Problems solved by technology

[0003] The existing sewage treatment method biological phosphorus removal is at the back end of biological nitrogen removal, and the biological phosphorus removal is not complete, so it needs auxiliary chemical phosphorus removal, so that the sludge is polluted again

Embodiment

[0041] Segmented water intake is divided into front section water intake and rear section water intake. The front section sewage enters the first sewage pool 2, and the rear section sewage enters the second sewage pool 3; the front section load is 0.3 to 0.45, and the rear section load is 0.1. The front section and the rear section The water inlet ratio is 3:1, and the second water inlet is to introduce the sewage from the first sewage tank into the second sewage tank; the water inlet ratio of the front section and the rear section is 3:1, and the dilution ratio is 1:4 to 1:6 ;Adjust the aeration rate, the average dissolved oxygen concentration in the front section is controlled from 1mg / L to 1.2mg / L, the backflow in the front section is controlled at 50% to 60%, the average dissolved oxygen concentration in the back section is controlled from 1mg / L to 1.6mg / L, and the backflow is controlled at 1mg / L to 1.6mg / L. Control at 50% to 60%; adjust the influent flow, the hydraulic ret...

Abstract

The invention discloses a continuous flow automatic domestic sewage treatment method. The method comprises the following steps: feeding water in stages; performing secondary water feeding; selecting a water inlet and distribution ratio and a dilution ratio; adjusting the aeration rate; and adjusting the water inlet flow. A first sewage tank is used for biological phosphorus removal, and then sewage treated by the first sewage tank is introduced into a second sewage tank, so that the concentration of phosphorus and nitrogen in the second sewage tank can be reduced, and the phosphorus and nitrogen can be biologically removed, so that full-biological nitrogen and phosphorus removal is realized, and secondary pollution caused by phosphorus removal by auxiliary chemical agents is avoided; and the sewage treatment equipment can stably and continuously operate by reasonably selecting the dilution ratio and the water inlet ratio.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a continuous flow automatic domestic sewage treatment method. Background technique [0002] Modern sewage treatment technology can be divided into primary, secondary and tertiary treatment processes according to the degree of treatment. Primary sewage treatment applies physical methods, such as sieving, sedimentation, etc., to remove undissolved suspended solids and floating substances in sewage. The secondary treatment of sewage is mainly the application of biological treatment methods, that is, the process of material transformation through the metabolism of microorganisms, to oxidize and degrade various complex organic substances in sewage into simple substances. Biological treatment has certain requirements on sewage water quality, water temperature, dissolved oxygen in water, pH value, etc. The tertiary treatment of sewage is based on the primary and seco...
