Description

An integrated aquatic product processing water treatment system

technical field

The invention relates to the field of water treatment, in particular to an integrated aquatic product processing water treatment system.

Background technique

In the process of aquatic product processing, especially in the process of fishmeal production and initial processing of aquatic products, the wastewater contains a large amount of pollutants, which leads to the increase of COD, ammonia nitrogen and other indicators in the water body, so that the discharge does not meet the standard. In the current aquatic product processing water treatment system, larger manufacturers use large-scale water treatment, and after treatment, the water is discharged into the municipal pipe network or directly up to the standard. Most of the other small manufacturers adopt simple treatment methods. The wastewater is deposited in a sedimentation tank, and then the supernatant is simply treated, and charges are charged according to the concentration of pollutants, and then it is discharged after unified treatment downstream. In this way, the wastewater discharged from the sedimentation tank still contains a large amount of pollutants, which increases the processing pressure on the municipal sewage system. At the same time, if the concentration of pollutants can be reduced after treatment, the cost of sewage discharge of enterprises will also be reduced. At the same time, considering that ordinary sewage treatment facilities occupy a large area, if the water treatment units can be integrated and operated in an integrated manner to reduce the floor space, the existing factory resources can be effectively utilized and the treatment can be achieved at the same time.

Example

The mixed waste water 1 is discharged into the mixed waste water tank 2, and then the waste water in the mixed waste water tank 2 is discharged into the reservoir 3, and then flows into the adjustment tank I4, and acidic substances such as sulfuric acid can be added to the adjustment tank I4, etc. After acidification, it flows into the flocculation tank 5 and the filter bag I6. A part of the wastewater is treated by the sludge outgoing device I7, and the remaining part enters the core reactor 8, and the catalyst and oxidant are added to the core reactor 8, and the reaction is complete. Then it flows into the wastewater collection device I9, and then enters the RO membrane reverse osmosis pure water treatment system 10, and then diverts the wastewater treated in the previous step into the parameter detection device 11 for detection, and is collected by the wastewater detection and collection device 12. Preliminarily unqualified wastewater flows into wastewater collection device II13, and then flows back to wastewater collection device I9 through another pipeline, and repeats the operation until it is initially qualified. Alkaline substances such as sodium hydroxide can be added, and after alkalization, it flows into the filter bag II15. A part of the waste water is treated by the sludge outgoing device II16, and the remaining part enters the regular monitor 18, which is monitored and collected by the waste water. The device 19 collects the waste water that has passed the monitoring and is directly discharged into the outside world through the municipal sewage pipe network 17, and the unqualified waste water is then returned to the waste water collection device I9 through another pipeline, and the operation is repeated until it is qualified.

Since the PH, COD, ammonia nitrogen, salinity and other values contained in different wastewaters are also different, the PH, COD, ammonia nitrogen and other values in the water also change significantly after passing through the water treatment system. The following are typical fishmeal wastewater and squid wastewater. The numerical table of PH, COD, ammonia nitrogen, salinity, etc. contained in the water treatment system (Table 1 and Table 2, respectively) and the numerical table of PH, COD, ammonia nitrogen and the like in the water after passing through the water treatment system (Table 3):

Table 2

table 3

It can be seen from the table that the PH, COD, ammonia nitrogen, salinity and other values contained in the typical fishmeal wastewater and squid wastewater are relatively high before entering the water, which cannot meet the discharge requirements. After treatment, the content of the effluent is obviously much lower than that before the influent, which has reached the index of sewage discharge, thus avoiding the problem of water pollution.
