摘要： Disclosed are a production method for compost using stock farm wastewater and a compost production system. The compost production method comprises: a step in which stock farm wastewater is anaerobically digested; a step in which solids are separated from the anaerobically digested stock farm wastewater; a step in which ammonia is collected from the solid-free effluent; a step in which multi-phase membrane separation is performed to concentrate nutrient salts, humic acid and micro-inorganic matters in the effluent from which ammonia has been collected; and a step in which the resulting products, having been separated, collected and concentrated respectively by the solid separation step, the ammonia collecting step and the multi-phase membrane separation step, are dried. It is a benefit of the invention that safe, high-quality dry compost can be produced by collecting as much useful humic acid and nutrient salts as possible from the stock farm wastewater. Moreover, the dry compost thus produced can be stored and sprayed easily, and when introduced into a farmland the solids are decomposed and the nutrient salts are eluted, so the pollution of rivers and groundwater due to a temporary spill can be avoided.
摘要翻译：公开了一种使用库存废水和堆肥生产系统的堆肥生产方法。堆肥生产方法包括：将农场废水厌氧消化的步骤; 从厌氧消化的养殖场废水中分离固体的步骤; 从不含固体的流出物收集氨的步骤; 进行多相膜分离以浓缩营养盐，腐殖酸和微量无机物质的步骤，所述流出物中已收集氨; 以及将通过固体分离步骤，氨收集步骤和多相膜分离步骤分别分离，收集和浓缩的所得产物干燥的步骤。本发明的益处是可以通过从畜牧场废水中收集尽可能多的有用的腐植酸和营养盐来生产安全，优质的干堆肥。此外，由此产生的干堆肥可以容易地储存和喷洒，并且当被引入农田时固体被分解并且营养盐被洗脱，因此可以避免由于暂时溢出而污染河流和地下水。

摘要： A method of treating a biodiesel process waste water is provided to minimize blockage of a film, to be washed easily, to be maintained comfortably and to reduce drugs use amount for nitrogen, phosphorus, trace mineral, alkalinity. A method of treating a biodiesel process waste water comprises steps of: processing process waste water using anaerobic biological nutrient removal process a two phase reaction bath comprising an acid fermenter and a methane fermenter, reducing organic compound in the process waste water and producing biogas; introducing an anaerobic treatment water passing through an anaerobic treatment step to a membrane bio reactor and removing the organic compound in the anaerobic treatment water; processing the processing water passing through a biological treatment stage by a reverse osmosis process, separating alkalinity, nitrogen, phosphorus and trace mineral and returning them in the acid fermenter and the methane fermenter.
