Embodiment 1

[0026] Biological agent preparation process for car wash sewage treatment, including:

[0027] (1) adding sodium alginate, adsorption carrier and distilled water into the container for sterilization; the addition of the adsorption carrier is 30-50wt% of the total amount of granules, and the concentration of sodium alginate is 7-8wt%;

[0028] (2) Add bacterial cells to the sterilized solution, mix evenly, add dropwise to a calcium chloride solution with a concentration of 2-3 wt%, take it out after standing for 1-2 hours, and make granules.

[0029] Further, the adsorption carrier is activated carbon particles, the particle size of the activated carbon particles is 30-60 mesh, and the added amount of the activated carbon particles is 35-40 wt% of the total amount of the granules. The bacteria include one or more of Bacillus subtilis, Bacillus licheniformis, Actinomycetes, Rhizobacillus, Pseudomonas, Rhodococcus or Bacillus brevis. The content of live bacteria in the granules ...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that the structure of the biological treatment pool 4 is optimized in this embodiment, and the specific settings are as follows:

[0037] In the present embodiment, the concentration of sodium alginate is 8wt%, the concentration of calcium chloride solution is 3wt%, and the standing time is 2h; the addition of the adsorption carrier is 40wt% of the total amount of the granules, and the particle diameter of the activated carbon particles is 30-30wt%. 50 orders, the thalline only includes Rhizobium, and the content of live bacteria in the granule of the present invention is 1×10 9 ~1×10 12 cuf / g.

Abstract

The invention discloses a preparation process of a biological agent for car washing sewage treatment, and solves the problems that car washing sewage treatment in the prior art is relatively high in cost and relatively low in efficiency, and cannot be better and widely applied to sewage treatment of car washing water. The process comprises the following steps: (1) adding sodium alginate, an adsorption carrier and distilled water into a container for sterilization, wherein the addition amount of the adsorption carrier is 30-50wt% of the total amount of granules, and the concentration of the sodium alginate is 7-8wt%; and (2) dropwise adding the sterilized solution into a calcium chloride solution with a concentration of 2-3wt%, performing standing for 1-2 hours, and taking out the obtainedmaterial and preparing granules. The process has the advantages of high treatment efficiency, low cost and the like.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to a biological agent preparation process for car washing sewage treatment. Background technique [0002] With the rapid development of my country's economy, the number of motor vehicles has increased significantly, and the after-sales service industry of automobiles has also developed rapidly. Among them, the dust removal, cleaning and maintenance business of vehicles has developed rapidly. [0003] Water is the source of life and a key resource for human production and life. However, the shortage of water resources and serious water pollution are the current situation of water use in our country. The rational use of water resources and the control of water pollution have become the most concerned issues in modern society. At the same time, the vehicle cleaning industry consumes a lot of water. Taking Chengdu as an example, the annual water consumption for car washing exceeds 20 milli...
