Design of a demonstration plant that enables low-cost recycling of fisheries industrial wastes that contain harmful heavy metals and prevents environmental pollution

在处理扇贝加工废料方面，迄今为止，我们已经建立了一种仅用弱酸洗涤含cd的中肠腺的方法。在这里，我们用弱酸对去除内收肌和外壳得到的软件进行清洗，以探讨从软件清洗到含Cd废液处理的整个过程的合理性。因此，我们建立了(a)采用简单加热装置和脱水装置相结合的方法来提高清洗件的回收率；(b)防止从总洗涤液中损失有用成分的回收条件；(c)一个包括安全处理最终废液过程的系统。

In the treatment of scallop-processing wastes, we have so far established a method for washing only the Cd-containing midgut gland by using a weak acid. Here, we used a weak acid to wash the soft parts obtained by eliminating the adductor muscle and shell in order to discuss the rationality of the total process, from washing of the soft parts to disposal of the waste fluid containing Cd. As a result, we established (a) a method for increasing the rate of recovery of washed parts by combining a simple heating unit and a dehydration unit ; (b) recovery conditions for preventing the loss of useful ingredients from the total washing fluid ; and (c) a system that included a process of safe disposal of final waste fluid.
