preparation example Construction

[0041] The preparation process of the magnetic spherical filler 5 is as follows:

[0042] Preparation of acid-modified biochar: place the biochar in hydrochloric acid or sulfuric acid with pH ≤ 4 to react, wash, and dry to obtain acid-modified biochar; the size of any one direction of the biochar is less than or equal to 0.5 cm; the The reaction time is 20-35 minutes, and the drying temperature is 50-80°C;

[0043] Preparation of mixed solution A: adding ferrous ions and ferric ions to water to obtain mixed solution A; the molar ratio of ferric ions to ferrous ions in the mixed solution A is 1.2-1.8.

[0044] Preparation of adsorbed Fe 2+ and Fe 3+ Biochar: add the acid-modified biochar into the mixed solution A, after stirring, after adsorption treatment and solid-liquid separation, the adsorption Fe 2+ and Fe 3+ of biochar; the preparation adsorbs Fe 2+ and Fe 3+ The stirring time in the biochar is 2-3 minutes, and the adsorption treatment time is 30-50 minutes;

Abstract

The invention provides a rotary filler biological membrane reactor, which comprises a reactor shell and a center shaft, wherein the center shaft is installed in the reactor shell through a supportingseat. The rotary filler biological membrane reactor also comprises a rotary filler unit and a plurality of water supply pipes, wherein a plurality of rotary filler units are evenly distributed and installed on the center shaft; each rotary filler unit comprises a round shaft and a rotary filler; a plurality of rotary fillers are evenly distributed and fixed on the round shaft; the round shaft is installed on the center shaft; each rotary filler comprises a magnetic spherical filler and a hollow cylindrical magnetic filler; the magnetic spherical filler is semi-embedded into the hollow cylindrical magnetic filler; the water supply pipes are installed on the reactor shell and are positioned in the tangent direction of the rotary filler unit; through the water flow impact of the water supplypipes, the rotary filler units drive the center shaft to rotate. According to the rotary filler biological membrane reactor, kinetic energy consumption in the operation of the biological membrane reactor can be reduced, and therefore, the problem of uneven aeration of a traditional biological membrane reactor can be solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a rotating packing biofilm reactor. Background technique [0002] With the development of industry and the improvement of people's living standards, the amount of sewage produced is increasing year by year. Sewage is mainly concentrated in sewage treatment plants, so as the main treatment place for sewage, sewage treatment plants play a vital role in the process of sewage treatment. In the current sewage treatment process, biological treatment is often used to purify sewage. The biological treatment method mainly uses the microorganisms in the water to absorb the organic matter in the water during its growth process, convert it into simple inorganic matter through its own metabolism, discharge the sludge, and purify the water body. [0003] In the biological treatment of sewage, biological contact oxidation pond and biological aerated filter are two commonly used treatm...
