Embodiment 1

[0020] The formula weight ratio is as follows:

[0021] Glucose 91.19%,

[0022] Ammonium chloride 6.99%,

[0023] Calcium phosphate 1.82%,

[0024] Before commissioning, the concentration of glucose in the biochemical pool was added to 700 mg per liter, the concentration of ammonium chloride was added to 53.66 mg per liter, and the concentration of calcium phosphate was added to 13.97 mg per liter.

[0025] The debugging method is as follows:

[0026] Step 1. Put glucose, ammonium chloride, and calcium phosphate into the biochemical pool injected with domestic sewage according to the percentage of the formula, and mix them evenly;

[0027] Step 2. Turn on the blower to blow air into the biochemical pool. The standard is: the dissolved oxygen in the biochemical pool is maintained at 2-3 mg per liter of sewage. After 12 hours, turn off the blower and let it stand for 4 hours. Turn on the blower for 10 hours. After 10 hours Stop for 3 hours, then turn on the blower for 8 hou...

Abstract

The invention provides a biochemical regulation method for domestic sewage treatment. A formula adopted by the method comprises 91.19% of glucose, 6.99% of ammonium chloride and 1.82% of calcium phosphate, and the components of the formula are added to make the concentration of glucose in a biochemical tank be 700-900 mg/L, the ammonium chloride concentration be 53.66-68.99 mg/L and the calcium phosphate concentration be 13.97-17.96 mg/L. The method comprises the following steps: 1, adding the glucose, ammonium chloride and calcium phosphate, and performing mixing to reach uniformity; 2, turning on a blower to blow air into the biochemical tank in order to make the concentration of dissolved oxygen in the sewage be 2-3 mg/L, turning off the blower 12 h later, standing the obtained sewage for 4 h, turning on the blower for 10 h, standing the sewage for 3 h, turning on the blower for 8 h, and standing the sewage for 3 h; 3, discharging the obtained supernatant, and detecting the concentration of pollutants in the supernatant; and 4, marking the above steps as one cycle, continuously performing the steps for six cycles, and adding the components before every cycle to make the glucoseconcentration be 700-900 mg/L, the ammonium chloride concentration be 53.66-68.99 mg/L and the calcium phosphate concentration be 13.97-17.96 mg/L, wherein the whole process is carried out for 240 h.The sewage treated through the method can reach national first-level B standards, and the method saves time, energy and expenses.

Description

technical field [0001] The invention relates to a debugging method for sewage treatment, in particular to a biochemical debugging method for domestic sewage treatment. Background technique [0002] Domestic sewage treatment must first carry out biochemical debugging of water treatment. The traditional debugging method takes 60 to 180 days or even longer to meet the national standard. There are problems of time-consuming, laborious and money-wasting. Due to the long commissioning time of domestic sewage treatment, it has brought various troubles to the water treatment work and has become a difficult problem in the water treatment work. Contents of the invention [0003] The purpose of the present invention is to provide a biochemical debugging method for domestic sewage treatment, the debugging time is only 240 hours, the time is short, the effect is good, and various expenses for water treatment work are reduced. [0004] The invention includes turning on the blower to bl...
