Embodiment 1

[0023] Sewage treatment methods based on rod-shaped activated carbon bacteria agent, including:

[0024] (1) Preparation of bacterial agents with 10%, 50% and 90% carbon sponge content respectively;

[0025] (2) According to the ratio of 1:1:1, put the above-mentioned 10%, 50% and 90% of the carbon sponge content into the domestic sewage for treatment, and the treatment temperature is 25-30°C;

[0026] Wherein, the bacterial agent of described 10% carbon sponge content comprises:

[0027] 58 parts of starch, 28 parts of rod-shaped activated carbon, 3 parts of sodium polyacrylate, 1 part of engineering bacteria, 5 parts of tryptone, 2 parts of plant peptone, 1 part of sodium chloride, and 250 parts of water; the diameter of the rod-shaped activated carbon is 3 mm;

[0028] The sponge structure is particles with a particle size not greater than 1cm. The volume of the sponge structure accounts for 42% of the total volume. The sponge structure has 10% carbon sponge and the other ...

Embodiment 2

[0043] The comparative example of present embodiment and embodiment 1, the present embodiment adopts respectively 10% in embodiment 1, three kinds of bacterial agents of 50% and 90% carbon sponge content are respectively treated sewage, and processing method is identical with embodiment 1 , the detection results after processing are as follows:

[0044] Bacteria with 10% carbon sponge content:

[0045] After 1 hour of treatment, it was detected that the COD content of the domestic sewage was 577 mg / L, and the ammonia nitrogen content was 33.3 mg / L. After 2 hours of treatment, it was detected that the COD content of the domestic sewage was 491 mg / L, and the ammonia nitrogen content was 25.2 mg / L. After 6 hours of treatment, it was detected that the COD content of the domestic sewage was 231 mg / L, and the ammonia nitrogen content was 10.3 mg / L; after 12 hours of treatment, the COD content of the domestic sewage was detected to be 46.8 mg / L, and the ammonia nitrogen content was 0...

Abstract

The invention discloses a sewage treatment method based on rod-shaped activated carbon bactericides. The sewage treatment method based on the rod-shaped activated carbon bactericides comprises the following steps: (1) respectively preparing bactericides with different carbon sponge contents; and (2) feeding all the bactericides with the different carbon sponge contents in domestic sewage and treating the domestic sewage at the temperature of 25-30 DEG C. The bactericides comprise the following components in parts by weight: 45-65 parts of starch, 20-35 parts of rod-shaped activated carbon, 1-6 parts of sodium polyacrylate, 1-3 parts of engineering bacteria, 2-10 parts of tryptone, 1-3 parts of phytone, 1-2 parts of sodium chloride, and 200-400 parts of water, the diameter of the rod-shaped activated carbon is smaller than 5mm, the bactericides further comprise sponge structures of which the grain sizes are not greater than 1 cm, the volumes of the sponge structures account for 30-50% of the total volume of the bactericide, and the sponge structures comprise carbon sponge. The sewage treatment method based on the rod-shaped activated carbon bactericide has the advantages that chemical consumption cost is reduced, sludge quantity is reduced, water polluted substance treatment efficiency is improved, water pollution treatment effect is also improved and the like.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a sewage treatment method based on a rod-shaped activated carbon bacterial agent. Background technique [0002] As the name implies, sewage treatment agent is an additive that needs to be used in sewage treatment, such as polyacrylamide, cationic polyacrylamide, anionic polyacrylamide, nonionic, zwitterionic polyacrylamide, polyaluminum chloride, etc. in different uses It can be used as a sewage treatment agent. [0003] There are many methods of water treatment, but the existing water treatment methods include physical treatment, chemical treatment and biological treatment. The physical treatment method is the simplest water treatment method, which recovers the insoluble suspended pollutants in the sewage through physical separation. The physical treatment method can only deal with some simple wastewater treatment, but the treatment is very incomplete and it is difficult to meet the...
