and gasoline into soil, resulting in petroleum hydrocarbon (PHC)contamination. In cold climate soils, natural attenuation of PHC is limited due to freezing and geologicallimitations. One way to remediate these soils is to stimulate soil organisms to degrade PHC by adding thenecessary nutrients that microbes need to degrade the contaminants. Advances in remediation amendments areurgently needed to improve in-situ biological remediation of hydrocarbons. Hydrochars, a carbon-rich solidmaterial potentially produces a new kind of remediation amendment that can sorb PHC from the soil's solutionand then, as it in term sorbs onto the soil surface, traps it in place for eventual biological degradation.Currently, the synthesis and reactivity of hydrochars as remediation amendments remains untested.The objectives of this CU-I2I proposal are to (a) optimize the synthesis of phosphate-bearing hydrochars (b)evaluate their performance as a remediation material for PHC-contaminated soils in laboratory conditions, (c)conduct field-scale trials of hydrochars on a PHC contaminated site and (d) build a unique College-Universitytraining program for graduate students and College undergraduates.This proposal contains a novel approach that leverages college, university and industrial expertise to create aunique training experience. Students will work with industrial partners and conduct research at sitesundergoing active in-situ remediation. Combining these training goals with our research project will addressesthe industry's need for professional training that explains both the theory and application of in-situ remediation.This CU-I2I will develop not only a remediation technology, but also a unique training pipeline forpractitioners of in-situ remediation.
