Embodiment 1
[0055] Embodiment 1 Mustard mustard wastewater treatment method
[0056] See the flow chart of mustard wastewater treatment process figure 1 , the specific method or process is as follows.
[0057] Processing steps:
[0058] 1) Mustard mustard wastewater enters the grid adjustment tank first, and the impurities carried in the wastewater are removed through the grid. At the same time, the pH value of the wastewater is stabilized between 8.0 and 8.5 by adding acid and alkali to ensure the efficient operation of subsequent biochemical treatment.
[0059] 2) The uniformly adjusted waste water is regularly input into the HEB dephosphorization pool by the automatic control system. Powdered activated carbon is used as the carrier in the dephosphorization pool. The amount of carrier is 12% (volume ratio) of the effective volume of the HEB dephosphorization pool. The input amount is 6% of the powdered activated carbon volume. Utilizing the efficient cell synthesis function of HEB co...
Embodiment 2
[0078] Embodiment 2 cost comparison
[0079] The investment cost of wastewater treated by the mustard mustard wastewater treatment system disclosed in CN105254036A is compared with the HEB composite biological preparation mustard wastewater treatment system of the present invention. The results are shown in Table 2 below.
[0080] Table 2 Cost comparison between mustard mustard wastewater treatment system of the present invention and CN105254036A mustard mustard wastewater treatment system
[0081]
[0082]
[0083] Show from the data of table 2, HEB composite biological preparation mustard mustard wastewater treatment system of the present invention compares with the mustard mustard wastewater treatment system disclosed by CN105254036A, no matter from the use of land resources, total investment or from the aspects of operating costs and labor costs, the present invention The technology of CN105254036A is obviously better than that of CN105254036A.
