Embodiment 1～5

[0058] Embodiments 1-5 provide a biofilm filler prepared from the components in parts by weight shown in Table 1. The preparation method includes the following steps:

[0059] S1. Sludge pre-oxidation:

[0060] Add the sludge, potassium peroxide, carbon nitride, and ferric sulfate to the agitator, stir and mix at a speed of 200 rpm, and react for 3 hours under the irradiation of a 400w metal halide lamp to obtain oxidized sludge;

[0061] S2. Curing and shaping:

[0062] Add the oxidized sludge obtained from metakaolin, fly ash, water glass, water and S1 to the mixer, stir and mix at a speed of 200rpm, pour the mixture into the mold, seal the mold, and store it at 55±2°C, relative humidity 95 Curing for 8 days under the condition of ±2%; after removing the formwork, wrap the outer surface with burlap, and cure for 20 days at 20±3°C and relative humidity of 90±3% to obtain biofilm filler.

[0063] The raw material component (parts by weight) of the biofilm filler of table 1 emb...

Abstract

The invention discloses a biological membrane filler for phosphorus-containing wastewater treatment as well as a preparation method and application of the biological membrane filler. The biological membrane filler for phosphorus-containing wastewater treatment is prepared from the following components: sludge, metakaolin, potassium peroxide, carbon nitride, ferric sulfate, fly ash, sodium silicate and water. According to the invention, the biological membrane filler for phosphorus-containing wastewater treatment is developed, the biological membrane filler which has excellent impact strength and provides nutrient substances for phosphorus removal bacteria is prepared from the components such as the sludge, the metakaolin, the potassium peroxide, the carbon nitride and the sodium silicate , so that the membrane culturing efficiency of a biological membrane is high, phosphorus in wastewater is effectively removed, and the biological membrane filler has a stable and efficient treatment effect on high phosphorus content or excessive trace phosphorus in the wastewater.

Description

technical field [0001] The invention relates to the technical field of water treatment, and more specifically relates to a biofilm filler for phosphorus-containing wastewater treatment and a preparation method and application thereof. Background technique [0002] In recent years, with the rapid development of the economy and the improvement of people's living standards, the treatment of urban domestic sewage has become more and more important. In particular, the effluent of some domestic sewage treatment plants and drinking water sources have exceeded the standard phenomenon of phosphorus. Phosphorus is removed efficiently. [0003] The chemical phosphorus removal method is to form insoluble phosphate precipitates by adding chemicals, and finally remove phosphorus from sewage by solid-liquid separation. The chemical phosphorus removal method has a certain effect on high-concentration phosphorus exceeding the standard, but if the phosphorus exceeds the standard in a small a...
