Overview

Dalian's harmless treatment of garbage refers to the use of advanced processes and scientific technologies in the process of treating household waste, reducing garbage and waste emissions, and achieving the process of resource recycling and utilization. It can convert heat energy into steam, which can be used for heating, air conditioning equipment, and steam turbine power generation.

Product Details

Harmless treatment of garbage in DalianThe three methods are:

(1) Landfilling is an effective method for the disposal of a large amount of urban household waste, and it is also the final treatment method for all waste disposal process residues. Currently, direct landfill is widely used in China.

(2) Incineration is a method of placing garbage in a high-temperature furnace to fully oxidize the combustible components, and the heat generated is used for power generation and heating. The waste to energy system jointly developed by Westinghouse and O'Connor has been successful. The incinerator of this system can turn garbage with a humidity of 7% into dry solids for incineration, with an incineration efficiency of over 95%. At the same time, the high temperature on the surface of the incinerator can convert heat energy into steam, which can be used for heating, air conditioning equipment, and steam turbine power generation

(3) Pile up household waste, store and ferment it at 70 ℃, and utilize the ability of microorganisms in the waste to decompose organic matter into inorganic nutrients. After composting, household waste becomes hygienic and odorless humus. It can not only solve the problem of garbage disposal, but also achieve the goal of recycling. However, the amount of household waste compost is large, the nutrient content is low, and long-term use can easily cause soil compaction and deterioration of groundwater quality. Therefore, the scale of composting is not easy to be too large.

Harmless treatment of garbage in Dalian

1、 When livestock and poultry in the breeding farm die from diseases, the principle of "five noes and one treatment" must be adhered to: no slaughter, no trafficking, no buying and selling, no disposal, no consumption, and harmless treatment must be carried out.

2、 Each breeding farm must build a harmless disposal pond at the downwind of the farm according to the scale of breeding.

3、 When a major animal epidemic occurs in a breeding farm, in addition to harmless treatment of dead animals, animals in the same group or infected with the epidemic should also be slaughtered and treated harmlessly according to the decision of the animal epidemic prevention department.

4、 When infectious diseases occur in livestock and poultry in the breeding farm, trading and trafficking of livestock and poultry are strictly prohibited, and on-site isolation observation and treatment are carried out.

5、 The harmless treatment process must be carried out under the supervision of on-site veterinarians or higher-level epidemic prevention departments, and detailed records and records of the number, cause of death, weight, treatment methods, time, etc. of the livestock and poultry subjected to harmless treatment must be carefully kept.

6、 After harmless treatment, the enclosures, utensils, roads, etc. must be disinfected to prevent the spread of pathogens.

7、 Clear signs should be set up at the burial site. When the soil cracks or sinks, it should be filled with soil in a timely manner to prevent liquid leakage and the digging of animal carcasses by wild dogs.

8、 During the harmless treatment process and epidemic periods, personal protection should be taken to prevent the transmission of zoonotic diseases to humans.
