| titleOfInvention | Pretreatment facility for food waste using milling grinding, centrifugal solid-liquid separation and enzyme reaction |
| abstract | In the present invention, a combination of a hammer mill type automatic pulverizer and a centrifugal solids recovery unit and a chemical coagulation reactor are used in constructing a treatment process for independently and simultaneously recycling solids and desorption liquids generated from the remaining food wastes of various properties. It is composed of the process, and the organic solids are arbitrarily controlled and separated by the required amount, and the high concentration of liquid desorption liquid remaining therefrom is subjected to the recovery of floating scum and the enzymatic reaction of the filtrate by an independent storage tank for each step, thereby stably by anaerobic digestion. The present invention relates to a recycling facility for producing biogas. n At this time, the dehydrated solids generated can be composted, dried feed or carbonized, and the liquid stripping solution produces biogas, while the anaerobic digestion effluent is connected to the activated sludge method to ensure water quality that meets the discharge standard. The present invention relates to a facility for recycling effective food waste. n In the present invention, the desorption liquid generated during the solid-liquid separation to recycle food waste is contained in high concentrations of organic or inorganic substances, so when a high concentration of effluent is generated, a large amount of effluent is required, and thus the burden on operating costs It is a situation and it is possible to reduce the chemical requirements and simplify the mechanical configuration required for solids separation and dehydration by going through the pre-treatment process of enzymatic hydrolysis by aerobic microorganisms before chemical treatment. n In particular, any food wastes with different properties are automatically separated from foreign matters, the solids are pulverized to a solid state, and the solids separated by the solid-liquid separator are processed by a well-known process such as composting, feed and carbonization. In order to convert the final product as needed and at the same time convert high-concentration liquid materials that occupy more than 80% of the waste into biogas, which is an energy resource, the process operation to freely control the recovery ratio of solids and desorption liquids according to the final resource conversion purpose. Has the features. n To this end, a centrifugal solid-liquid separator is constructed in series with a hammer-type automatic pulverizer, and the desorbing liquid generated is collected by using a multi-stage storage tank prior to the flocculation reaction. By minimizing the amount of chemicals to reduce the amount of chemicals required to separate the solids by reducing the drug costs, it is characterized by maximizing the dehydration solids treatment efficiency and biogas recovery. n In particular, the present invention is an abnormal process in the production of biogas by anaerobic digestion by effectively removing various foreign matter contained in the liquid material and non-degradable or hardly degradable coarse solids which are extremely difficult to process by anaerobic digestion when separating the solids The anaerobic treatment process that solves the main causes that caused the operational problems, and converts the desorption liquid containing high concentrations of organic matter into biogas at the same time as the processing of solids recovery when constructing the remaining food waste recycling resources focused on the solidification of solids. The main process configuration is composed of the pretreatment device to proceed stably and with high efficiency. n The present invention can be applied to all the processes for pre-treatment for acid fermentation and composting and carbonization processes and other resources in the liquification process or sewage treatment, as well as the biogas energy treatment process, which is one of food waste recycling resources. The existing pretreatment process, which took up a lot of space and was discontinuously operated based on manpower, has been simplified, and the chemical cost, fuel and power cost that are excessively consumed in the desorption solution are reduced. n n Food waste, Recycling, Anaerobic digestion, Automatic grinding sorter, Screw decanter, Coagulation reaction, Enzyme pretreatment.
