There Are Still Many Debates On The Technology Of Printing And Dyeing Sludge Treatment And Disposal.

< p > reduction is a common way to deal with pollutants. < a href= "//www.sjfzxm.com/news/index_c.asp" > dyeing sludge < /a > treatment is no exception.

The disposal and disposal of sludge need several steps, such as separation, stabilization, digestion, dehydration and disposal, which require a lot of capital investment and high operation cost. Finally, the sludge needs to be disposed of by means of landfill and incineration. With the reduction of available land resources and the occurrence of the two pollution problem, people have focused their attention on the biological treatment process that can reduce sludge production.

The sludge is pretreated by P. The aim of reducing the load of sludge treatment and disposal can be achieved by reducing the source of the sludge.

At present, the research on sludge reduction technology at home and abroad mainly focuses on several aspects, such as promoting sludge cell lysis, uncoupling technology and the predation of microanimals in food chain.

< /p >

< p > although the source reduction of sludge is a new idea of < a href= "//www.sjfzxm.com/news/" > sludge treatment > /a > disposal technology, sludge is the key to sewage treatment, and the reduction of sludge source will inevitably affect the water quality.

Industry experts also have doubts about this technology.

Sludge reduction technology should reduce sludge production without affecting the efficiency or efficiency of sewage treatment process. Experts believe that economic feasibility, ease of operation and management and long-term benefits will be the research target of sludge source reduction technology.

< p > < strong > disposal is a necessary condition for resource utilization < /strong > /p >

< p > > a href= "//www.sjfzxm.com" > resource < /a > has always been regarded as the ultimate goal of waste disposal, and the sludge disposal and disposal industry also has the idea of "resourceful".

Sludge recycling technology can not only effectively dispose of sludge, but also achieve the purpose of recycling economy.

The existing technologies for sludge utilization include compost technology, biogas production technology, fuel technology and building materials utilization.

< /p >

< p > however, the utilization of sludge resources is conditional.

Sludge can be regarded as a resource, which does not mean that sludge is a commodity with paction value. Only after disposing and disposing of sludge, can the water content and stability reach a certain degree before it can be converted into heat or building materials.

Without processing and disposal, sludge recycling characteristics can not be seen.

Experts suggest that while promoting sludge recycling, relevant departments should recognize the relationship between sludge disposal and understand that sludge recycling needs to be excavated and invested. We should not blindly promote the problem of idle capacity and low cost performance.

Only by clearing the dialectical relationship can we achieve safe disposal and rational utilization of sludge.

< p > < strong > high cost and two pollution burn is hidden danger < /strong > < /p >

< p > a href= "//www.sjfzxm.com/news/" > sludge incineration technology < /a > can completely remove the water and organic matter in the sludge, and kill pathogens, only get a small amount of sludge ashes, and can generate electricity by thermal energy. It is considered the most potential sludge disposal technology.

Sludge incineration power generation is harmless and resource oriented. In recent years, it has been sought after by people in the industry.

< /p >

< p > however, with the two pollution problems of sludge incineration process, the most common headache is dioxin.

During the incineration process, the toxic organic compounds contained in the sludge form dioxins under the catalysis of metal oxides.

Incineration also brings dust and heavy metal pollution, as well as odors. These problems must be considered.

Sludge incineration power generation should not only consider the influence of corrosion generated by incineration on power station equipment, but also try to improve the energy utilization rate of incineration sludge.

< /p >

At present, China has followed the principle of "reduction, stabilization and innocuity" in the selection of sludge treatment processes, followed by source reduction and whole process control, and strengthened the source control of toxic and hazardous substances. P

According to the final safe disposal requirements of sludge and sludge characteristics, appropriate sewage and sludge treatment processes are selected to achieve proper disposal of sludge under the premise of safety and environmental protection.

At the same time, the State encourages the recovery and utilization of energy and resources in the sludge to achieve the purpose of energy saving and emission reduction and < a href= "//www.sjfzxm.com" > circular economy < /a >.

China's sludge treatment and disposal business is still in a state of "contention of a hundred schools of thought". After the market's "ebb tide", the technology of stability, economy and good energy saving and emission reduction will come to the fore.
