<p>The liquid-permeable container is made known to the public in this invention. It is used in the process of producing methane from waste such as garbage to ensure continuous and stable operation. The liquid- permeable container is formed by connecting integrated walls with the bottom. The container has a number of openings for separating solids while allowing liquid to pass. Owing to the liquid-permeable container serving as a means of transport in the process of production, waste can be orderly treated in packets, thus ensuring continuous, stable and automatic operation. The production process requires much smaller methane-generating pit, thus substantially reducing the construction cost, maintaining the temperature in the methane-generating pit better, shortening the production cycle and treating larger quantities of waste. During the production process, the soluble, heavy metal-salts and other harmful, soluble substances are kept in the fermentation liquid in the pit, thus discharging less such materials, which is more conducive to the environment protection and can be widely used for disposal of urban waste , sewage, straw, the farm garbage, sewage sludge and so forth.</p> |
