A porous grog with a body composition of water, clay and combustible material. Further, an earthenware water purification filter utilizing the porous grog in the body composition of the filter. Further, an earthenware filter utilizing silver chloride treatment for water disinfection is disclosed. A water purification system incorporating said filter, said water purification system capable of removing about 99% of all particles not less than 1.0 micron is size, and removing virtually 100% of fecal coliform indicators. In other embodiments, methods of disinfecting pottery toilet liners including various open surfaces using silver chloride treatment are disclosed.

The invention discloses a distilled grain organic fertilizer and a production method of the distilled grain organic fertilizer. A fermentation material of the distilled grain organic fertilizer comprises the following components in parts by mass: 100 parts of distilled grains, 3-5 parts of straw, 1-2 parts of wood sawdust, 2-2.5 parts of quick lime and 0.2-0.3 part of a strain. The production method comprises the following steps: inoculating the fermentation material with the strain, uniformly mixing to construct a strip pile, and performing fermentation; heating the strip pile to 60-65 DEG C, and turning the pile; regulating the pile turning frequency under a principle of maintaining the temperature of the strip pile to be not more than 65 DEG C; naturally ventilating for 1-2 months after fermenting; further crushing and screening to obtain a distilled grain organic fertilizer final product. The method for producing the distilled grain organic fertilizer, disclosed by the invention, is short in fermentation time and controllable in fermentation degree; the obtained product comprises the following components in percentage by weigh: 76% of an organic matter, 4% of N, 2.18% of P2O5, 1.29% of K2O, 7.74% of total nutrients and 29% of moisture; the pH value of the product is 6.2; indicators of the mortality of roundworm eggs and the number of fecal coliforms of the product can meet the requirements of NY884.

The invention belongs to the field of medicaments, and particularly relates to oxazolidinone compounds and their uses in the preparation of antibiotics. A technical problem to be solved by the invention is to provide new oxazolidinone compounds having the structure represented by Formula I. The oxazolidinone compounds of the invention, which are new compounds obtained through numerous screening, have significant antibacterial activity against bacteria such as drug-resistant staphylococcus aureus, fecal coliform bacteria, and streptococcus pneumoniae, while exhibiting low toxicity. The invention provides new options for the development and application of antibiotics.
