The municipal solid waste treatment plant developed by the municipal solid waste treatment plant is a comprehensive treatment,and the treatment process adopts the combined anaerobic fermentation process of urban organic solid waste.The design and disposal capacity of domestic waste is single line 300t/d,fecal 135t/d and sludge 30t/d.
The main construction contents include waste and feces,sludge treatment workshop,anaerobic fermentation system,biogas collection and power generation system,fertilizer plant,water treatment facilities,plastic and combustible recycling system,boiler room,office and living facilities.
The main processing systems include:pre sorting system,anaerobic fermentation system,biogas collection and power generation system and fertilizer system,sewage treatment system,odor collection and treatment system,fecal and sludge treatment system,plastic and flammable recycler incineration treatment system,and electrical and control systems.
Two.Detailed description of the process
Three.Introduction of waste treatment process
The waste treatment technology is integrated into the municipal solid waste,such as waste and sewage sludge,and the combined anaerobic fermentation process is adopted to combine the organic matter,feces and sludge in the garbage effectively,and the fermentation process is improved to the maximum limit.Gas production.It ensures the comprehensive treatment of domestic waste,feces,sludge and so on.It does not cause two pollution.It has high efficiency of energy recovery and investment,and can effectively solve the problem of organic solid waste pollution in urban areas with small construction and operation costs.
The whole process includes two parts:pretreatment process and resource recovery process.The pretreatment process consists of three kinds of materials,such as uniform feed,artificial sorting of large part interfering,broken bag,artificial separation chamber separation,and mechanical sieves to separate 80x110mm particles and above material,80~30mm material and less than 30mm.After the magnetic selection,the wind selection and the artificial selection,the plastic products,paper,metal,rubber products,waste shoes and knitted fabrics are sorted out and collected to realize the reuse of waste materials.The fruits and vegetables are sent to the water for crushing,and the rest of the gravel is sent to the landfill for sanitary landfill.The recycling process is used to recycle the classified plastics;cotton goods,rubber products and waste shoes,wood and paper are collected as fuel;metal collection and takeaway;organic matter,such as melon,fruit,vegetable and kitchen waste,for anaerobic fermentation of biogas,after purification of biogas as boiler fuel or power generation,and biogas residue as organic fertilizer The waste water is used as liquid fertilizer,and the waste water is used in the process of production.The glass,stone and other harmless debris are sent to the landfill,so that the waste is reduced and harmless.
The waste treatment project can not only realize the reuse of all the recyclable resources in the garbage,but also process the organic matter into the new organic fertilizer which can replace the chemical fertilizer.It has the characteristics of harmless treatment,high yield of resource treatment,good product quality,high added value of the product and so on.It can promote the waste treatment industry.Development has a positive role.
Control of noise reduction
Industrial noise reduction works are divided into plant noise control,single workshop noise control and single equipment noise control.The noise control of factory area is mainly treated with three levels of noise.First,sound insulation is used in the noise source equipment,the sound absorbing material is adopted in the chamber wall panel,the device body is added to the damping device and the pipe connection adopts flexible connection.Secondly,the sound absorption plate is laid on the inner wall of the workshop,the top suspension sound absorption ball and the window use sound insulation window;finally,the window is used for sound insulation window.Make sound absorption walls in the factory.

Scope of application:noise control of single equipment is suitable for all high noise large mechanical equipment.
Noise control in workshops is suitable for densely populated urban areas,industrial areas and high noise pollution equipment and workshops.
Noise control in factories is suitable for large chemical plants and power plants.
Dedusting and noise reducing and grinding room
The equipment is mainly used for grinding the non machined surface of castings and mechanical parts;the grinding room can effectively suck out the dust produced by the equator except for grinding.The dust can be directly discharged to the workshop after the dust removal equipment is treated,and no pipe is needed to be connected to the outdoor.The chamber body has sound absorption,and the dust removal and noise reduction and grinding indoor working environment conform to the labor hygiene standard,which can effectively protect the occupational health and health of operators.
Two.Characteristics of equipment
1.,it can effectively reduce the grinding noise,eliminate dust and air and explosion-proof functions,and fully meet the requirements of the national workshop noise levels and air quality standards.
2.the grinding room can be used to connect the grinding operation to the production line without having to be set up separately.So that the grinding process can be integrated into the whole production process chain,and the local grinding is realized,which eliminates a lot of complicated transportation work.
3.layout makes the process continuous and smooth,and operates smoothly and conveniently,saving a lot of resources and improving production efficiency.
4.the air in the grinding room is cleaned by the sedimentation method and the cartridge type dust collector.The purified air is directly discharged into the workshop to avoid a large amount of air supply in the workshop.
5.,a muffler plate has been developed to achieve muffler effect,which effectively reduces noise.
6.pay attention to humanized design,safety first,prevention first,dust explosion design to ensure production safety.
7.maintaining the occupational health and safety of the operators,making the noise and air quality of the production workshop up to the state standard,in line with the"Three Simultaneity"requirements,and improving the production environment.
