As a nature biosynthesis gum,xanthan gum is much more environmental friendly than chemosynthesis gum

同时，由于黄原胶是一种纯天然的生物合成胶，与其他化学合成胶相比更具有环保性。

But one creature said at last,'I am tired of clinging.

但是最后有一个生物说，'我已经受够了这种粘附的生活。

Using biological reactor, without any extra nutriments, white rot fungus was directly absorbed and fixed up on the surface of cinder which was used as the carrier of sorption. Compressed air was sent into biological reactor by one coniform room which located at the bottom of the reactor. Deinking effluent was continuously transferred from one quadrate reserving pool to the reactor by a small pump.

利用生物反应器处理脱墨废水，以煤渣作为吸附载体，将白腐菌菌丝体固定吸附在煤渣表面，底部通入压缩空气，用循环水泵将废水从贮存池连续不断地泵入反应器，在不添加任何外源营养物条件下，脱墨废水有较好的处理效果。
