New combined potato starch wastewater treatment equipment

  [integration] potato starch sewage treatment equipment   The integrated potato starch wastewater treatment equipment has the advantages of low investment, small land occupation and low operation cost, and can effectively remove high concentration pollutants from starch wastewater

Potato starch sewage source:
Potato starch wastewater is the waste liquid produced in the process of producing starch with potato as raw material
It is also known as potato starch wastewater
It is a highly polluted wastewater with COD content of more than 10000mg/l
If it is discharged directly without treatment, it will cause anoxia in the environmental water body, suffocate aquatic organisms, and bring great harm to the environment
There are thousands of potato starch processing plants in China
The annual processing capacity of potato is nearly 3million tons
The production of starch reached more than 400000 t&\8943;
Potato starch production enterprises discharge more than 8 million tons of wastewater annually
Among them, washing wastewater is more than 4 million tons
More than 2
5 million tons of starch extract and more than 1
5 million tons of protein solution (process wastewater)

Principle of integrated potato starch sewage treatment equipment:
Potato starch wastewater treatment process:
Potato starch wastewater + mechanical grid regulating tank + defoaming tank + primary sedimentation tank + collecting tank + air flotation machine + intermediate tank +uasb+ stripping tank + primary contact oxidation tank + anoxic tank + secondary contact oxidation tank + coagulation sedimentation tank + effluent
Functions of each processing unit:
Mechanical grille: remove coarse suspended solids, avoid sewage pump blockage, and ensure the normal operation of the whole sewage treatment system
Regulating tank: regulating water quality and quantity
Defoaming pool: remove foam like substances in wastewater by adding defoaming agent
Primary sedimentation tank: use gravity difference to remove part of suspended solids
Collecting tank: collect the effluent from primary sedimentation tank, and pump is set in the tank to lift it into the air flotation machine
Air flotation machine: use small bubbles or tiny bubbles to make the small impurities in the wastewater with a specific gravity close to that of water surface
Intermediate water tank: collect the effluent from the air flotation machine, and pump is set in the tank to lift it into the UASB reaction tank
UASB reaction tank: under the action of anaerobic microorganisms, complete anaerobic reaction is carried out to convert organic matter into water, methane and carbon dioxide, and the gas is collected through the three-phase separator
Stripping tank: the harmful gases NH3 and H2S contained in the anaerobic effluent are released through aeration in the tank
Primary biological contact oxidation tank: utilize the metabolism of aerobic microorganisms to decompose organic pollutants in wastewater into low-energy sludge such as carbon dioxide and water for stabilization, and utilize the metabolism of nitrifying bacteria to convert ammonia nitrogen into nitrate
Anoxic tank: utilize the metabolism of denitrifying bacteria to convert nitrate into nitrogen for stabilization, and then remove ammonia nitrogen from wastewater
Secondary biological contact oxidation tank: further remove organic matters in Wastewater
Coagulation sedimentation tank: add coagulant into the sewage through the dosing system, mix it evenly with the water through the mixing system, and then remove the flocs through sedimentation
Characteristics of integrated potato starch sewage treatment equipment:

After sales service of integrated potato starch sewage treatment equipment:
Our company has set up a professional after-sales service team for installation, training, warranty, emergency response and return visit
Our principle is “ Quick, accurate, attitude ”, Solve equipment faults for customers at the fastest speed

Installation: after the production of integrated sewage treatment equipment is completed, we will ship the equipment to the customer's location according to the contract requirements
At the same time, we will send professional research integrated sewage treatment equipment engineers to the project site to guide the installation
After the installation is completed, we will conduct commissioning until the effluent meets the standard

Training: after the completion of the project, we will carry out technical training for the user's operators, including the working principle, process flow, daily operating procedures, common troubleshooting, etc
of the sewage treatment system until the church

Warranty: after the completion of the integrated sewage treatment equipment, we will provide a one-year free warranty period for the normal operation of the equipment
During the warranty period, technical service support will be provided to users free of charge
After the expiration of the warranty period, engineering maintenance services and equipment overhaul will only be charged at cost

Response to sudden failure: during the warranty period, when the operation and management personnel of the integrated sewage treatment equipment cannot eliminate the failure, after receiving the user's failure notice, our company will give an emergency plan within 2 hours, and the personnel in the province (48 hours outside the province) will arrive at the site to deal with the failure within 24 hours

Return visit: during the free warranty period, we will make an irregular return visit to assist the operation and management personnel of the integrated sewage treatment equipment to do a good job of the integrated sewage treatment equipment
