A system and method for separating nutrients, such as phosphorus and protein, from biological materials may be disclosed. Biological material, for example in the form of wet solids from raw manure, may first be separated out by a solid-liquid separator. The wet solids may then be dissolved in an acidic solution, which may be created directly or by fermentation. The resulting supernatant from the acidic treatment may then be separated and phosphorus reclaimed therefrom. The resulting precipitate from the acidic treatment may be separated from the supernatant and treated with a basic solution. The resulting supernatant following the basic treatment may then be separated and protein reclaimed therefrom. In some embodiments, the supernatant resulting from the acidic treatment may itself be alkalinized, creating a precipitate which contains phosphorus solids and a supernatant which can be separated from the phosphorus solids and used as the basic solution with which to treat the precipitate resulting from the acidic treatment. Further, the system may be used to extract phosphorus and proteins from other biological materials, such as algae or crops.

A purification apparatus and purification method of a non-metallic semiconductor material relate to the field of preparation of high-purity materials, and are especially applicable to preparation of high-purity non-metal materials, in particular to an apparatus and method for purifying a non-metallic semiconductor material by means of a metal melt. The apparatus includes a furnace body, a pressure balance valve, a crucible disposed in the middle of the lower part of the furnace body, a heating and supporting structure for the crucible, a liftable injection mechanism disposed right above the crucible, and a liftable and rotatable recovery mechanism disposed next to the liftable injection mechanism. The method is completed based on the purification apparatus, and includes: injecting the gasified non-metal material into the metal melt under a high pressure environment; reducing the ambient pressure, and collecting the bubbles volatilized from the metal melt to obtain the purified non-metal material. The technical solution proposed in the present invention can be used to effectively remove impurities in the non-metal material, especially remove elements of similar properties. The apparatus is highly integrated and easy to control, and the method is simple.
