Urban catering pigwash industrialized treatment method

Abstract

The invention relates to an urban catering pigwash industrialized treatment method which can effectively solve the problems that urban pigwash is used to comprehensively produce biodiesel raw materials and fodder raw materials and prevented from polluting the environment and wasting the resource; the technical proposal provided by the invention comprises the following steps: small and big impurities are firstly screened from the pigwash, different impurities are separated by a separation device to store separately; the mixture of the pigwash is smashed and washed by water while solid and liquid are separated by centrifugal separation to store separately; after separating solid from liquid, the separated liquid is sent to a centrifugal device to separate oil from water; the separated pigwash oil is used to prepare biodiesel raw materials, and the separated water is recycled; after separating the solid and liquid of the pigwash, the separated solid is shaped into dregs to prepare fodder raw materials, thus realizing the pigwash industrialized treatment. The invention has the advantages that a simple and advanced method is used and the pigwash comprehensive treatment and application is effectively realized, therefore the pollution of the pigwash on urban environment is prevented and the pigwash resource is fully used with enormous economic benefit and social benefit.

Description

1. Technical field [0001] The invention relates to the field of chemical industry, in particular to a method for industrialized treatment of urban catering hog water. 2. Background technology [0002] Slops (also known as slops) are produced in large quantities in urban and rural life, especially in cities. Urban swill is a practical problem that modern cities must face. With the commercialization and urbanization of cities, people's consumption and living standards have improved, and the catering industry It is more developed, but the developed food culture also brings great worries to the city. A large amount of food waste from restaurants cannot be disposed of, which puts great pressure on urban environmental protection. However, a large amount of hogwash is a great resource. The city The treatment of hogwash is a matter that benefits the country and the people, but so far there is no effective solution, which not only seriously pollutes the urban environment, but also ca...
