Food processing wastewater treatment process design and equipment Projects Author: industry production and people's life are inseparable from the water, but for various reasons that make people's water consumption continues to increase, especially in a large number of food processing wastewater, food processing wastewater treatment The use of equipment brings the greatest benefits to the survival and development of human society, and at the same time has become an indispensable part of society. Environmental protection has many years of water treatment experience in food processing wastewater treatment equipment. Next, environmental protection will introduce you to the project characteristics of food processing wastewater treatment equipment. Due to the wide variety of foods and wide sources of raw materials, wastewater from the food industry has suspended solids, high oil content, heavy metal ions, large COD and BOD values, who knows that the amount of water varies greatly, and the content of nitrogen and phosphorus compounds is high. In some cases, the water temperature Also higher features.  Sewage treatment process is divided into primary treatment, secondary treatment and tertiary treatment. For food industry wastewater, the primary treatment generally uses solid-liquid separation technology to remove suspended solids and floating substances in the wastewater. Secondary treatment is the main treatment process. Biological treatment technology is generally used to remove toxic substances such as organics in water, and membrane treatment and strong oxidants are generally used to further evolve wastewater.  Features of food processing wastewater treatment  Food wastewater will produce sludge, waste oil, waste acid, waste alkali during the treatment process, and the animal and plant waste generated during the processing should also be treated in a harmless manner.   Food processing wastewater mainly comes from three production sections.   (1) Raw material cleaning section. A large amount of sandy soil debris, leaves, skins, scales, flesh, feathers, hairs, etc. enter the wastewater, causing the wastewater to contain a large amount of suspended solids.  (2) Production section. Many ingredients in the raw materials cannot be fully utilized in the processing process, and the unused part enters the wastewater, making the wastewater contain a large amount of organic matter.  (3) Forming section. In order to increase the color, aroma, and taste of food, and extend the storage period, various food additives are used, and some of them are lost into the wastewater, making the chemical composition of the wastewater complicated.   The water quantity and quality characteristics of food processing wastewater are mainly reflected in six aspects:    (1) Production changes with seasons, and wastewater quality and quantity also change with seasons. (2) The amount of wastewater varies. The food industry has a wide range of products from small-scale household industries to various large-scale factories. The raw materials, processes, and scales vary greatly. The amount of wastewater varies from several m3/d to thousands of m3/d. d varies. (3) There are many degradable components in food industry wastewater. For the general food industry, since the raw materials are derived from natural organic substances, the components in the wastewater are mainly natural organic substances and do not contain toxic substances, so it is biodegradable. Its BOD5/COD is as high as 0.84.  (4) There are many high-concentration wastewater.  (5) Wastewater contains various microorganisms, including pathogenic microorganisms, and the wastewater is prone to decay and smell.  (6) The wastewater contains high nitrogen and phosphorus content. Introduction to Food Processing Wastewater Treatment Process When choosing a food discharge sewage treatment process, you must not only consider the composition of harmful substances in the sewage, but also understand the instantaneous changes in the quality and volume of the discharged sewage. These are very important for the selection of sewage treatment processes, equipment, and future operation and management. important. Larger suspended solids and grease in food processing wastewater can be removed by suspension separation technology, suspended solids in water (including colloids) represented by SS value can be removed by solid-liquid separation technology; harmful substances represented by COD, BOD, etc. in sewage can be used Removal by biological treatment technology; the treated water must be disinfected before being discharged, and the sludge produced in the biological treatment process must be dehydrated and discharged.
