Embodiment 1

[0083] An application method of an integrated sewage treatment device based on bamboo fiber filler, the combination method is as follows figure 2 As shown, the steps are:

[0084] (1) The sewage first enters the integrated sewage treatment device as the anaerobic pool A and the anoxic pool B in turn. This process device is not aerated, the HRT of the anaerobic pool is 2h, and the HRT of the anoxic pool is 2h;

[0085](2) The pretreated sewage enters three integrated sewage treatment devices connected in parallel as an aerobic pool C, and its HRT is 6h; Body DO is in the range of 2-3mg / L;

[0086] (3) The sewage treated by the aerobic tank is directly effluent; the process returns the sludge to the anaerobic tank through the water pump and the vent pipe, and the reflux ratio is 1:1.

[0087] In this embodiment, the relevant parameters of the integrated sewage treatment device are as follows:

[0088] The diameter of the cylindrical shell is 40cm, the ratio of diameter to he...

Embodiment 2

[0100] An integrated sewage treatment device based on bamboo fiber filler and its application method, the steps are:

[0101] (1) The sewage enters the integrated sewage treatment device, and the water intake time is 0.5h;

[0102] (2) After the water intake is completed, start the blower of the integrated sewage treatment device to enter the aeration reaction stage, so that the DO of the pool body is within the range of 2-3mg / L, and the HRT of this stage is 4h;

[0103] (3) After the aeration stage is completed, the sewage is allowed to stand still in the integrated sewage treatment device for 1 hour;

[0104] (4) After the static stage is completed, it enters the drainage stage, and the time of this stage is 0.5h.

[0105] In this embodiment, only one integrated sewage treatment device is adopted in the SBR process, and the sewage treatment is carried out through the alternation of the time sequence, so as to meet the requirement of effluent reaching the standard.

Abstract

The invention discloses a bamboo fibrous filler-based integrated sewage treatment device. The bamboo fibrous filler-based integrated sewage treatment device comprises an enclosed housing, wherein the housing is internally divided into an equipment mounting area, a sewage treatment area and a water outlet area in sequence by a first vertical partition and a second vertical partition; the equipment mounting area is used for mounting an aerator; the sewage treatment area is internally divided into a water distribution area, a filler area and an aeration area which are communicated in sequence from top to bottom by a first horizontal grid plate and a second horizontal grid plate; a water distribution device which is externally connected with a water inlet pipe is arranged in the water distribution area; the filler area is filled with a bamboo fibrous filler; an aeration device which is externally connected with the aerator is laid in the aeration area; the water outlet area is communicated with the aeration area and is provided with a water outlet pipe. The bamboo fibrous filler-based integrated sewage treatment device and an application method thereof are low in cost, low in energy consumption, difficult to block, small in floor space, simple in structure and convenient to operate and manage.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to the technical field of domestic sewage treatment and ecological restoration, in particular to an integrated sewage treatment device based on bamboo fiber filler and an application method thereof. Background technique [0002] Bamboo fiber filler is made of natural moso bamboo by simply cutting it off. The surface of the bamboo fiber is rough, easy to hang film, not easy to clog, no biological toxicity, long life, no secondary pollution, etc., suitable for sewage treatment process filler used. [0003] For example, the Chinese utility model patent document whose publication number is CN2107464U discloses a hedgehog-type filler, which is composed of an assembly rope and a bamboo pole fixed thereon. low. The Chinese invention patent document with the publication number CN1429778 discloses a carrier filler and its preparation method. Adult bamboo strands are directly inserted and fixe...
