一、食品加工污水的特点
食品工业的内容极其复杂，包括制糖、酿造、肉类、乳品加工等生产过程，所排出的废水都含有机物，具有强的耗氧性，且有大量悬浮物随废水排出。动物性食品加工排出的废水中还含有动物排泄物、血液、皮毛、油脂等，并可能含有病菌，因此耗氧量很高，比植物性食品加工排放的废水的污染性高得多。
食品工业原料广泛，制品种类繁多，排出废水的水量、水质差异很大。但总体来说食品废水中主要污染物有：
（1）漂浮在废水中固体物质，如菜叶、果皮、碎肉、禽羽等；
（2）悬浮在废水中的物质有油脂、蛋白质、淀粉、胶体物质等；
（3）溶解在废水中的酸、碱、盐、糖类等；
（4）原料夹带的泥砂及其他有机物等；
（5）致命病菌等。
食品工业废水的普遍特点是有机物质和悬浮物含量较高，易腐败，一般无大的毒性。其危害主要是使水体富营养化，以致引起水生动物和鱼类的死亡，促使水底沉积的有机物产生臭味，恶化水质，污染环境。
食品污水处理设备特点食品废水在处理过程中会产生污泥、废油、废酸、废碱、加工过程中产生的动植物废弃物也应该进行无害化处理。食品加工废水主要来自三个生产工段。
（1）原料清洗工段。大量砂土杂物、叶、皮、鳞、肉、羽、毛等进入废水中，使废水中含大量悬浮物。
（2）生产工段。原料中很多成分在加工过程中不能全部利用，未利用部分进入废水，使废水含大量有机物。
（3）成形工段。为增加食品色、香、味，延长保存期，使用了各种食品添加剂，一部分流失进入废水，使废水化学成分复杂。
食品加工废水的水量水质特性主要体现在6个方面：
（1）生产随季节变化，废水水质水量也随季节变化。
（2）废水量大小不一，食品工业从家庭工业的小规模到各种大型工厂，产品品种繁多，其原料、工艺、规模等差别很大，废水量从数m3/d到数千m3/d不等。
（3）食品工业废水中可降解成分多，对于一般食品工业，由于原料来源于自然界有机物质，其废水中的成分也以自然有机物质为主，不含有毒物质，故可生物降解性好，其BOD5/COD高达0.84。
（4）高浓度废水多。
（5）废水中含各种微生物，包含致病微生物，废水易腐败发臭。
（6）废水中氮、磷含量高。

1. Characteristics of food processing sewage
The content of the food industry is extremely complex, including sugar production, brewing, meat, dairy processing and other production processes. The waste water discharged contains organic matter, has strong oxygen consumption, and a large number of suspended matter discharged with the waste water. The waste water discharged from animal food processing also contains animal excrement, blood, fur, oil, etc., and may contain bacteria, so the oxygen consumption is very high, which is much higher than that of the wastewater discharged from plant food processing.
The food industry has a wide range of raw materials, a wide variety of products, and the water quantity and water quality of the discharged wastewater vary greatly. But in general, the main pollutants in food wastewater are:
(1) Solid substances floating in the waste water, such as vegetable leaves, fruit peel, broken meat, poultry feathers, etc.;
(2) The substances suspended in the wastewater include oil, protein, starch, colloidal substances, etc.;
(3) Acid, alkali, salt, sugar, etc., dissolved in the wastewater;
(4) mud sand and other organic matter ained by raw materials;
(5) deadly bacteria, etc.
The general characteristics of food industry wastewater are the high content of organic substances and suspended matter, easy to corrupt, and generally no great toxicity. Its main harm is to make the water eutrophication, resulting in the death of aquatic animals and fish, promote the organic matter deposited in the bottom to produce odor, deteriorate the water quality, and pollute the environment.
Characteristics of food sewage treatment equipment Food wastewater in the process of treatment will produce sludge, waste oil, waste acid, waste alkali, processing process produced in the process of animal and plant waste should also be harmless treatment. Food processing wastewater mainly comes from the three production sections.
(1) Raw material cleaning section. A large number of sand and debris, leaves, skins, scales, meat, feathers and hairs into the waste water, so that the waste water contains a large amount of suspended matter.
(2) Production section. Many components in the raw material can not be fully used in the processing process, the unused part into the wastewater, so that the wastewater contains a large amount of organic matter.
(3) Forming section. In order to increase the food color, aroma and taste of the food and extend the storage period, various food additives are used, and part of the loss into the wastewater, making the chemical composition of the wastewater complex.
The water quality characteristics of food processing wastewater are mainly reflected in six aspects:
(1) Production changes with the season, and the water quality and quantity of wastewater also changes with the season.
(2) The amount of wastewater is different, the food industry from small-scale household industry to various large factories, a variety of products, its raw materials, technology and scale are very different, the amount of wastewater from m3 / d to thousands of m3 / d.
(3) There are many biodegradable components in the food industry wastewater. For the general food industry, because the raw materials come from natural organic substances, the components in the wastewater are also mainly natural organic substances, which do not contain toxic substances, so the biodegradability is good, and its BOD 5 / COD is as high as 0.84.
(4) High concentration of wastewater.
(5) The wastewater contains a variety of microorganisms, including pathogenic microorganisms, and the wastewater is easy to rot and stink.
(6) High content of nitrogen and phosphorus in the wastewater.
