Problems solved by technology

However, its shortcomings are also obvious. On the one hand, due to the slow water flow between the biological fillers, the hydraulic scouring force is small; in addition, the biofilm in the reactor can only fall off by itself, and the remaining sludge is not easy to drain away. Deterioration affects the treatment effect; and the biological filler needs to be replaced regularly, and the maintenance of its structures is difficult

Abstract

The invention relates to a waste water purifying equipment. The invention provides a biological stuffing shaking bed in which biological stuffing composed of fibers attached with microorganisms easily are arranged. The shaking bed of the invention overcomes the technique defects of general wastewater treatment devices, and can realize the stable treatment effect and remove the organic matters, nitrogen, phosphorus and chroma in water, and the range of application is wide.

Description

【Technical field】 [0001] The invention belongs to the technical field of wastewater treatment. More specifically, the present invention relates to a biological filler shaking bed and its application in wastewater purification. 【Background technique】 [0002] In recent years, new sewage treatment plants have sprung up like mushrooms after rain, but the current sewage treatment technology in my country is generally relatively backward, accompanied by many problems, such as large amount of sludge, difficult follow-up treatment, high energy consumption, treatment The effect is unstable, the sewage treatment plant emits an unpleasant smell, etc. It can be seen that there are many technical problems that have not been solved in the sewage treatment plant that has been built. [0003] The contact oxidation method is a wastewater biochemical treatment method that combines the characteristics of the activated sludge method and the biofilm method. It has a wide range of applications ...
