Problems solved by technology

The disadvantage of the upflow anaerobic filter is that the carrier is relatively expensive. It is estimated that the price of the carrier is equivalent to the construction price of the structure; The reason for the rapid promotion
The fluidized bed uses inert carrier particles, such as activated carbon, etc. It also needs to expand or fluidize the medium particles, which requires 0.5-10 times the recirculation of the material and liquid, which increases the energy consumption during operation.
UASB requires the use of a three-phase separator, which has an expensive structure, high energy consumption, and a high concentration of anaerobic effluent

Embodiment 1

[0028] Choose bamboo branch fillers with branches and branches covered with a large number of green bamboo leaves. Place the branches of the bamboo branches towards the edge of the pool, and place the multi-branch tails in the center of the pool. Overlap and cross in several layers to make the center bulge. The water inlet parts of the pool body are arranged loosely and the water outlet parts are closely arranged. The filling rate of the filler in the anaerobic tank is 70%. After the filler was placed, each anaerobic reactor covered the bamboo branches inside with a plane net with a hole width of 5 mm, and the net cloth (such as figure 2 As shown), a nylon rope has been sewn and connected every 1M around, and bricks are fixed at the other end of each nylon rope. The bricks are all placed on the periphery of the bamboo branch. Float in the water, take up the net cover and tighten the nylon rope, so that the packing is completely covered, so as to prevent the packing from floa...

Embodiment 2

[0033] Selecting length is 1 meter, and diameter is 2 centimetres, has branch, and the bamboo branch of a large amount of emerald and green bamboo leaves is covered with branches, bagging with hole wide 10 centimeters of specifications bag-shaped nylon plastic mesh (such as figure 1 Shown), in a fluffy shape, tie the mouth of the bag well to prevent it from falling out, the volume of each bag is about 1M 3 , regularly (branches and twigs facing the direction of water flow) overlap each other and put them into each anaerobic reactor. According to the principle of filling first sparsely and then densely, the filling rate is 50% of the volume of each pool.

[0034] The part not described in this embodiment is the same as the prior art

Embodiment 3

[0036] Such as figure 1 As shown, the selected bamboo branches are 1.5 meters in length, 1 centimeter in diameter, have multiple branches, and the branches are covered with a large number of green and green bamboo leaves, and are packed with bag-shaped nylon plastic mesh with a hole width of 15 centimeters. It is fluffy, tie the mouth of the bag well to prevent it from falling out, and the volume of each bag is about 1M 3 , and regularly (branches and twigs facing the direction of water flow) overlap each other and put them into each anaerobic reactor. According to the filling principle of sparse before and dense after, the filling rate is 80% of the capacity of each tank. After the bagged filling is filled and placed, each anaerobic reactor covers the bamboo branches inside with a plane net with a hole width of 5 mm, and the net cloth (such as figure 2 As shown) a nylon rope is sewed and connected every 1M around, and two bricks are tied to the other end of each nylon rope....

Abstract

The stuffing suitable for anaerobic reactor is bamboo branches and leaves. The stuffing configuring mode includes filling the sorted stuffing inside pond and fixing with network, or includes bagging the sorted stuffing and filling the stuffing bags inside the pond. The stuffing of the present invention has the advantages of wide material source, low cost, less rotting and being suitable for microbe to grow. The loose fixing mode with network or bag makes the stuffing capable of float up and down to strip aged biomembrane and to cut scruff.

Description

technical field [0001] The invention relates to the packing used in the anaerobic reactor and the arrangement of the packing. Background technique [0002] At present, the anaerobic tanks using filler mainly include anaerobic filter (AF) and fluidized bed. The anaerobic filter is filled with various types of solid fillers in the reactor, such as pebbles, slag, ceramic rings, plastics, etc. to treat organic wastewater. During the flow of sewage, it can contact with microorganisms suspended on the surface of the filler. Because the microorganisms are attached to the filler, they will not be lost with the overflow of the water body. Long sludge age can be obtained under short hydraulic retention time (HRT), and its cell retention time (MRT) can be as long as more than 200 days. The disadvantage of the upflow anaerobic filter is that the carrier is relatively expensive. It is estimated that the price of the carrier is equivalent to the construction price of the structure; The...
