Description

A kind of natural component sewage of farm flocculant

Technical field

The invention belongs to sewage treatment area, particularly to a kind of natural component sewage of farm flocculant。

Background technology

Livestock breed aquatics field sewage is that surrounding enviroment are polluted topmost source by livestock-raising field, and big plant pollutes very serious, and the even individual raiser of little plant, the sewage of its outflow is also the principal element causing ambient contamination。Animal husbandry sewage mainly includes cattle waste, colony house wash water, pipe flushing water, discarded drinking water etc., wherein cattle waste is main polluter, process around cattle waste, there are big quantity research and Related product and complete set of equipments, but the sewage that animal husbandry produces also includes colony house wash water, wherein contains substantial amounts of disinfectant agrochemical；Also include pipe flushing water, wherein contain substantial amounts of soda acid liquid；Also include discarded drinking water, wherein contain ingredient etc.。Simple use compost or solid-liquid separating equipment, can only separate cattle waste solid and liquid, and solid is made into fertilizer after treatment, but liquid component is complicated, and permeability is strong, and direct discharge can cause bigger pollution。Although may be used for producing biogas, but the construction of methane-generating pit and maintenance cost are all higher, therefore in practice or with after carrying out solid-liquid separation, liquid enters Bilge or cesspool, after natural sedimentation, standing processes or enters after Air Exposure breed fish sugar or artificial swamp or just directly discharge。

Now there are some researches show; to animal husbandry sewage; if water pollutant can be allowed to precipitate; can will significantly alleviate the pressure of sewage subsequent treatment; therefore the livestock-raising field of scale all adopts and first precipitates the mode discharged afterwards and process sewage, the sewage after precipitation process, it is possible to carry out a biological disposal upon mode for fish pond, artificial swamp etc.; sewage disposal is fallen the most at last, and therefore precipitation link is extremely important。Generally having natural sedimentation, inorganic flocculating agent precipitation, microorganism precipitation, organic flocculant precipitation several ways at present, and natural sedimentation method efficiency is low, the dirty water pollutant index of discharge is high, and subsequent treatment causes bigger pressure；Inorganic flocculating agent adopts chemical products, the secondary pollution more serious to easily causing harm in the mud precipitated and upper strata water body；Microbial flocculant is relatively big by using environmental effect, and effect is unstable；Organic flocculant is reasonable precipitation process mode, but adopts organic flocculant to need treatment in accordance with local conditions, if adopting the organic matter of synthetic, adds in the sewage of complicated component, it is possible to cause secondary pollution, it is therefore desirable to adopt the organic substance of natural component。Chinese patent 201310481165.0 discloses a kind of livestock-raising field sewage treatment flocculating agent, adopt leaf of Herba Apii graveolentis powder and Herba Dendrobii leaf powder that the sewage of livestock-raising field is carried out flocculation sediment, achieve comparatively ideal effect, but Herba Dendrobii is a kind of rare Chinese medicine originating in China, this type of plant is with stem for medicine, and original blade is just fewer, in business breeding, lay particular emphasis on long shoot especially, blade is wanted little and is lacked, and therefore Herba Dendrobii leaf powder is not readily available；And leaf of Herba Apii graveolentis powder also compares difficult acquisition, because Herba Apii graveolentis is all that even blade is sold, business-like leaf of Herba Apii graveolentis or leaf of Herba Apii graveolentis powder are not sold, and the production of this type of natural organic flocculant is promoted and is restricted。

Summary of the invention

It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the sewage of farm flocculant of a kind of complete pure natural components。

Technical scheme is as follows:

A kind of natural component animal husbandry sewage flocculant, its component and weight content are as follows:

Preferably, wherein said chitosan molecule amount is 10-30 ten thousand。

Preferably, wherein said eucalyptus leaves powder is that the eucalyptus leaves dried is crushed to 30-80 order。

Preferably, wherein said Eucalyptus fruit powder is that the Eucalyptus fruit dried is crushed to 30-80 order。

Preferably, wherein said Rhizoma Solani tuber osi corium farinosum is that the potato peel dried is crushed to 30-80 order。

Preferably, wherein said zeolite powder is 10-30 order。

Chitosan is the natural polymer obtained from shrimp Eriocheir sinensis shell, now there are some researches show, with chitosan, sewage is processed, the content of the turbidity of sewage, COD, organic substance, heavy metal ion and float can be effectively reduced, its effect is better than activated carbon, and use that chitosan and zeolite and activated carbon are proportioned, its treatment effect is better than and uses merely chitosan。

Eucalyptus is a kind of commodity trees extensively planted at south China, has the quick feature of growth。Eucalyptus processing factory generally only selects Eucalyptus branch, and substantial amounts of eucalyptus leaves and Eucalyptus fruit are only used as leftover bits and pieces and sell, less expensive, is generally used for extracting Eucalyptus oil。The useful eucalyptus leaves of locals is to boil water to wash one's face, it is possible to have sterilizing skin Caring except effect of pox print, and additionally Japan's current research shows, Eucalyptus oil has effect of degraded bisphenol-A。

Rhizoma Solani tuber osi has a large amount of plantation throughout the country, and Related product producer is more, has substantial amounts of potato peel leftover bits and pieces, generally inexpensively can sell to livestock-raising field as feedstuff。Containing compositions such as substantial amounts of Plant fiber, pectin, starch in potato peel, possibly together with micro constitutents such as vitamin, phenols, aldehydes, ketones, the present inventor first by potato peel and eucalyptus leaves powder, Eucalyptus fruit powder, chitosan and zeolite powder in combination as sewage treatment flocculating agent, achieve desirable effect, but Rhizoma Solani tuber osi corium farinosum addition is no more than 30%, excessive Rhizoma Solani tuber osi corium farinosum can cause that water body produces stench on the contrary。

Beneficial effects of the present invention is as follows:

1. flocculation sediment effect is notable: the present invention first by chitosan, eucalyptus leaves powder, Eucalyptus fruit powder, Rhizoma Solani tuber osi corium farinosum and zeolite powder in combination as sewage flocculant, in actual experiment, the amount that liquid after the solid-liquid separation of livestock-raising field is pressed 1kg/ side puts into, standing 16-24 hour after stirring, flocculating effect is notable。Animal husbandry sewage complicated component, potato peel, eucalyptus leaves powder and Eucalyptus fruit powder are applied in flocculant by the present invention first, with other, there is the composition combined effect of water purification effect, utilize in these plants the micro constitutents such as composition and vitamin, phenols, aldehydes, ketone such as abundant Plant fiber, pectin, starch, add the organic component classification of flocculation system, be conducive to the animal husbandry sewage generation chemical action with complicated component, generate oarse-grained flocculent deposit。

2. purifying water effect is notable: use the flocculant of the present invention, upper strata water body after staticly settling is limpider, smell and do not have abnormal flavour, and owing to the Eucalyptus oil content in eucalyptus leaves and Eucalyptus fruit is higher, there is sterilizing effect, water body subsequent treatment pressure after flocculation treatment is little, enters the water of fishpond or artificial swamp all without the death causing fish or plant after Air Exposure, illustrates that flocculant is by major part pollutant flocculation sediment out。

3. flocculation sediment Biodegradable: the flocculant composition of the present invention is all natural materials, after reacting with animal husbandry sewage, chelate or complex is formed with pollution element therein, it is precipitated out formation mud, these mud contain substantial amounts of organic matter, belong to degradable humus sludge, and only need to carry out simple compost treatment can form fertilizer, or after harmless treatment, directly imbed underground, will not to environment。

4. with low cost, non-secondary pollution: preparation method of the present invention is simple, various composition Dou You factory can inexpensively buy in a large number, only need to dry and be crushed to suitable fineness, mix in proportion。Eucalyptus leaves, Eucalyptus fruit, potato peel are all plants, and in order to make plant cell greater area of with sewage to contact, powder must be more thin more good, but too carefully can increase again processing cost, finds 30-80 order best results through great many of experiments, and it is the most convenient to process。The more little purifying water effect of chitosan molecule amount is more good, but is cost consideration, selects 10-30 ten thousand molecular weight, price economy material benefit, and result of use is good。
