Embodiment Construction
[0033] A treatment method for sewage generated by sludge drying described in this embodiment, the process flow is as shown in the accompanying drawings:
[0034] (1) The sewage generated during the sludge drying process is filtered through the grid channel to remove large debris and then enters the raw water lifting well. The sewage is pumped to the pH adjustment tank. When it is acidic, the sodium hydroxide solution in the alkali tank is automatically injected into the pH adjustment tank, and the lye and sewage are mixed in the adjustment tank by air blowing from the contact oxidation tank for neutralization reaction, and the pH is adjusted and controlled at 7 to 7.5;
[0035] (2) The sewage after pH adjustment enters the water quality adjustment tank, where the sewage is mixed, and the water quality adjustment tank adjusts the subsequent sewage treatment water volume (stored in the pool when it does not reach the liquid level line, and flows out when it reaches the liquid lev...
