Embodiment Construction
[0030] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:
[0031] as attached figure 1 Shown, a kind of biofilm reactor provided by the present invention comprises primary sedimentation degradation tank, carbon oxidation filter, nitrification aeration filter and re-sedimentation filter; Biofilm reactor in the present invention can be applicable to the treatment of biological sewage .
[0032] The primary sedimentation degradation tank contains a mud storage tank located in the middle of the primary sedimentation degradation tank. The sludge storage tank contains activated sludge. The top of the primary sedimentation degradation tank contains a sewage inlet. The bottom side wall of the mud storage tank contains a sewage outlet, and the sewage outlet includes strainer. Activated sludge can degrade large particles in sewage, and the degraded small particles enter the carbon oxidation filter through the filter sc...

The invention discloses a bio-membrane reactor which comprises a primary sedimentation tank, a carbon oxidation filter tank, a nitration aeration filter tank and a resedimentation filter tank, the primary sedimentation tank comprises a sludge storage tank located in the middle of the primary sedimentation tank, and the sludge storage tank comprises activated sludge. The carbon oxidation filter tank comprises a first filter tank positioned in the middle of the carbon oxidation filter tank, a first filler positioned in the first filter tank and a carbon oxidation biological membrane. The nitrification aeration filter tank comprises a second filter tank positioned in the middle of the nitrification aeration filter tank, a second filler positioned in the second filter tank and a nitrification biological membrane. The re-sedimentation filter tank comprises a third filter tank positioned in the middle of the re-sedimentation filter tank; and the top end and the bottom end of the third filter tank respectively comprise a filter screen. According to the bio-membrane reactor and the sewage treatment method thereof provided by the invention, the sewage treatment speed and efficiency can be effectively improved.
Description
technical field [0001] The invention relates to sewage treatment, in particular to a biofilm reactor and a method for sewage treatment thereof. Background technique [0002] In the field of sewage treatment, the traditional activated sludge method has problems such as difficult sludge settlement and easy loss. The biofilm treatment method of sewage is a kind of sewage aerobic biological treatment technology parallel to the activated sludge method. It is an efficient wastewater treatment method. Approach. Biofilm refers to all biologically active bodies and substances attached and fixed by moving media. In the process of biofilm attachment and fixation, a certain medium is needed to bear and complete the fixation. This medium becomes the biofilm carrier and also becomes the carrier filler. Filler is the habitat of biofilm, the carrier of biofilm, and also has the function of intercepting suspended matter. The biofilm method has the advantages of less sludge, no sludge bulk...
