Abstract
The invention discloses a kind of many raw material alcohol waste water total nitrogen total phosphorus minimizing technologies.Method is in many raw material alcohol waste water and clear liquids, 5.5~6.5kg/t sewage polyaluminum sulfate iron adsorbent 50~60ppm polyacrylamide flocculants are put into successively, separation of solid and liquid is being carried out by tilted plate separator, solid goes to the dehydration of plate frame filter press, and waste liquid, which enters, enters alcohol waste water processing system after Clear liquid tank.Waste liquid nitrogen removal rate is 47.54%~52.84%, and total tp removal rate is 44.08%~58.02%.The present invention solves the qualified technical problem of waste liquid total nitrogen total phosphorus key index in fermentation alcohol industry.The processing method of the alcohol waste water to many raw materials is provided for a large amount of Alcohol Plants, this method investment is small, with good application prospect.
Description
Technical field
The invention belongs to the technical field of alcohol waste water processing, specifically a kind of many raw material alcohol waste water total nitrogen total phosphorus removal sides
Method.
Background technology
Alcohol industry is the important basic material industry of national economy, and alcohol is widely used in chemical industry, food industry, day
The fields such as change, medical and health.The raw material of current China Alcohol Production is mainly the starchy materials such as corn, potato class, paddy rice.Because
Maize raw material crude protein 8~10%, rice crude protein 7.7% or so, potato class is generally 3% or so, therefore corn alcohol waste water and big
Rice alcohol waste water total nitrogen total phosphorus content is more, it is common to use protein feed product is made in evaporation concentration device, produces low concentration and steams
Send out condensate wastewater；And the relatively low nutriment of waste liquid total nitrogen content of potato class is low, need directly to handle row up to standard by biochemical process
Put.
Current country GB 27631-2011<Fermentation alcohol and Liquor-making industry pollution discharge standard>Have to total nitrogen total phosphorus
Limitation requires that wherein total nitrogen discharges total nitrogen≤50mg/l, total phosphorus≤3mg/l indirectly.If realizing cassava, jade on same production line
Many raw material alcohol wastewater treatments such as rice, paddy rice, it is necessary to effective pre-treatment is carried out to the total nitrogen total phosphorus in corn and rice waste water,
Otherwise original follow-up water treatment efficiency can be influenceed, it is impossible to qualified discharge.
The content of the invention
The present invention is to carry out pre-treatment to alcohol clear liquid using bodied ferric sulfate and polyacrylamide, and waste water is greatly lowered
In total nitrogen total phosphorus refer to calibration method.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of many raw material alcohol waste water total nitrogen total phosphorus minimizing technologies, in many raw material alcohol waste water and clear liquids, put into 5.5 successively
~6.5kg/t sewage polyaluminum sulfate iron adsorbent 50~60ppm polyacrylamide flocculants, are consolidated by tilted plate separator
Liquid is separated, and solid goes to the dehydration of plate frame filter press, and waste liquid, which enters, enters alcohol waste water processing system, waste liquid total nitrogen after Clear liquid tank
Clearance is 47.54%~52.84%, and total tp removal rate is 44.08%~58.02%；Many raw material alcohol waste water and clear liquids
It is that, with corn, potato class, paddy rice is the waste water that raw material produces alcohol.
Advantages of the present invention is as follows：
(1) most total nitrogen total phosphorus is anticipated to clear liquid by the inventive method, the processing for reducing subsequent handling is difficult
Degree.
(2) inventive method saves the medicament usage amount of subsequent handling.
(3) inventive method, by the procedure, nitrogen removal rate 47.54%-52.84%, total tp removal rate 44.08%-
More than 58.02%.
Embodiment
With reference to embodiment, the invention will be further described.

A kind of many raw material alcohol waste water total nitrogen total phosphorus minimizing technologies, in many raw material alcohol waste water and clear liquids, put into successively
5.5kg/t sewage polyaluminum sulfate iron adsorbent 50ppm polyacrylamide flocculants, after sloping plate deposition solid-liquid separation, give up
Liquid nitrogen removal rate is 47.54%, and total tp removal rate is 44.08%.
Embodiment 2
A kind of many raw material alcohol waste water total nitrogen total phosphorus minimizing technologies, in many raw material alcohol waste water and clear liquids, put into successively
6kg/t sewage polyaluminum sulfate iron adsorbent 55ppm polyacrylamide flocculants, after sloping plate deposition solid-liquid separation, waste liquid
Nitrogen removal rate is 50.46%, and total tp removal rate is 52.38%.
Embodiment 3
A kind of many raw material alcohol waste water total nitrogen total phosphorus minimizing technologies, in many raw material alcohol waste water and clear liquids, put into successively
6.5kg/t sewage polyaluminum sulfate iron adsorbent 60ppm polyacrylamide flocculants, after sloping plate deposition solid-liquid separation, give up
Liquid nitrogen removal rate is 52.84%, and total tp removal rate is 58.02%.
