Problems solved by technology

However, the crushing and direct discharge of food waste can easily generate sewage and odor, breed bacteria, mosquitoes and fly, and cause disease transmission. The condensation of oil pollution will cause blockage of drain pipes, reduce the drainage capacity of urban sewers, and high oil content and other characteristics have also increased. Urban sewage treatment plants and landfill loads, but also inevitably produce secondary pollution

Embodiment

[0011] Embodiment: first put the meal waste into the press for rinsing, crushing, and pressing for 10 to 15 minutes, preferably 12 minutes, then take 1 liter of microbial strains, that is, take 0.25 liters of Bacillus licheniformis and 0.25 liters of Bacillus megaterium , 0.25 liters of Bacillus subtilis, 0.25 liters of Bacillus cereus and 80 to 120 liters of meal waste after pressing, preferably 90 liters, and then put them into a stirring box together for stirring and mixing. When the temperature is 30° to 50°, The preferred temperature is 38° (such as when the normal temperature is lower than 30°, the stirring box can be placed in a constant temperature room until the temperature in the stirring box reaches 30° to 50°, and the stirring and mixing are carried out.), and the biodegradation is carried out for 6 to 20 / hour. And the degraded meal waste (including harmless gas and residue) is discharged outside the mixing tank from the tank cover, and the preferred biodegradation ...

Abstract

The invention relates to the technical field of environmental protection, in particular to a method for treating waste after meal in source domestic garbage treatment. The method comprises that the waste after meal is placed into a presser to be cleaned, crushed and pressed, and is characterized in that microorganism strain and the pressed waste after meal are put into an agitator tank according to the proportion of 1:80-120 to be treated by biochemical reaction. The invention effectively avoids the exposed waste after meal becoming the source region of putrefying gases and the distributing center of flies in the city, improves the existing collecting method which has low collection efficiency of waste after meal, poor sanitary condition and high labor intensity, and puts an end to the infection and further diffusion of SARS and other pathogenicbacteria of communicable diseases for the public and collecting staffs which are possibly caused in the collecting and running process of waste after meal, thus protecting the environmental health and maintaining biological balance.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for treating meal waste (swill) in domestic garbage at the source. Background technique [0002] Meal waste is the most important type of food waste, and its composition is complex, which is a mixture of oil, water, fruit peels, vegetables, rice noodles, fish, meat, bones and other substances. Meal waste is mainly composed of protein, starch and animal fat, etc., and has high content of sugar, salt and oil. Traditionally, food waste is directly used as feed for pigs in my country. In recent years, in order to standardize the behavior of livestock and poultry breeding, prevent livestock and poultry diseases and residual toxic and harmful substances from harming the human body, prevent livestock and poultry breeding pollution, and promote the sustainable development of animal husbandry, the feeding of pigs with meal waste has been greatly restricted. . ...
