Problems solved by technology

At present, the treatment of kitchen sewage is mainly based on centralized collection and landfilling of domestic waste. On the one hand, such treatment wastes recyclable resources in kitchen sewage, and on the other hand, the high oil and salt characteristics of kitchen sewage are not suitable for landfill treatment.

Embodiment 1

[0017] A treatment method for kitchen sewage, which is to add a flocculant to the kitchen sewage, and then precipitate and filter; the filter residue is crushed and deodorized, and then used to make fertilizer; The water is discharged after ultraviolet disinfection.

[0018] The flocculant is prepared from the following raw materials in parts by weight: 3 parts of sodium silicate, 5 parts of magnesium chloride, 5 parts of ethanol, 3 parts of polyacrylamide, 5 parts of titanium tetrachloride, 0.1 part of diatomaceous earth, 3 parts of aluminum sulfate, 20 parts of water, 0.1 part of hydrochloric acid. The preparation process of the flocculant is as follows: 1) mix sodium silicate and magnesium chloride in proportion, then add ethanol and stir evenly; 2) mix and pulverize polyacrylamide, titanium tetrachloride, diatomite and aluminum sulfate into powder, and then Add water and mix evenly; 3) Mix the products obtained in step 1) and step 2), while continuously adding hydrochlori...

Embodiment 2

[0022] A treatment method for kitchen sewage, which is to add a flocculant to the kitchen sewage, then precipitate and filter; the filter residue is crushed and deodorized, and then used to make fertilizer; after the filtrate is left to stand for 18 hours, the upper layer of oil is collected, and the lower layer of The water is discharged after ultraviolet disinfection.

[0023] The flocculant is prepared from the following raw materials in parts by weight: 5 parts of sodium silicate, 1 part of magnesium chloride, 8 parts of ethanol, 5 parts of polyacrylamide, 1 part of titanium tetrachloride, 0.2 parts of diatomaceous earth, 5 parts of aluminum sulfate, 10 parts of water, 0.3 parts of hydrochloric acid. The preparation process of the flocculant is as follows: 1) mix sodium silicate and magnesium chloride in proportion, then add ethanol and stir evenly; 2) mix and pulverize polyacrylamide, titanium tetrachloride, diatomite and aluminum sulfate into powder, and then Add water ...

Embodiment 3

[0027] A treatment method for kitchen sewage, which is to add a flocculant to the kitchen sewage, then precipitate and filter; the filter residue is crushed and deodorized, and then used to make fertilizer; after the filtrate is left to stand for 24 hours, the upper layer of grease is collected, and the lower layer of The water is discharged after ultraviolet disinfection.

[0028] The flocculant is prepared from the following raw materials in parts by weight: 1 part of sodium silicate, 3 parts of magnesium chloride, 10 parts of ethanol, 1 part of polyacrylamide, 3 parts of titanium tetrachloride, 0.5 parts of diatomaceous earth, 1 part of aluminum sulfate, 15 parts of water, 0.5 parts of hydrochloric acid. The preparation process of the flocculant is as follows: 1) mix sodium silicate and magnesium chloride in proportion, then add ethanol and stir evenly; 2) mix and pulverize polyacrylamide, titanium tetrachloride, diatomite and aluminum sulfate into powder, and then Add wat...

Abstract

The invention belongs to the technical field of sewage treatment and in particular relates to a kitchen sewage treatment method. The kitchen sewage treatment method comprises the following steps: after adding a flocculating agent into kitchen sewage, precipitating, and filtering; smashing and deodorizing filter residue, and preparing the filter residue into fertilizer; and carrying out standing on filtrate for 12-24 hours, then collecting grease at the upper layer, and sterilizing water at the lower layer by virtue of ultraviolet light and then discharging. The kitchen sewage treatment method provided by the invention has the advantages that the kitchen sewage is shunted and treated from a source, the problems of high water consumption, high handling capacity and high treatment cost brought about by centralized treatment are avoided, resource recycling of the grease and filter residue also can be realized, and the aim of resource recycling is realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment method for kitchen sewage. Background technique [0002] Kitchen sewage refers to the sewage formed in the process of processing and consuming food in families, restaurants, hotels, canteens, etc. The sewage often contains a large amount of leftovers, expired food, leftovers, waste and other waste. At present, the treatment of kitchen sewage is mainly based on centralized collection and landfill as domestic waste. On the one hand, such treatment wastes recyclable resources in kitchen sewage, and on the other hand, the characteristics of high oil and salt in kitchen sewage are not suitable for landfill treatment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a treatment method for kitchen sewage, which can recycle the kitchen sewage and avoid waste and environmental pollution. [0004] In order ...
