Sludge dominated by facultative anaerobic bacteria that produce organic acids and generate acidic and neutral odors, and sludge that produces basic decomposition products and is characterized by basic odors. In order to deodorize sludge with a noticeable increase in the #II bacteria group, slow down the progression of deterioration and putrefaction, remove odors, and make sludge desirable including dehydration properties, we first use molded fulvic acid and metal iron powder. Add the material and supply oxygen by aeration and stirring.

The purpose of this method is to elute high-molecular fulvic acid (No. T-amount 1500 or more) and ferrous hydroxide into the raw sludge and react with organic matter to promote humification.

を落とすので、巨大複合構造物となり、腐植化が進む。Regarding the action function of low-molecular-weight fulvic acid, sulfuric acid 1.[As an additive; , is activated and collectively condenses with surrounding organic matter. Normally, the speed is too fast and it is difficult to form a huge structure, but the sugar oxides and glycoproteins that are abundant in raw sludge slow down the collective condensation rate, resulting in a huge complex structure and progressing in humification.

初期結合を阻害するためである。This is because saccharide oxides and glycoproteins + rI preferentially bind to iron ions, ferrous hydroxide, and their polymers, inhibiting their initial binding to fulvic acid.

により生成汚泥の結合部位が増加し、吸着力と脱水性が
向上する。High-molecular fulvic acid is produced by self-condensation due to the reduction of metallic iron and catalytic action during the production of metallic iron powder moldings, but after elution, it is either fulvic acid iron complex or C) ferrous hydroxide aggregate. Saccharide oxides and glycoproteins that become bound substances and are difficult to aggregate are aggregated, and the aggregates are combined to form sludge. This increases the number of bonding sites in the produced sludge, improving adsorption and dewatering performance.

v49する。The optimum pH for humification using fulvic acid described above varies depending on the amount, molecular weight, vI′iL, etc. of the sugars, sugar oxides, or sugars constituting the glycoproteins contained in the raw sludge. 5.8 to 7 in the original class. (), and to maintain this range, the acids derived from the fulvic acid moldings and the alkalis of the polished rice of the metal iron powder moldings:

原汚泥から誘導され、脱臭機能を有した液相である。Although the details of the structure of the liquid giant composite structure are unclear, it is possible to absorb and deodorize the acidic, basic, and neutral odors that are polished on the rocky mud, and the liquid itself is odorless. This is a liquid phase derived from raw sludge and has a deodorizing function.

性高酸化電位の作用によるもので・ある。The function of preventing alteration in sludge as the humus ratio progresses is due to the active oxygen (hydrogen peroxide, hydroxyl groups, etc.) generated during the condensation of polymers and fulvic acid and the persistent high oxidation potential of the sludge elements. This is due to the action of

The valent iron is more than twice that of the divalent iron (Fulvic acid is a monovalent micellar colloid, and has more active groups than the micellar colloid, and it mediates collective condensation. 11: The active groups on the surface 1 of the formed structure are bonded without losing them, but as the structure is oxidized, the structure itself is also oxidized, loses its binding strength, and becomes liberated.

の生理活性作用を主体にすることにある。In other words, the physiological activity of low molecular weight fulvic acid is 8! This method uses a liquid phase excluding the solid phase with high iron content, lowers the collective condensation ability, limits the generation of active oxygen, and keeps the oxidation potential in the optimal range. By maintaining this, we create an environment that suppresses the growth of microorganisms involved in deterioration, and make the physiologically active effects of low-molecular-weight fulvic acid the main ingredient.

It is true that by activating activated sludge bacteria that have been absorbed into microorganisms and whose physiological ability has decreased, their growth ability can be increased. This fact shows that in relation to soil, there are differences in germination, physiology, and yield of both leaf and root vegetables in terms of soil fertility of firewood land, and there are also differences in the size of fish, etc. It has been proven.
