Description

A kind of closed sludge drying fertilize preparation machine

Technical field

The utility model belongs to the environmental protection equipment field, is specifically related to quick mummification of a kind of closed mud and composting machinery.

Background technology

The target of country on the sludge treatment handling problems is to realize minimizing, the stabilization and innoxious of mud at present, and encourages to reclaim and utilize the energy and the resource in the mud; With the emphasis of sludge treatment disposal facility as the cities and towns infrastructure construction.

The mud that the municipal sewage plant produces in the process of disposing of sewage has the intensive stink, and contains parasitic ovum, pathogenic micro-organism and heavy metal because water cut is high, perishable, and as not dealing carefully with, discharging will cause secondary pollution arbitrarily.In sludge treatment, traditional sludge incineration, compost and landfill not only waste money, and the waste soil, and this just needs a kind of disposal technology of sludge treatment efficiently.Owing to also contain organic and abundant nitrogen, phosphorus, potassium and other trace element in the mud,, then help to solve the problem of a lot of sludge of sewage treatment plant treatment and disposal if it is processed fertilizer in a short period of time.

Reach the purpose of mud composting, at first will carry out sludge drying, promptly reduce the water ratio of mud; And then carry out compost.Mechanical dehydration is a kind of common sludge drying mode, but power consumption is big, and receives the influence of water technology in early stage, need carry out modified earlier.

Mix the purpose that also can reach sludge drying through mud and unclassified stores, but common mud fertilize preparation machine and sludge drying machine separate, not only increased floor space, also the more manpower of needs is operated.

The utility model content

There are deficiencies such as power consumption is big, floor space is big in order to overcome existing sludge drying and mud composting equipment; The purpose of the utility model is: a kind of closed sludge drying fertilize preparation machine is provided; This sludge drying fertilize preparation machine can disposable completion mud mummification and composting, need not carry out the modified of mud, take up an area of few; The mud composting time is short, improves composting efficient; And product is innoxious, the resource utilization degree high, can in the sludge fermentation process, suppress varied bacteria growing, prevent stink and objectionable impurities; The level of automation of total system is high, and closed equipment helps environmental protection and safety in production, cuts down the consumption of energy.

It is following that the utility model solves the technical scheme that its technical problem adopted:
