The invention relates to a calcium carbonate preparation method which comprises the following steps: preparing a bacterial culture medium, implanting bacteria for an experiment into the culture medium, placing the bacterial culture medium into a track vibrator, culturing for a certain time at a certain temperature, taking out the bacterial culture medium from the track vibrator, and removing the bacterial culture medium to obtain a used bacterial solution; preparing a calcium chloride solution A as a calcium source; the method comprises the following steps: sterilizing animal urine, centrifuging, and taking supernate B as a carbon source; adding the bacterial liquid into the A/B mixed liquid, reacting for a certain time at a certain temperature, filtering and drying to obtain a calcium carbonate product. The method is characterized in that calcium carbonate is prepared through microbial induction, and the calcium carbonate can grow and precipitate on nuclear sites on the surfaces of bacteria; animal urine is used as a carbon source to replace industrial urea to prepare calcium carbonate; the method can be applied to concrete crack repair, geotechnical engineering and slope stability, is economical, effective and eco-friendly, and has a wide application prospect.
本发明涉及一种碳酸钙制备方法，包括以下步骤：制作细菌培养基，将实验所用细菌植入培养基中，并将细菌培养基放置于轨道振动器中在一定温度下培养一定时间，从轨道振动器中取出后去掉细菌培养基，得到所用细菌溶液；配制氯化钙溶液A液作为钙源；将动物尿液进行杀菌处理后，离心取上清液B液作为碳源；取细菌液加入A/B混合液中在一定温度下反应一定时间后，过滤干燥得到碳酸钙产品。该方法的特征是：利用微生物诱导制备碳酸钙，碳酸钙可以在细菌表面的核位点生长沉淀；利用动物尿液作为碳源，代替工业尿素制备碳酸钙；可用于混凝土裂缝修复、岩土工程和边坡稳定性应用，经济有效且生态友好具有广泛的应用前景。
