Embodiment Construction

[0014] The invention discloses a treatment method for applying an enzyme product to sludge reduction. The enzyme is added to the water inlet pipe of the sewage treatment system, so that the anaerobic microorganisms in the sewage are transformed into aerobic microorganisms, and CO 2 , the added enzymes generate a large amount of hydrolytic extracellular enzymes, which promote the decomposition of macromolecular organic matter in the sludge into small molecular organic matter, and release bound oxygen, which are used by various microorganisms. In this embodiment, the dosing point of the enzyme is set on the return section of the sedimentation tank, and it is only necessary to add treatment facilities in the sludge return section, and the operation is simple.

[0015] In addition, the sewage treatment system has an aeration tank and a sedimentation tank, and the water inlet pipe of the aeration tank and the water inlet pipe of the sedimentation tank can be provided with enzyme dos...

Abstract

The invention discloses a treatment method for an enzyme product applied to sludge reduction. Enzymes are added to a water inlet pipe of a sewage treatment system, so that anaerobes in sewage are converted into aerobes, and CO2 is generated; a large amount of hydrolyzed extracellular enzymes are generated through the added enzymes, and macromolecular organic matter in sludge are decomposed into micromolecular organic matter through the hydrolyzed extracellular enzymes; and linking oxygen is released, and the micromolecular organic matter is utilized by various microorganisms. According to themethod, the enzymes are adopted, and a biological cytolytic technology is utilized; and food chains in the sludge are improved, and the capture capability of protozoa to the microorganisms in the sludge is improved so that the sludge is reduced. The treatment method is applicable for endogenous respiration of activated sludge, and the generation of excess sludge can be reduced; and species of filamentous bacteria can be reduced, and the configuration cost and operation cost of a sludge treatment device are reduced.

Description

technical field [0001] The invention relates to the technology in the field of sewage treatment, in particular to a treatment method in which an enzyme product is applied to sludge reduction. Background technique [0002] Since 1970, the activated sludge method and various forms of biofilm methods have become the standard process for sewage treatment. The process consists of a series of aerobic pools, anoxic pools, and packed towers to treat organic pollutants, mainly including On the 5th, the biological oxygen demand, chemical oxygen demand, nitrogen-containing pollutants, organic nitrogen, inorganic nitrite, nitrate and total phosphorus, among which, the total phosphorus is removed by biological phosphorus removal. After the phosphorus removal bacteria absorb a large amount of phosphorus, The form of mud is discharged, and the total phosphorus is treated; the end of the process is generally equipped with a disinfection process unit to eliminate pathogenic bacteria and viru...
