Embodiment 1

[0038] A method for treating domestic feces in a community, comprising the following steps:

[0039] S1: Collect the domestic feces of households within a radius of 2km into the vacuum automatic collection tank through the feed pipe, and install an ultraviolet sterilizer on the feed pipe of the vacuum automatic collection tank. The end is connected to the community feces concentration pool, and the feces are disinfected with ultraviolet light before the feces enter the community feces concentration pool;

[0040] S2: Add deodorant and flocculant to the vacuum automatic collection tank, deodorize and flocculate the feces for the first time, and then enter the feces concentration pool of the community;

[0041] S3: Transport the feces in the feces concentration pool of the community to the feces treatment station, perform secondary deodorization, preliminary degradation, and heating and fermentation of the feces. The heating temperature is 70°C to complete the sterilization;

...

Embodiment 2

[0048] The difference from Example 1 is:

[0049] The deodorant raw material comprises the following components by weight: 38 parts of activated carbon, 14 parts of fluorinated activated carbon, 28 parts of boric acid, 23 parts of calcium oxide, 33 parts of dimethyl carbonate, 22 parts of didecyldimethylammonium chloride, 24 parts of taste-masking additives.

[0050] in:

[0051] The carbon to fluorine ratio of fluorinated activated carbon is 1.15.

[0052] The taste-masking additive comprises the following components in parts by weight: 20 parts of methyl salicylate, 24 parts of citric acid and 26 parts of peppermint. Embodiment three:

Embodiment 3

[0053] The difference from Example 1 is:

[0054] The deodorant raw material comprises the following components by weight: 42 parts of activated carbon, 16 parts of fluorinated activated carbon, 33 parts of boric acid, 25 parts of calcium oxide, 36 parts of dimethyl carbonate, 28 parts of didecyldimethylammonium chloride, 27 parts of taste-masking additives.

[0055] in:

[0056] The carbon to fluorine ratio of fluorinated activated carbon is 1.2.

[0057] The taste-masking additive comprises the following components in parts by weight: 26 parts of methyl salicylate, 30 parts of citric acid and 36 parts of peppermint.

Abstract

The invention relates to a community life excrement treatment method, relates to the field of excrement treatment, aims at solving the problem that excrement pollutes the environment, and comprises the following steps that S1, collecting excrement into a collection container on site; s2, carrying out primary deodorization and flocculation on the excrement in the collection container; s3, conveying the excrement in the collection container to an excrement treatment station, and performing secondary deodorization, primary degradation and heating fermentation on the excrement to complete sterilization; and s4, carrying out dehydration fermentation on the sterilized excrement, wherein biogas obtained by fermentation is used for power generation, the dewatered excrement residues are used for preparing an organic fertilizer, and the dehydrated water is used for preparing a liquid organic fertilizer. Excrement can be treated and recycled, the influence of excrement on the environment is effectively reduced, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The present application relates to the field of excrement treatment, in particular to a method for treating domestic excrement in a community. Background technique [0002] With the development of society, the urban population density is getting higher and higher, and the treatment of urban domestic waste has become an international problem. [0003] The main components of urban life feces are cellulose, undigested protein, amino acids, indole, hydrogen sulfide, butyrate sulfate, phosphate, chloride, and ash substances equivalent to 5%. There are three main causes of feces odor. Major substances: sulfides, amides, fatty compounds; sulfides: ethanethiol, dimethyl sulfide, diethyl sulfide, hydrogen sulfide; amides: methylamine, ethylamine trimethylamine, Amines, fatty compounds, butylenes, butyric acid, acetone acrolein. In addition, feces also contain a large number of pathogens and parasite eggs. [0004] In view of the above-mentioned related techn...
