What are the main monitoring indicators of domestic waste?

1. Domestic garbage.

Completion rate of treatment facilities: refers to the number of completed domestic waste treatment projects The number of projects that should be built in the planning within the jurisdiction; At the same time, the overall situation of the construction of domestic waste treatment facilities in various places was evaluated. Provinces, autonomous regions, municipalities directly under the Central Government, cities and counties are the assessment units.

Second, the harmless treatment rate of domestic waste: the total amount of domestic waste harmless treatment by domestic waste treatment plants accounts for the percentage of urban domestic waste removal and transportation. Provinces, autonomous regions, municipalities directly under the Central Government, cities and counties are the assessment units.

3. The operation of domestic waste treatment facilities: the total operating expenses of the urban domestic waste harmless treatment plant (including depreciation of fixed assets.

The garbage treatment plant is used as the unit of assessment.

Fourth, the domestic waste disposal fee standard, the amount of the charge to the ratio of operating expenses. Cities and counties are used as assessment units.

The monitoring indicators of domestic waste mainly include four categories:

1. Garbage composition analysis: volatile matter, fixed carbon, ash content, moisture %2, garbage ash melting point detection: deformation temperature, softening temperature, hemisphere temperature, flow temperature.

3. Detection of calorific value of garbage: low calorific value of raw garbage (kj kg), high calorific value of dry-based combustible components (kj kg), and low-level calorific value of dry-based combustible components (kj kg).

4. Garbage element detection: c(%)h(%)n(%)s (s) (%c1(%)f(%)hg(%)

a) Nissan Nissan of household garbage.

B) the classification of domestic waste.

3) Clean and tidy household garbage cans.

Fourth) whether the transportation of domestic garbage is mixed.

Types of domestic waste: kitchen waste, packaging waste, manure residue, ash, green waste, special waste, etc.

Domestic waste testing standards: GB 18485-2014, GB16889-2008

Summary. 1. Particle size classification of garbage Sieving method: arrange according to the sieve mesh, shake continuously for 15min in turn, go to the next sieve, and then weigh the mass of each particle size, and calculate the percentage of particles of each particle size.

2. Determination of starch The determination of starch can be used to identify the degree of decomposition of compost.

When analyzing the characteristics of domestic waste, what basic indicators need to be analyzed?

1. Particle size classification of garbage Sieving method: arrange according to the sieve mesh, and shake the pure continuous for 15min in turn, turn to the next sieve, and then weigh the mass of each particle size, and calculate the percentage of particles of each particle size. 2. Determination of starch The determination of starch can be used to identify the degree of decay of compost.

3. Determination of biodegradability Garbage contains a large amount of natural and synthetic organic substances, some of which are easy to biodegrade and some are difficult to biodegrade. At present, the determination of biodegradability is based on a COD test method that can make an appropriate estimate of the biodegradability of waste at room temperatures. Posture sleepiness.

4. Determination of calorific value Calorific value is an important indicator of waste incineration. The calorific value is divided into high calorific value (ho) and pre-positive low calorific value (h n). The calorific value of combustible substances in garbage is high calorific value, but in fact garbage always contains a certain amount of inert substances and water that are not combustible, when the combustion heats up, these substances want to consume heat, and the water produced by combustion at the same time volatilizes in the form of water vapor then spine gas also consumes heat back, so the actual calorific value is much lower, and this calorific value is called low calorific value.

5. Leachate analysis Leachate refers to the aqueous solution that seeps out from the contact with domestic garbage, which extracts or dissolves the substances in the composition of the garbage.

1.In the experiment of determining the moisture in soil samples by drying method, the clean aluminum box is dried in a 105 wax oven for 2h, and the weight of the aluminum box is weighed after cooling in the dryer. Add about 5g of air-dried soil sample of former jujube to the aluminum box, and weigh the total weight of the aluminum box and the air-dried soil as; Put it into the 105 baking bureau and unpack it for 12 h, and after cooling in the dryer, the total weight of the aluminum box and the drying soil is weighed.

To find the moisture content (%) of a soil sample, please list the calculation process.

It is the weight of the soil.

It is the weight of the soil after drying, and the moisture content is subtracted by its weight.

The calculation process is sent a bit.

Intact. That's the calculation.

According to the "CJJ T102-2004 Municipal Solid Waste Classification and Evaluation Standards":

The evaluation indicators of garbage classification should include awareness rate, participation rate, container configuration rate, container integrity rate, vehicle configuration rate, classification and collection rate, resource rate and end treatment rate.

First, China's domestic waste has a high water content of 00 Second, China's domestic waste has a large proportion of organic waste such as kitchen waste and catering, 00 Third, China's domestic waste is still mainly mixed collection

The characteristics of domestic garbage are mainly complex in terms of physical properties and composition, containing many harmful components and emitting peculiar odors. Monitoring should focus on controlling the impact of odor divergence on the air, the pollution of leachate to soil and groundwater, and the absorption of harmful components in garbage in surrounding plants and crops.

Answer]: a, e

The amount of municipal solid waste generated is generally per capita index, the chaotic jujube method and the growth rate method, which can be checked by two methods combined with historical data when planning. Per capita index method, according to statistics, the current per capita domestic waste production in China's cities is about about. This value varies greatly, and the main closure is affected by the specific conditions of the city.

The growth rate method, based on base year data and annual growth rate** total amount of municipal solid waste in the planning year.
