Abstract

The invention discloses deodorizing composite biological stuffing special for dyeing and finishing wastewater treatment and a preparing method thereof. The stuffing comprises a component A and a component B. The mass ratio of the component A to the component B is 3:(6-8); the component A is prepared from dried sludge, converter slag, coal ash and clay, and the mass ratio of the dried sludge to the converter slag to the coal ash to the clay is (5-8):(5-7):(2-3):(3-5); the component B is prepared from, by mass, 10-20% of bark powder, 5-20% of saw dust, 50-60% of calcium carbonate and 20-30% of adhesive. The component A is prepared at first and then mixed with the component B to obtain the stuffing. The stuffing provides good adhesion space for growth of microorganisms, and provides a stable survival environment for growth of the microorganisms. Compared with inorganic stuffing like volcanic rock and natural or manual organic stuffing such as bark and synthetic resin, the stuffing has the advantages of being low in production cost, better in effect, stable in continuous use time, and beneficial for application to industrialized biological filter tank deodorization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a special deodorizing composite biological filler for printing and dyeing sewage treatment and a preparation method thereof. Background technique [0002] During the operation of the printing and dyeing sewage treatment plant, treatment units such as grilles, regulating tanks, hydrolytic acidification tanks, and A / O pools will generate a large amount of odorous gases. Once these odorous substances diffuse through the atmosphere, they will affect the air quality and ecological environment of the adjacent areas. and seriously affect people's health. The clean treatment of malodorous gas will be one of the important links of industrial sewage and urban sewage treatment. It is an important part of building a civilized, harmonious and hygienic society, and an effective measure to reduce the spread of diseases and protect groundwater sources. [0003] The malodorous gas in t...
