Abstract
The invention discloses an evaporation wastewater pretreatment modifier which comprises the following raw materials in parts by mass: 10-15 parts of chlorine dioxide, 10-15 parts of Muyu stone mineralized spheres, 45-55 parts of poly-stalactite sodium, 10-20 parts of diatomite, 6-8 parts of silica fume, 10-20 parts of calcium aluminate, 6-8 parts of chitosan and 3-5 parts of tea saponin; the modifier for the pretreatment of the waste water is prepared by mixing raw materials of chlorine dioxide, the Muyu stone mineralized spheres, the poly-stemona sodium, the diatomite, the silica fume, the calcium aluminate, the chitosan and the tea saponin according to a certain proportion, so that the prepared modifier for the pretreatment of the waste water can quickly dissolve suspended matters, and can sterilize microorganisms contained in the waste water, thereby improving the treatment effect of the pretreatment of the waste water.
Description
Technical Field
The invention belongs to the technical field of wastewater treatment, and particularly relates to an evaporative wastewater pretreatment modifier.
Background
The wastewater treatment is to treat the wastewater by physical, chemical and biological methods, purify the wastewater, reduce pollution and achieve the purposes of wastewater recovery, reuse and full utilization of water resources. At present, in order to improve the efficiency of sewage treatment, the sewage is generally subjected to evaporation pretreatment by using a wastewater pretreatment modifier, and then the pretreated sewage is evaporated by using a sewage evaporator, so that the water quality after sewage treatment is improved.
However, since a large amount of suspended substances such as clay, protozoa, algae, bacteria and viruses exist in the wastewater, anaerobic fermentation is likely to occur after the suspended substances are precipitated, and thus the water quality is deteriorated, the conventional wastewater pretreatment modifying agent usually decomposes the suspended substances and does not have a sterilization function, and the decomposed suspended substances also contain a large amount of germs, so that the effect of wastewater pretreatment is not satisfactory, and therefore, an evaporative wastewater pretreatment modifying agent needs to be provided to solve the above problems.
Disclosure of Invention
The invention aims to provide an evaporation wastewater pretreatment modifier, which is prepared by mixing raw materials of chlorine dioxide, Muyu stone mineralized spheres, poly-stalactite sodium, diatomite, silica fume, calcium aluminate, chitosan and tea saponin according to a certain proportion, so that the prepared wastewater pretreatment modifier can quickly dissolve suspended matters, simultaneously sterilize microorganisms contained in wastewater, improve the treatment effect of wastewater pretreatment, and reduce the influence of the treated water on the evaporated organic matters by using the Muyu stone mineralized spheres, thereby being beneficial to the evaporation treatment and solving the problems in the background technology.
In order to achieve the purpose, the invention adopts the following technical scheme:
the pretreatment modifier for the evaporation wastewater comprises the following raw materials in parts by mass: 10-15 parts of chlorine dioxide, 10-15 parts of Muyu stone mineralized spheres, 45-55 parts of poly-stalactite sodium, 10-20 parts of diatomite, 6-8 parts of silica fume, 10-20 parts of calcium aluminate, 6-8 parts of chitosan and 3-5 parts of tea saponin.
Preferably, the paint comprises the following raw materials in parts by mass: 10 parts of chlorine dioxide, 10 parts of Muyu stone mineralized balls, 45 parts of Polystalactite, 10 parts of diatomite, 6 parts of silica fume, 10 parts of calcium aluminate, 6 parts of chitosan and 3 parts of tea saponin.
Preferably, the paint comprises the following raw materials in parts by mass: 12 parts of chlorine dioxide, 12 parts of Muyu stone mineralized balls, 50 parts of sodium polioenzoate, 15 parts of diatomite, 7 parts of silica fume, 15 parts of calcium aluminate, 7 parts of chitosan and 4 parts of tea saponin.
Preferably, the composition comprises the following raw materials in parts by mass: 15 parts of chlorine dioxide, 15 parts of Muyu stone mineralized balls, 55 parts of sodium polioenanthate, 20 parts of diatomite, 8 parts of silica fume, 20 parts of calcium aluminate, 8 parts of chitosan and 5 parts of tea saponin.
Preferably, the chlorine dioxide has strong adsorption penetration capacity on the cell wall of the microorganism, effectively oxidizes enzymes in the cell containing sulfhydryl groups, inhibits the synthesis of microbial proteins and destroys the microorganism, and is used for killing bacterial propagules, bacterial spores, fungi, mycobacteria and viruses.
