Problems solved by technology

However, the micro-animals in the biological predation technology are extremely sensitive to the environment, and it is difficult to attach high density to the ordinary filler, and under the impact of the water flow, the micro-animals tend to fall off from the ordinary filler, so that they cannot grow stably, and then the predation ability decreases. Fillers made of special materials are expensive and inconvenient to transport, which greatly limit the application and development of sludge biological predation technology

specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figures 1 to 5 Describe the present embodiment, the new micro-animal attachment combined packing of the present embodiment, it consists of packing frame 1, square gland 2, semicircular gland 3, carrier 4, perforation eye 5, bottom bracket 6, connecting cable 7 and support column 8 composition;

[0016] Among them, the packing frame 1 is provided with a carrier 4, the square gland 2 is arranged at the four corners of the packing frame 1 to fix the carrier 4, the semicircular gland 3 is buckled in the middle of the carrier 4, and the perforation holes 5 are distributed on the packing frame 1. The bracket 6 is located at the bottom of the carrier 4, and supports the carrier 4 in a horizontal and vertical direction; the connecting cable 7 connects the carrier 4 and the bottom bracket (6) through the perforated hole 5; the supporting column 8 is set on the connecting cable 7; the carrier 4 is a place for attaching microscopic animal...

specific Embodiment approach 2

[0017] Specific implementation mode two: combination Figures 1 to 5 This embodiment is described. The first difference between this embodiment and the specific embodiment is that the perforated holes 5 are distributed on the filler frame 1, and the number of holes is not limited. Other compositions and connection methods are the same as those in Embodiment 1.

[0018] The setting of the perforated holes 5 makes the upper and lower carriers staggered, which is beneficial to the upward transmission of oxygen at the bottom.

specific Embodiment approach 3

[0019] Specific implementation mode three: combination Figures 1 to 5 Describe this embodiment, the difference between this embodiment and the specific embodiment is: the connecting cable 7 connects the upper carrier 4 and the bottom bracket 6 with the lower carrier 4 and the bottom bracket 6 through the perforated eye 5 arranged on the filler frame 1 Its staggered distribution, other composition and connection methods are the same as those in Embodiment 1.

[0020] Specific implementation mode four: combination Figures 1 to 5 This embodiment is described. The difference between this embodiment and the specific embodiment is that the support column 8 is sleeved on the connecting cable 7 to connect the gap between the upper carrier 4 and the bottom bracket 6 and the lower carrier 4 and the bottom bracket 6 . Other compositions and connection methods are the same as those in Embodiment 1.

Abstract

The invention provides novel microfauna attachment combined packing, and relates to microfauna attachment combined packing. According to the novel microfauna attachment combined packing provided by the invention, the operation of microfauna attachment is simplified, the packing cost is reduced, the stable attachment and growth of microfauna are promoted, and the predatory efficiency and the reduction efficiency of sludge are improved. The packing is composed of a frame of the packing, square glands, semicircle glands, carriers, perforation holes, a bottom bracket, connecting cables and supporting columns. Compared with the conventional packing, the novel microfauna attachment combined packing has the advantages of low construction cost, convenient transportation and carrying, simple operation, high system stability, high biological density of the microfauna and high sludge reduction efficiency. By placing the novel microfauna attachment combined packing in a microfauna bed through replacing the conventional packing with the novel microfauna attachment combined packing, the sludge reduction effect can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of reducing sludge by utilizing the predation effect of micro animals, and in particular relates to a novel micro animal-attached composite filler. Background technique [0002] With the rapid growth of my country's population, accelerated industrialization process, and rapid economic development, the amount of sewage treatment in my country is increasing day by day. At present, urban sewage treatment plants still use the activated sludge method as the main treatment technology, and the corresponding sludge production has increased significantly. According to the "China Sludge Treatment and Disposal Market Analysis Report (2013 Edition)", to In 2015, the annual output of wet sludge (with a water content of 80%) in urban sewage treatment plants will be 33.59 million tons, or 92,000 tons of sludge per day, and the waste sludge that is not disposed of in time will cause great harm to the environment. How to fu...
