Problems solved by technology

[0006] The object of the present invention is to provide a kind of sludge deodorant and its preparation method, which is capable of modifying diatomite by means of ultrasonic waves, making the diatomite softer by vibration, and easily forming meshes inside, which is convenient for other substances to mix with The combination of diatomaceous earth and the advantage that the mesh is also convenient for the deodorization of internal raw materials solves the problem that when the sludge deodorizer deodorizes sludge, microorganisms cannot quickly form a film, thereby reducing the decomposition efficiency of microorganisms. The problem that the deodorization of sludge is not complete and the effect is not obvious

Abstract

The invention discloses a sludge deodorant and a preparation method thereof. The sludge deodorant comprises the following components in parts by weight: 35-50 parts of diatomaceous earth, 10-15 partsof tung oil, 5-10 parts of colloidal alumina, 20-30 parts of activated carbon, 5-10 parts of polypropylene diester, 15-20 parts of ferric chloride, 20-30 parts of aromatics, 5-10 parts of matrine, 5-15 parts of black poplar, 10-15 parts of mountain black locust, 20-35 parts of an accelerant, and 2-3 parts of a dispersing agent. According to the invention, the diatomaceous earth is modified by adopting an ultrasonic method and is made softer by vibration; meshes are easily formed inside the diatomaceous earth, thereby facilitating mixing of other substances and the diatomaceous earth; at the same time, the meshes facilitate deodorization of internal raw materials. The colloidal alumina and the ferric chloride can absorb sewage in sludge and react to form a complex, and the complex is more convenient for the biofilm formation of microorganisms. The activated carbon has an adsorption property, so that the deodorization efficiency of the deodorant on the sludge is increased by 10-20%, andthe decomposition efficiency of the microorganisms is increased.

Description

technical field [0001] The invention relates to the technical field of deodorant preparation, in particular to a sludge deodorant and a preparation method thereof. Background technique [0002] Sludge refers to the sediment, particulate matter and floating matter produced when wastewater is treated by physical methods, chemical methods, physical chemical methods and biological methods. Including solid substances such as sediment, fiber, and animal and plant residues mixed into sewage, as well as a complex of adsorbed organic matter, metals, germs, insect eggs, etc., with high moisture content, large stacking area, and high transportation costs. The leachate is difficult to deal with, and it is easy to produce stench and breed mosquitoes and flies, thus causing serious environmental problems. [0003] At present, there are mainly chemical deodorization methods, physical deodorization methods, and biological deodorization methods to control sludge odor. Although chemical deod...
