Description
Technical field
It is mixed the utility model is related to sludge and burns feeding technology field, and in particular to burning feeding system is mixed in a kind of sludge mixing.
Background technology
Municipal sludge is both pollutant and a kind of resource.Sludge is considered as a kind of resource to be efficiently used, is being administered
Turn waste into wealth while pollution, realize the recycling of sludge, there is significant environment and economic benefit.By former coal-fired small thermal motor
Group is changed to the comprehensive utilization of resources unit of burning mixed mud, on the one hand can alleviate the problem of a large amount of Treatment of Sludge hardly possiblies at present, avoid filling out
Environmental pollution caused by burying etc., while reducing the construction cost and sludge transportation cost for creating sludge treatment plant；It on the other hand can
The calorific value of sludge is made full use of to carry out power generation and heat supply.
If sludge is dealt with improperly, can cause environmental pollution：
1, sludge salt content is higher, can significantly improve soil conductivity, destroy soil nutrient balance, inhibits plant to nutrient
Absorption.Even root system of plant is caused directly to injure, and interionic antagonism can accelerate the leaching loss of available nutrient.
2, the pathogen in sewage (pathogenic microorganism and parasite) can also enter sludge by processing.It is examined in fresh sludge
Up to thousand kinds of the pathogen measured, wherein it is parasite to endanger larger.Pathogen is big to the pollution channel of mankind or animal
Cause has 4：(a) it is directly contacted with sludge；(b) it is in direct contact and infected with sludge by food chain；(c) water source is by pathogen dirt
Dye；(d) pathogen polluted soil first, then polluted-water.
3, after largely using the sludge containing N, P etc. on the soil of rainfall larger area, when organic matter decomposition rate
When more than plant to the infiltration rate of N, P, the nutrients such as N, P are possible to outflow with water and cause water body rich into surface water body
Nutrient laden causes underground water pollution into underground water.
4, organic matter high polymer pollutes.Mainly there are benzene, chlorophenol etc. in municipal sludge.Although at present both at home and abroad to municipal sludge
The research of middle organic pollution is simultaneously few, but some countries are to the feature of organic pollution in agricultural sludge and its in agriculture ring
Behavior, ecological effect and regulation measure in border etc. have carried out certain research.Western developed country is to organic in sludge
The concentration of pollutant has carried out certain limitation.
5, heavy metal pollution.In sewage disposal process, 70%~90% heavy metal element is by absorbing or precipitating
It is transferred in sludge.Some heavy metal elements are mainly derived from the waste water of industrial discharge, such as some sources of heavy metal of cadmium, chromium in
The pipe-line system of family life.An important factor for heavy metal is limitation sludge extensive land use, because sludge is applied to soil
After earth, heavy metal will build up in surface layer.In addition, the general solubility of heavy metal is small, property is relatively stablized, hardly possible removes, so it is latent
It is easy to accumulate in crop and animal and the mankind in toxicity.
Sludge is used, is turned waste into wealth, needs to be handled by reasonable manner thus, a kind of system is needed
It carries out the processing of sludge and then burns.
