Embodiment 1

[0037] Such as figure 1 as shown, figure 1 It is a schematic diagram of the plug-flow aerobic biological filter wastewater treatment system in Example 1. A kind of push-flow aerobic biofilter waste water treatment system of the present invention, comprises biological filtration storage part 1, biological main filter part 2, clear water storage part 3 and aeration part 4, wherein, biological filtration storage part 1 It includes a first pool body 11 and a first communication component 12 , and the first communication component 12 is connected to the first pool body 11 . The biological main filter part 2 includes a second pool body 21 and a biological filter assembly 22, the second pool body 21 communicates with the first pool body 11 through the first communication assembly 12, and the biological filter assembly 22 is arranged in the second pool body 21; A plurality of barriers 23 are arranged in the second pool body 21 , and the plurality of barriers 23 are arranged in the s...

Embodiment 2

[0054] A kind of method that adopts plug flow type aerobic biological filter wastewater treatment system of the present invention to carry out wastewater treatment comprises the following steps:

[0055] Microbial acclimatization: prepare nutrient solution, then put the nutrient solution and inoculated sludge into the biological filter module 22 in the second pool body 21, and gradually pass waste water into the second pool body 21 until the acclimation is successful;

[0056] Wastewater treatment: the waste water to be treated in the first pool body 11 is discharged to the second pool body 21 through the first connecting component 12, the microorganisms on the filter material perform biochemical treatment on the waste water to be treated, and at the same time, the filter material and the filter bag filter the waste water The first aerator 41 continues to pass through the gas through the third communication component 42 , and finally, the treated wastewater flows into the third...

Embodiment 3

[0063] The structures of the first pool body 11 , the second pool body 21 and the third pool body 31 are all rectangular parallelepiped with a length of 12m, a width of 2m and a height of 3.5m. A barrier 23 is arranged at an interval of 4 m in the second pool body 21 , and the second pool body 21 is equally divided into three sub-pool bodies. The first biological filter 221 is pebbles, and the particle size of the first biological filter 221 is between 5-10 cm. The stacking height of the first biological filter element 221 is 0.3m. The filter bag is a rectangular porous filter bag made of polyamide fiber. The filter bag is 40cm long and 30cm wide. The nominal diameter of the filter bag is about 1mm. The filter material filled in the filter bag is ceramsite with a particle size of 3-5mm and zeolite with a particle size of 4-6mm. The filter bags are placed orderly above the first biological filter element 221 with a height of 3m. Prepare simulated wastewater COD concentrati...

Abstract

The invention discloses a plug-flow aerobic biofilter wastewater treatment system which comprises a first body, a first communication assembly, a second body, a second communication assembly and a third body which communicate with each other in sequence, and further comprises a first aeration part for conveying gas to the second body through a third communication assembly. The invention also discloses a wastewater treatment method. Wastewater flows into the second body from the first body and the first communication assembly and flows step by step along multiple blocking pieces, the filter bags and the filter materials in the second body conduct biochemical treatment and filtration on wastewater, then the wastewater flows into the third body through the second communication assembly, and the wastewater in the third body meets the discharge standard. The system improves the traditional problems of large occupied area, high economic cost, low efficiency, poor energy consumption and the like. The system also has the advantages of strong treatment capacity, wide treatment range, capability of treating high-concentration, medium-concentration and low-concentration wastewater, strong load impact resistance, strong adaptability, stable effect, simplicity in operation and the like.

Description
