Description
Technical field
The present invention relates to filth disposal technical field, organic fertilizer and its system are processed in particular to a kind of domestic sewerage
Preparation Method.
Background technology
For environmental protection, sewage treatment plants are designed with present city.The sanitary sewage of city dweller is by pipe
Road enters sewage treatment plants, by processes such as oxygenation, stirring, fermentation, precipitations, sewage is become into clean, free of contamination water,
River course and urban water resource are protected, environment is protected.But at this simultaneously, can be produced during treatment city domestic sewage big
The sludge of amount.The organic substance contained in sanitary sewage becomes sludge settling after treatment and gets off, and big and small daily is various
Sewage treatment plants can all produce substantial amounts of sludge.Here it is sanitary sewage disposal sludge, also known as biological sludge.Sanitary sewage
In treatment sludge, the moisture content containing 70-80% contains organic matter and n-p-k element.City domestic sewage treatment plant set up with
Come, people are making great efforts how research utilizes sanitary sewage disposal sludge always, particularly it is intended that using sanitary sewage disposal
The fertilizer that sludge manufacture agricultural production is used, but produce little effect.Environmental administration, agricultural sector put into substantial amounts of funds for a long time
And manpower, cannot all solve this problem.Its basic reason is：Moisture in sanitary sewage disposal sludge is colloid water, no
It is free state water.The method of the treatment free state water such as moisture in traditional object is with extracting, press dry, dry, dry, wind is dry
To process the colloid water in sludge all without effect.The method that such as domestic unit having high temperature is dried processes sludge, as a result
Moisture is oven-dried, and the organic matter in sludge becomes simple substance carbon by high-temp combustion, and inorganic states are changed into from organic, loses and does
It is the function of fertilizer.Because prior art cannot utilize sanitary sewage disposal sludge, sludge to be stacked on sewage treatment plant for a long time
In, form secondary pollution.This problem long-term existence, it is impossible to solve, sludge piles up more and more, as one in the urgent need to solution
Big problem certainly.It is good agricultural production fertilizer due to containing organic matter and n-p-k element in sanitary sewage disposal sludge.
Therefore the preparation method that the sludge remained after a kind for the treatment of with city domestic sewage manufactures organic fertilizer and the organic fertilizer is invented
It is very necessary.
