The invention discloses a method for improving safety performance of computers on the basis of a safety sandbox, which is used for keeping a user system clear and safe. In the method, software is mounted in a safety black box by a user, and the black box runs in a system kernel model and monitors and intercepts behaviors of the application software running in the black box. If the software sends out I/O request, the safety black box receives the request and adds the same into a request queue, and an I/O request analyzer inside the safety black box extracts the request from the request queue and then analyzes and judges the request; if the request accesses the internal resources of the safety black box, the request is added into an executing queue; if the request accesses the external system resources in a read-only manner, then the request is allowed to be added into the executing queue; if the request requires modifying the external system resources, a resource image of the external system resources is generated inside the safety black box, and the I/O request is redirected to request the internal resources of the safety black box and added into the I/O request queue. The method keeps the user system clear and safe.

The invention relates to the field of grain processing, in particular to a conditioning method capable of reducing the microorganism content in wheat. The method comprises the steps of cleaning unprocessed grain, removing impurities, conditioning and powdering in a mill. The method is characterized in that wheat wetting is achieved under the vacuum condition during conditioning, and more specifically, a vacuum drying oven is adjusted to be at a normal temperature, a proper amount of wheat is obtained through weighing, tap water is added into a dampener, mixed with wheat evenly and placed in the vacuum drying oven, the vacuum degree of the vacuum drying oven is controlled to be 65%-85%, and wheat is taken out after being wetted, tempered and then placed in the mill to be powdered. According to the method, the conditioning state of wheat is changed and the microorganism content in wheat is reduced by means of the vacuum wheat wetting technology, and then the powdering quality and eating quality of wheat are improved. By means of the method, breeding of microorganisms can be inhibited, quick conditioning can be achieved, production of fungaltoxin harmful to health can be reduced, and production efficiency can be improved; furthermore, conditioning warehouse storage capacity can be saved by more than 80%, building investments can be saved greatly, and the composite cost of products can be reduced.

The invention discloses a method for producing polyaluminium sulfate from aluminum profile machining waste liquid. The method comprises the following steps: with aluminum-containing alkaline waste liquid produced in the aluminum profile machining process as a raw material, preparing solid Al(OH)3 and a NaAlO2 solution respectively, then preparing the solid Al(OH)3 into an Al2(SO4)3 solution, finally blending the NaAlO2 solution, the Al2(SO4)3 solution and a phosphoric acid solution, and digesting to obtain polyaluminium sulfate. By the method, resource utilization of the aluminum-containing alkaline waste liquid is achieved, and in the whole process, new waste liquid is not produced, so that zero pollutant emission is achieved and cleanness and safety of the production process are ensured; meanwhile, a conventional model that harmless pollutant disposal is a pure investment project is changed, the environment is protected and economic benefits are increased, so that two advantages are achieved at one stroke.

The defense system is compact and comprehensive, multiple filtering is carried out on the website accessed in login and use of the user before the user uses the network and the webpage automatically popped up, the network use safety of the user is improved, the neatness and safety of the network environment are ensured, the use effect is enhanced, and the defense system is suitable for popularization and use.

The invention relates to the field of environment-friendly toilets, an electrochemical method and a biological method are utilized to achieve zero emission and recycling of toilet sewage, scum and sediment generated in the system are collected and then automatically pressed into a mud cake through a volute filter press, and the mud cake is treated as solid waste after being dried in the air. The invention particularly relates to a recyclable sewage treatment system and process for a mobile environment-friendly toilet. According to the main principle, macromolecular chains in sewage are brokenand degraded under the electrocoagulation and electrocatalysis action of an electrocoagulation module, meanwhile, chloride ions in the water can be excited and converted into hypochlorous acid and thelike in the electrocatalysis process to thoroughly kill bacteria, viruses and microorganisms in the water, and the treated effluent can be used for flushing toilets. The system and the process are adopted for treating the toilet sewage of the field construction operation unit without the town sewage pipe network and have the advantages that water resources are saved, environmental pollution is reduced, and the system and the process are particularly suitable for treating the toilet sewage of the field construction operation unit without the town sewage pipe network; modular overall equipmentis small in occupied area and easy and convenient to maintain; compared with a technology for treating toilet sewage by a biological method, the cost is greatly reduced, and the effect is excellent.
