Embodiment 1

[0017] Example 1. A method for treating sewage with high-efficiency microbial cells. For an artificial lake in a city park, due to the lack of early supervision, the surrounding domestic sewage was discharged into the lake in large quantities, resulting in deterioration of the water body. The COD was about 189 mg / l and the total nitrogen was 24.0 mg / l, total phosphorus 0.8mg / l, PH value 8.1, more algae growth, transparency 0.1-0.2 meters; use the following raw materials, photosynthetic bacteria, lactic acid bacteria, yeast, cellulase, papain, amylase, lipase , the dosage of liquid photosynthetic bacteria, 5-12 grams per cubic meter of water, the dosage of activated lactic acid bacteria, 1-4 grams per cubic meter of water, the activated yeast, 4-8 grams per cubic meter of water, fiber Sulfase 0.1-0.8 grams, papain 0.5-0.9 grams, amylase 0.01-0.06 grams, lipase 0.01-0.07 grams.

[0018] In the sewage to be treated, first aerate to make the dissolved oxygen amount reach at least ...

Abstract

The invention relates to a method for treatment sewage, in particular to a method for effectively treating sewage by using both microbial cells and enzyme preparations, aiming at solving the problem of sewage treatment. The method comprises the following steps: treating the sewage by using photosynthetic bacteria, lactic acid bacteria, yeast bacteria, cellulase, papain, amylase and lipase for 20-30 days to obviously improve water bodies, then immediately restoring the biologic chains of the water bodies, putting submerged plants comprising waterweeds and the like, phytoplankton, pet fishes and shrimps, planktonic animals and the like in the water bodies for breeding, and gradually stabilizing the water bodies to achieve new ecological balance and remove pollution. The microbial cells and enzymes are combined to take a synergic effect, and then various pollutants can be thoroughly eliminated by the functions of the enzymes in the early decomposition and digestion of the microbial cells.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a method for jointly treating sewage with high-efficiency microbial cells and enzyme preparations Background technique [0002] Eutrophication of water bodies is the main cause of algal blooms. The nitrogen, phosphorus and organic carbon loads in the water body are high, and the accumulation exceeds the self-purification capacity of the water body itself, breaking the stable ecological balance in the water body, resulting in the rapid reproduction of algae and other plankton, the decrease of dissolved oxygen in the water body, and the deterioration of water quality. Creatures die in large numbers. Currently, for polluted rivers and still water bodies. The initial sewage treatment adopted extremely simple physical and chemical treatment facilities. The debris in the water was intercepted by structures such as grilles, and then flocculated and sedimented. The sewage was initially trea...
