摘要： The stabilization of bio-organic sludges such as those derived from sewage, meat works or dairy works effluent, against putrefication or microbial decomposition is disclosed. The stabilization is achieved by adding a bio-organic material, such as coir fibre, straw ,flax and/or ground bark and/or a source of carbohydrate. Preferably, the final concentration of water in the product is at least 15% by weight water, with a preferred upper limit of 70% by weight water.

摘要： A process for treating effluent such as untreated biological effluent includes a primary clarifier (1) where sludge solids are settled out from a liquid sludge fraction. The sludge solids pass to a digester (2) where the sludge solids undergo anaerobic digestion to produce digested sludge and biogas. The digested sludge is dewatered and the liquid sludge fraction and the liquid component of the dewatered digested sludge is passed to an activated sludge tank (6). The resulting activated sludge solids are then concentrated by settlement, dewatered, and flocculated under alkaline and acidic conditions. The resultant acidic activated sludge solids are neutralized before and passed to a mixing and drying apparatus (5) where the solids are mixed with the digested sludge and dried using the bio-gas as a fuel.
摘要翻译：一种处理流出物（例如未处理的生物流出物）的方法，其包括初级澄清器（1），其中液态污泥中所含的固体通过来自浆液部分的沉淀而沉积。所述固体进入消化装置（2），在消化装置（2）中进行厌氧消化，从而产生消化的污泥和沼气。消化的污泥被干燥，浆液部分以及消化和干燥污泥的液体组分进入活性污泥池（6）。然后将所得的活性液体污泥固体沉淀浓缩，干燥并在碱性和酸性条件下通过絮凝沉淀。首先将得到的活性液体污泥的酸性固体中和，并将其引入混合干燥装置（5）中，在混合干燥装置中将其与消化液体污泥混合并使用沼气作为燃料进行干燥。
