The technical scheme of the invention belongs to the field of microbial fertilizer in the field of biological fertilizer. According to the national inspection, the qualified rate of microbial fertilizer random inspection is less than 60%. The main problems of product quality are that the number of effective bacteria does not meet the standard and the shelf life is too short. After the strains are prepared as microbial strain preparations, their survival ability decreases and their survival time is short during the preservation process. Therefore, in the production process, the activity of the strains is reduced, the production performance is weakened, the reproduction speed is slow, and the stress resistance is poor. The new bacterial strains provided by the invention and the microbial strain agent produced by the new technology scheme can very well solve the problems of reaching the standard of the strain number and prolonging the shelf life, which makes the present invention very important and meaningful.

The invention discloses a deep chemical wastewater treatment system which comprises a Fenton fluidized bed device, a flocculation and sedimentation device and a biological aerated filter device which are sequentially communicated with one another, wherein the Fenton fluidized bed device comprises a reaction tank body, a clapboard, multiple water distributors, granular catalyst packing, an effluent weir plate, a first water outlet pipe, a water inlet pipe, a return pipe, a circulating pump and a first dosing device; the clapboard divides the reaction tank body into a lower premixing chamber and an upper reaction chamber separator; the multiple water distributors are arranged on the clapboard; the effluent weir plate is arranged on the upper part of the reaction chamber; and the circulating pump and the first dosing device are arranged on the return pipe. According to analysis of the various existing wastewater treatment technologies, targeted research is performed by combining the problems such as complicated chemical wastewater matter structure and high treatment difficulty, and the Fenton fluidized bed technology and the biological aerated filter technology are ingeniously combined according to the economy principle in actual production, so that the advantages of the two technologies are synergistically matched with one another, and the problem that the chemical wastewater treatment does not reach the standard and the problem that the conventional equipment is high in operating cost are solved.
