Abstract
A kind of method of the processing of sewage when slaughtering young sheep, is related to killing fowl technical field, it is characterised in that：Including following operating procedure, processing pond is established, processing pond is divided, handled.The method of the present invention is reasonable, easy to operate, processing is convenient.
Description
Technical field
The present invention relates to killing fowl technical fields, and in particular to a kind of method of the processing of sewage when slaughtering young sheep.
Background technology
Goat (scientific name:Capra aegagrus hircus) summer sheep, black Yang Huo Black-ewe sheep are also known as sheep, it is earliest
One of domestic animal by mankind's domestication.
Chinese Goat raising is with a long history, just has sheep raising literature record early in quotient's epoch summer.Goat Raising has breeding potential
The features such as high, adaptable, manageability, raises extensively in the vast farming and pastoral area of China so far.Since reform and opening-up, Chinese Goat industry
It quickly grows, outstanding achievement.The area of Chinese Goat distribution is wide, and throughout the whole nation, there is province (area) the goat head of more than half in the whole nation
Number is more than sheep.The place that some provinces (area) of south cannot support sheep can but support goat.
Goat can change plant community and forest structure, and disease can be transmitted to primary animal, international conservation of nature
The invasive species panel of expert (ISSG) of the species survival committee of alliance is classified as hundred big Alien invasive species of the world.
Young sheep is also known as lamb, is the general designation of the cub of sheep.
And it is present particularly high for the environmental requirement in slaughterhouse when production and processing, and when sheep is slaughtered
The underproof discharge of impurity, waste water, the waste liquid of time etc. can all bring pollution and harm for environment, soil.
Invention content
The technical problems to be solved by the invention be to overcome existing technological deficiency provide a kind of method rationally, operation side
Just a kind of, method of the processing easily processing of sewage when slaughtering young sheep.
The technical problems to be solved by the invention are realized using following technical solution：
A kind of method of the processing of sewage when slaughtering young sheep, it is characterised in that：Including following operating procedure,
Step 1: establish processing pond：Establish a big rectangular or rectangular processing pond, being divided into four pieces can connect
Small processing pond；
Step 2: processing pond divides：Four pieces small processing pond carries out different filtration treatments, from side toward the first of opposite side
Block is first processing, three times after-treatment, processing, four processing；
Step 3: it is handled：
I is passed through sewage in the pond just handled, is naturally settled, and after-treatment is passed through after 2-4 hour；
II is put into adsorbent in the pond of after-treatment, is adsorbed by adsorbent, is then passed through three times after 2-4 hour
Processing；
III is put into absorbent in the pond handled three times, is absorbed by absorbent, is then passed through four times after 2-4 hour
Processing；
IV carries out natural subsidence in the pond of four processing, and is put into the grid that 50-60 mesh sieves in pond and is filtered, 5-
It is discharged after 6 hours；
1 part of 10 parts of material molysite, the starch that the adsorbent includes parts by weight is made；
Its preparation method is：
Starch is added clear water and then adds sodium hydroxide by I, is stirred at 50-60 DEG C 30-40 minutes, it is molten that starch is made
Liquid；
II uses soluble ferric iron salt, and molysite is adjusted acid-base value to pH0.1-4.0, starch solution is then added in, finely tunes pH
Recombination reaction is carried out for 0.5-4.5；
The starch：Clear water：The mass ratio of sodium hydroxide is 1：50：10；
The material that the absorbent includes following parts by weight is made,
20-30 parts of attapulgite, 5-9 parts of mica powder, 4-10 parts of sodium carbonate, 5-11 parts of alkanolamide, 2-6 parts of coal tar,
4-12 parts of silane resin acceptor kh-550,5-7 parts of polytetrafluorethylepowder powder, 4-9 parts of butyl methacrylate；
Preparation method is：
Attapulgite, mica powder are sent into calcining furnace by I, are calcined 3-4 hours at 300-400 DEG C, are taken out and crush, cross 20 mesh
Sieve adds in the water of 70 parts by weight, is stirred 10-12 hours under 100-200 revs/min, obtain attapulgite suspension；
II adds in other residual components in 35 parts by weight water, stirs, obtains slurry；
III hot-air that 50-60 DEG C is blown to attapulgite powder seethes it, then mist is sprayed into the powder seethed
The slurry that IIIth step obtains, after being sufficiently mixed the two, it is 50-60 DEG C to keep temperature, continues to seethe 30-40 minutes；
IV dries the mixed material in III, is then ground to particle and crosses 500-600 mesh sieve.
Beneficial effects of the present invention are：The separation that bulky grain and water can be autonomous is enabled to, then lead to by natural subsidence
Impurity, dust, molecule in water can be adsorbed by crossing adsorbent, can further be cleaned in this way, and be passed through suction again
Blood, bacterium, microorganism etc. can be adsorbed by receiving agent, can more thoroughly carry out absorption and sorption, further dedusting, removal of impurities
And purification, last sedimentation and filtering can remove the substance being filtered of former steps, thus it is clean very thoroughly,
And no pollution is also nontoxic.
