Embodiment Construction

[0014] A kind of manufacture craft of the flocculant of processing printing and dyeing sewage of the present invention, comprises the steps:

[0015] Ⅰ) Preparation of EM bacteria liquid: take clean water and boil, boil for a while, cool to a temperature of 23-25°C, take 10,000 parts of cooled water, add 1,000 parts of brown sugar, 1 part of EM bacteria, pour into a container and stir well, Cover the lid, slightly open a line of seams, and carry out facultative fermentation. The room temperature of the production place is 23-25°C. After opening the lid on the 10th day, add 1000 parts of honey, and then cultivate for 5 days with facultative fermentation. A total of 15 days to complete; check the EM bacteria liquid, the pH of the EM bacteria liquid is less than 3.8, the color is light brown or yellowish brown, there is a strong sweet-sour smell or sour smell, and a large amount of gas is produced, which is a qualified product. The EM strain, whose English name is Effective Micro...

Abstract

The invention relates to a preparation process of a flocculant for treating dyeing wastewater and an application method of the flocculant. The preparation process comprises the following steps: I) preparing an EM bacterial solution, II) cultivating bacterial colonies; and III) uniformly mixing 20 parts of the EM bacterial solution prepared in the step I with 1 part of a diluent of a mixed strain of Nocardia corallina, Rhodospirillum and nitrobacterium prepared in the step II. According to the preparation process disclosed by the invention, the EM bacterial solution is adopted as a main body, the combination of the characteristic role of microorganism strains and the capabilities of purifying water and degrading organic pollutants, nitrogen and ammonia in water bodies of Nocardia corallina, Rhodospirillum and nitrobacterium based on the EM bacteria technology and the EM bacterial genus coexistence and growth law characteristic can play a synergistic role in water treatment, CODcr, BOD5 and SS can be reduced, the content of the mud in the water is decreased, the decomposition of nutrient salts and deodorization are achieved.

Description

technical field [0001] The invention relates to a flocculant for printing and dyeing sewage treatment, which belongs to the field of sewage treatment materials. Background technique [0002] At present, the inorganic and organic flocculants selected for water treatment in the environmental protection market; such as polyaluminum chloride, aluminum sulfate, ferrous sulfate, polymer polyacrylamide, etc., produce sediments after physical and chemical reactions to varying degrees and become a certain amount of sludge , the follow-up damage standardization treatment is required. Inorganic and organic flocculants are not only costly to add, but also the dosage is basically twice the concentration of the contaminated substrate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a kind of can effectively reduce CODcr, BOD 5 , SS index, a production process and application method of a flocculant for...
