Fruit and vegetable cleaning sewage treatment equipment analysis

First, the analysis of fruit and vegetable cleaning sewage treatment equipment

Fruit and vegetable processing sewage characteristics:

The food industry has a wide range of raw materials and a wide variety of products. The amount of water and water quality discharged from wastewater are very different. The main pollutants in the wastewater are: (1) solid substances floating in the wastewater, such as vegetable leaves, peels, minced meat, bird feathers, etc.; (2) substances suspended in the wastewater are oils, proteins, starches, colloids, etc.; 3) Acids, alkalis, salts, sugars, etc. dissolved in waste water: (4) muddy sand and other organic matter entrained in raw materials; (5) pathogenic bacteria and the like. The waste water of the food industry is characterized by high content of organic substances and suspended solids, easy to be spoiled, and generally no major toxicity. The hazard is mainly to make the water body eutrophication, causing the death of aquatic animals and fish, causing the organic matter deposited on the bottom to produce odor, deteriorating water quality and polluting the environment.

Fruit and vegetable cleaning sewage treatment equipment is a new type of sewage treatment equipment that combines years of experience and research. It has stable water supply, convenient use and low investment. It has been recognized and welcomed by customers since its listing. Fruit and vegetable cleaning sewage treatment equipment to remove organic pollutants and ammonia nitrogen mainly depends on the AO biological treatment process in the equipment. The working principle is that, due to the high concentration of organic matter in the sewage, the microorganisms are in anoxic state. At this time, the microorganisms are facultative microorganisms, and they convert the organic nitrogen in the sewage into NH3-N, and use organic carbon as an electron donor. The conversion of NO2-N, NH3-N into N2, and the use of organic carbon source and NH3-N to synthesize new cellular material, so the pool not only has a certain organic matter removal function, but also reduces the organic load of the subsequent aerobic tank to facilitate nitrification. The action is carried out, and relying on the higher concentration of organic matter present in the raw water to complete the denitrification, and finally eliminate the eutrophication of nitrogen. At the O level, since the organic matter concentration has been greatly reduced, a certain amount of organic matter is still decomposed into CO2 and H2O, and the autotrophic bacteria (nitrifying bacteria) use inorganic carbon generated by decomposition of organic matter or CO3 in the air as a nutrient source to treat sewage. The NH3-N in the conversion to NO2-N, NO3-N, the effluent portion of the O-stage pool is returned to the pool to provide an electron acceptor for the pool. Nitrogen contamination is eventually eliminated by denitrification.

Second, the process characteristics of fruit and vegetable processing sewage treatment equipment

1) The BOD load is high, the sludge biomass is large, the treatment efficiency is relatively high, and the influent impact load (hydraulic shock load and organic concentration shock load) has certain adaptability;

2) The processing time is short, and under the condition that the amount of treated water is the same, the equipment of the required device is small, and thus the floor space is small;

3) It can be operated intermittently. The biofilm has strong adaptability to intermittent operation. When it is parked for a long time, bacteria and protozoa can enter a dormant state. Once the environmental conditions improve, the microorganisms start to grow and metabolize again.

4) It is convenient to maintain and manage, and does not need to return sludge.

Third, the principle of fruit and vegetable processing sewage wastewater treatment equipment

1 adsorption. The aerobic microorganisms are mutually consolidated during the growth and reproduction of the filler to form a biofilm with a relatively large surface area and a high concentration, which can adsorb most of the organic pollutants in the water and reduce the concentration of the pollutants.

2 intake, decomposition. When the fruit and vegetable processing sewage wastewater treatment equipment continuously supplies air into the reactor, the aerobic microorganisms can take the adsorbed organic pollutants as nutrients into the body for metabolism, and part of it is used for its own growth and reproduction, and part of it is converted into Carbon oxide and water.

Fourth, the main features of fruit and vegetable processing sewage treatment equipment:

1. No sludge backflow, high removal efficiency.

2. Simple operation and convenient maintenance.

3, low noise, no smell.

4, long service life.
