4.1 Bioplastic CELLATM 生物塑料 From wastewater treatment to resources recovery 从污水处理中回收资源 * How can we produce PHA我们怎样能生产PHA A well known process 一个著名的工艺: Fundamental principle of Bio P removal Use of natural hability of some bacteria to store polymers 利用细菌的自然特性存储聚合物 ? less O2 consummed, less sludge and in fine possibility to recover a polymer which is a base product for biodegradable plastic production 氧气消耗小，污泥量少，可以回收用于生产生物可降解塑料的聚合物。 Intracellular inclusions 细胞内含物 of PHA : Poly-Hydroxy-Alcanoates 聚羟基脂肪酸酯 * 4 mains steps 四个主要步骤: 1) selection of the right biomass (PAM = Polymer Accumulating Bacteria‘s) called enrichment step 筛选适合的微生物PAM，也称为富集步骤 2) production of the carbon source for the production of PHA (VFA) called fermentation step 生产制造PHA需要的碳源挥发酸，也称为发酵步骤 3) accumulation of PHA in the biomass and conditioning of the semi-product 在生物质中富集PHA，生产半成品 4) final refining of the semi-product to obtain “pure” PHA resin and further compounding to obtain a plastic according to end-user specifications 最终精炼半成品，获得纯的PHA，最终根据用户的需求生产塑料 Main steps in the wastewater to PHA process 从污水处理中提取PHA工艺的主要步骤 * A prototype aimed at the optimization of the process line and evaluation of polymer quality 构想的目的在于优化工艺路线和提升聚合物质量 OSTARA OSTARA Brussels prototypes布鲁塞尔构想 * Brussels prototypes布鲁塞尔构想 4 pilots installed on site 四个中试装置 4.2 Struvite 鸟粪石 From wastewater treatment to resources recovery 从污水处理中回收资源 * What is struvite 鸟粪石是什么? Struvite is a cristal also named MAP (1/1/1) : Magnésium Ammonium Phosphate, NH4MgPO4,6(H2O) Struvite is a fertilizer (5%N, 28%P2O5) 鸟粪石是一种肥料 6-9 months release in soil 在土壤中6-9个月缓释 Spontaneous struvite precipitation Controled struvite precipitation Package solution for large plants : OSTARA 大厂的解决方案： OSTARA * Draining on sieve 筛选 Drying 干化 Classification 分类 Storage 储存 Big bag conditionning MgCl2 + eventually NaOH * 5. 未来污水处理厂构想 加药+滤布滤池 短程除氮 水厂精确控制 滤布滤池三级处理 短程除氮 鸟粪石制作 生物塑料制作 发电并网 焚烧，磷提取 消化 热水解 发酵VFA提取  THANKS！ 谢谢！ * * * It sometimes occurs wildly in
