一． 酒厂污水特点

1、 Characteristics of brewery wastewater

污水比较复杂、主要为乙醇、戊醇、丙醇、丁醇、脂肪酸、氨基酸、酯、醛；

The wastewater is complex, mainly including ethanol, pentanol, propanol, butanol, fatty acids, amino acids, esters and aldehydes;

污水浓度高、酿酒在固态发酵、蒸馏过程中会产生不同浓度的污水，水质浓度高、色度高；污水污染严重、污水可生化性好；污水混排、吨酒产污量大、污染严重的特点。

In the process of solid-state fermentation and distillation, different concentrations of wastewater will be produced, and the water quality has high concentration and high chroma; The pollution of sewage is serious and the biodegradability of sewage is good; It has the characteristics of mixed wastewater discharge, large amount of pollution per ton of liquor and serious pollution.

二． 酒厂污水处理方式

2、 Wastewater treatment methods of distillery

好氧处理法：

Aerobic treatment:

用好氧微生物降解物实现废水处理，不产生带臭味的物质，处理时间短，适应范围广，处理效率高；

Using aerobic microbial degradation products to realize wastewater treatment, there is no odor material, the treatment time is short, the application range is wide, and the treatment efficiency is high;

物理处理法：

Physical treatment method:

不投加药剂，限度地减少污泥产生量，工艺简单；

Without adding chemicals, the sludge production can be reduced to a certain extent, and the process is simple;

生化处理法：

Biochemical treatment method:

不该工艺，直接投加化学药剂，操作简单，并采取必要措施从而避免了产生二次污染，同时也实现达标排放处理。

It is easy to operate and take necessary measures to avoid the secondary pollution and achieve the standard discharge treatment.

酒厂废水降低cod的方法:

The methods of reducing COD in distillery wastewater are as follows

1、在沉淀池前投加希洁COD降解剂；

1. Add Xijie COD degradation agent in front of sedimentation tank;

2、把药剂溶解成10%的溶液；

2. Dissolve the reagent into 10% solution;

3、用提升泵，注入曝气池中，根据自动检测出来的出水数据而调节提升泵的频率，既不会影响现场的工艺，又能更加活动性地控制COD总出水浓度，有效地将COD控制在80ppm以下。

3. The frequency of the lift pump can be adjusted according to the automatically detected effluent data, which will not affect the on-site process, and can control the total effluent concentration of COD more actively, and effectively control the COD below 80ppm.

白酒废水除磷方法:

Phosphorus removal from Baijiu wastewater:

我国白酒生产大多数以高梁、小麦、玉米等作为原辅料，经过四道基本工序酿制而成，即原料的预处理、糖化发酵、蒸馏出酒、装瓶。这过程中会产生高浓度的含磷废水，白酒废水除磷方法一般分为生物法和化学法：

Most of the Baijiu production in China is made of sorghum, wheat and corn as raw materials, and is brewed by four basic processes, namely, raw materials pretreatment, saccharification and fermentation, distilling and bottling. In this process, high concentration phosphorus wastewater will be produced. The phosphorus removal methods of Baijiu liquor can be divided into biological and chemical methods.

(1)生物法：

(1) Biological method:

生物法除磷是指好氧型在一定条件下会对磷或者偏磷进行硝化分解，一部分磷会被微生物吸收，从而变为微生物污泥；另外一部分磷会被分解转化为为正磷小分子，在后续处理中，还要继续通过化学法将正磷小分子沉淀。从除磷效率来说，生物除磷法并不能把磷处理到低浓度，是因为微生物分解磷的能力有限，是磷残余在微生物的体内会因为新陈代谢而把磷排出。

Biological phosphorus removal means that under certain conditions, the aerobic type will decompose phosphorus or partial phosphorus by nitrification, and a part of phosphorus will be absorbed by microorganisms, thus becoming microbial sludge; Another part of phosphorus will be decomposed into small positive phosphorus molecules. In the subsequent treatment, small positive phosphorus molecules will continue to be precipitated by chemical method. From the perspective of phosphorus removal efficiency, biological phosphorus removal method can not treat phosphorus to low concentration, because the ability of microorganisms to decompose phosphorus is limited, and the phosphorus residue in the body of microorganisms will excrete phosphorus because of metabolism.

(2)化学沉淀法：

(2) Chemical precipitation method:

化学法除磷包括化学沉淀、离子交换、反渗透、电渗析等方法。以化学沉淀法应用广,后几种方法因处理费用太高而难以使用。

Chemical phosphorus removal includes chemical precipitation, ion exchange, reverse osmosis and electrodialysis. Chemical precipitation is widely used, but the latter methods are difficult to use because of the high cost.

一般来说，生物法能解决大部分的总磷，但不一定能完全降到排放标准以下且由于工艺老化、或者季节转变气温降低等原因会出现总磷浓度超标而工艺降不下来的时候。这时就需要生物法和化学沉淀法结合使用！

Generally speaking, the biological method can solve most of the total phosphorus, but it may not be able to completely reduce to below the emission standard, and because of the aging process, or the seasonal change of air temperature and other reasons, the total phosphorus concentration will exceed the standard and the process can not be reduced. At this time, we need the combination of biological method and chemical precipitation method!

化学沉淀法即投加除磷剂，这种方法的优势有：

Chemical precipitation method is to add dephosphorization agent

1、无需增加高额工艺设备

1. No need to add high cost process equipment

2、无需停产改造

2. No need to stop production

3、投加具有强烈的灵活性，可以根据实际情况调整投加量，成本可控

3. It has strong flexibility to adjust the dosage according to the actual situation, and the cost is controllable
