The invention discloses a process of purifying spherosin by fermentation of metarrhizzium anisopliae. The metarrhizium anisopliae fungus is purchased from the microorganism conservation center of the Chinese academy of agricultural sciences, and through fermenting and culturing to obtain mycelium which contains rich spherosin and fermented liquid, through ultrasonic and solution extracting, and treating by thin-film chromatography, D101 resin, silica column chromatography and gradient sublimation etc. technology to separate pure spherosin from the mycelium and fermented liquid. The spherosin produced by the process is white needle crystal with molecular weight of 173, fusion point 144-145 DEG C, and purity being not less than 98%. The process does not damage present plant resources, and has no problem of lacking resources. It has short production period, low cost, big productivity, high purity. Therefore, it is suitable to be industrialized, and it can promote the industrialization of R&D that adopts the spherosin as anti-tumour medicine and immunity intensifier.

The invention provides a channel seepage-guiding and non-return system, which comprises a longitudinal and transverse gridding draining body and a seepage-guiding and non-return device, wherein the longitudinal and transverse gridding draining body is arranged under the concrete seepage-proof panel of channel revetment; the grids of the longitudinal and transverse gridding draining body are filled with sand filter materials; the lower end of the longitudinal and transverse gridding draining body is connected with the seepage-guiding and non-return device; the seepage-guiding and non-return device is arranged in the groove of the bottom plate of the channel and is provided with a concrete shell; and the top of the seepage-guiding and non-return device is level with the bottom of the channel. The channel seepage-guiding and non-return system can guide and permeate the ground water to the channel, thereby reducing ground water level, increasing the stability of side slopes, preventing the seeping water from causing uplift damage to the bottom plate and the revetment of the channel, and frost boil in winter, enhancing the stability of the channel, and prolonging the service life. The channel seepage-guiding and non-return system also can prevent water in the channel from seeping and effectively increase the utilization factor of the water in the channel while guiding the ground water to the channel quickly.
