Under rainwash, the rural area on periphery is flowed to, serious pollution is formd, destroys ecology, the life of peasant is have impact on
Production and life.
Therefore, substantial amounts of cassava sludge is disposed, substantial amounts of fund is wasted every year, great economy is brought to production unit
Burden.
According to incompletely statistics, company has to waste every year more than 1,000 ten thousand yuan in the processing of cassava sludge, these funds
Input had a strong impact on business income and the economic growth of production unit, influence the survival and development of company.
The content of the invention
It is an object of the invention to provide a kind of innoxious, recycling technology, main path can be carried out to cassava sludge
It is exactly that first cassava sludge is pre-processed and fermented, is then used as the bait of earthworm, in order to realize this purpose, this hair
It is bright to adopt the following technical scheme that：
First, technical characteristics of the invention
1st, technical characteristic one：
New raw material.Have no the report for using the cassava sludge after pretreatment and fermentation as angleworm bait；Cassava sludge
The content of organic matter is very high, and about 40% or so.Also contain substantial amounts of methagen corpse in cassava sludge, protein content is high, because
This can as earthworm food.But because cassava sludge acidity is overweight, viscosity is too big, it is impossible to directly feed earthworm, otherwise
Earthworm can escape or dead.Therefore, pretreatment must be first passed through as the bait of earthworm and fermented.
2nd, technical characteristic two：
The pretreatment of cassava sludge.Have to be pre-processed before fermentation, pretreatment is just able to allow microorganism to exist
Growth and breeding in the cassava sludge of stack retting, the adjustment of physico-chemical property is carried out to cassava sludge, treatment technology will be according to each batch
After secondary cassava sludge is detected, pre-processed further according to testing result.Such as, acidity is adjusted into limewash
Property；Plus leavening agent is into cassava sludge and mixes, change ventilative situation.Directly fed as without adjusting acid-base value to neutral left and right
Earthworm can make earthworm escape, body swelling or toxic reaction.
3rd, technical characteristic three：
Fermentation.Pile fermentation is carried out after pretreatment, the auxiliary material and strain added during pile fermentation is innovation.Auxiliary material is according to this
Ground principle uses the Pleurotus eryngii waste chaff of batch production, for reducing the viscosity of sludge, has been conducive to the breeding of bacteria；Strain is
The fermenting organism bacterium independently screened.After by fermentation, raw material becomes loose, soft, tender, thin, and acidity, moisture, smell are suitable for earthworm
Afterwards, can as earthworm base-material or bait.
4th, technical characteristic four：
Breeding way.Using composting breeding earthworm, sufficient bait is disposably put, enough growth cycles, usually 1-2 months,
Until harvest time.This mode is breeding way in situ, high-density breeding, it is not necessary to covered, but is needed in fermentation heap surrounding
Gutter is dug.Without adding virgin material, without removing wormcast, only note keeping the skin wet.
5th, technical characteristic five：
Harvesting approach.Generally, commodity earthworm is in harvest, manually separately earthworm and wormcast, but this work is very
Time-consuming work consuming, cost hardly possible reduction.Therefore, one of content of this patent is exactly to develop suitable product, such as biological feedstuff, changes tradition
Clastotype, not separated earthworm and wormcast, direct dries pulverizing makees the base-material of biological feedstuff after removal of impurities.
6th, technical characteristic six：
Make new biological feedstuff.Single product earthworm or wormcast are all that protein content is very high, especially earthworm,
All it is especially suitable for doing in aquatic feeds, therefore this patent, earthworm is not required to be separated with wormcast.When the growth cycle of earthworm is completed
Afterwards, the earthworm of whole batch is used as the raw material of biological feedstuff with wormcast, and first removal of impurities, reheating air drying is finally crushed, mixed
With the auxiliary materials such as wheat bran, packed products, storage is preserved.
2nd, main production flow of the invention
The main production flow of the present invention（That is implementation steps）It is as follows：
1st, step one：
Detect the physico-chemical property of each batch cassava sludge, including pH value, moisture content, viscosity, the content of organic matter, the residual content of agriculture,
