The invention mainly relates to a method for synthetizing fluorine-free AlPO4-34 crystals with higher crystallinity and large grain size in proper treatment conditions, wherein hydrofluoric acid is not added, common organic amine morpholine (C4H9NO) is used as template agent, the traditional hydrothermal synthesis method is adopted and a proper raw material ratio is adopted. The method comprises the following steps: mixing aluminium source, phosphorus source, water and organic template agent evenly according to a certain molar ratio in sequence, wherein the molar ratio of Al2O3 to P2O5, R(morpholine) and H2O is 1.0:0.8-1.2:2.0-4.0:40-100; stirring to age, transferring the mixture in a stainless steel reaction kettle, crystallizing at 160-190 DEG C for 3-15 days under the generated pressure; then performing shock cooling, collecting, filtering, washing, and airing naturally to obtain AlPO4-34 molecular sieve raw powder. The method of the invention is green, environmentally friendly andeconomical, and has simple implementing conditions and wide application prospect.

The invention relates to a synthetic method of chabasite, which comprises the step of: adopting traditional hydrothermal synthesis to prepare chabasite through a seed crystal guiding way under a condition of not adding an organic template agent. The method avoids using expensive template agents and also avoids environmental pollution caused by high temperature firing of the template agent in a product post-treatment process. The synthetic method of the chabasite disclosed by the invention has an important significance in terms of basic research; meanwhile, as the synthetic method is economic and environment-friendly, the synthetic method also has wide application foreground.

The invention relates to a method for cultivating saline-suitable biofilms. The method is to use high-salt environment samples as salt-suitable microbial flora under the conditions of salt concentration 1%-25%, pH 6.0-9.0, and temperature 10-40°C. source, first carry out mixed enrichment culture and then carry out film-hanging culture; in the process of film-hanging culture, first control dissolved oxygen 0.5~1.0mg / L, and then gradually increase to 1.0~2.0mg / L and 2.0~4.0mg / L, so that Halo-suitable microbial flora aggregates, attaches and grows on the surface of fillers or carriers to form biofilms. By adopting the method of the invention, a salt-suitable biofilm can be cultivated in a salt environment of 1% to 25%, and pollutants in waste water can be efficiently degraded under the condition of a salt concentration of 1% to 25%.

The invention relates to a water oxygenation and purification method combining magnetic and sound field and the device. A speed regulating motor and an oxygen collecting magnetizing wheel connected with the speed regulating motor are arranged on a frame; a power ultrasonic transducer toward the oxygen collecting magnetizing wheel is also arranged on the frame. The device is characterized in that the oxygen collecting magnetizing wheel is used for separating and collecting oxygen from air and then transferring the oxygen into water, meanwhile, the power ultrasonic transducer is used for irradiating ultrasonic wave to the oxygen collecting magnetizing wheel, thereby, the oxygen absorbed on the oxygen collecting magnetizing wheel is desorbed quickly and dissolved in the water completely to oxygenate and magnetize the water. The device has the advantages of rational design, simple structure, easy operation and high efficiency of oxygenation. The water oxygenation and purification method comprises the steps of separation and collection of oxygen from air and oxygen enrichment and magnetization of water. The method has the advantages of simple method, high efficiency of oxygenation, oxygenation of pollutant in the water and purification of water. The water oxygenation and purification method combining magnetic and sound field and the device can be used for purification of sewage, restoration of water quality for landscape and continuous preparation of oxygen enriched and magnetized water for agriculture and forestry irrigation.

The invention provides a method for synthesizing a zeolite molecular sieve with a chabasite structure. The preparation method includes the step of adding organic weak base to obtain the aluminosilicate zeolite molecular sieve with the chabasite structure without adding organic template agents or chabasite seed crystals in chabasite synthesizing reaction under hydrothermal conditions. The molar ratio of framework silicon-aluminum atoms ranges from 4 to 40, and reaction raw materials are prepared according to the molar ratio of Na2O:K2O:the organic weak base Al2O3:SiO2:H2O=(1-20):(2-30):(0.05-8.0):1:(8-80):(150-800). According to the method, the zeolite molecular sieve with the chabasite structure can be stably synthesized without the template agents, fluorinated compounds and the seed crystals.
