Embodiment Construction

[0015] A new type of sewage treatment method, characterized in that the specific steps are: input the sewage into the water collection and adjustment tank, then input the sewage in the water collection and adjustment tank to the coagulation and sedimentation tank, and enter the coagulation and sedimentation sewage into the CASS tank, Add Chinese medicine treatment agent in the CASS pool, and described Chinese medicine treatment agent comprises the following compositions of mass fraction: Cortex Phellodendri 50-150 parts, Dan Nanxing 100-250 parts, ginger 10-20 parts, licorice 2-15 parts, coptis 20-20 parts. 35 parts; the sewage treated by the CASS tank passes through the biological filter tank, and finally the treated water is obtained. The CASS pool is connected with a fan, and when the sewage enters the CASS pool, the fan blows the air to the CASS pool. The sludge in the CASS tank is subjected to sludge reflux treatment, and then the sludge in the CASS tank is input into the...

Abstract

The invention belongs to the technical field of environmental protection, and in particular relates to a novel sewage treatment method. The method comprises the following steps: inputting sewage into a water collection and regulating tank; inputting the sewage in the water collection and regulating tank into a coagulating sedimentation tank; leading the sewage which is subjected to coagulating sedimentation to flow into a CASS (cyclic activated sludge system) tank, and adding traditional Chinese medicine treatment agents consisting of the following components in parts by mass: 50-150 parts of cortex phellodendri, 100-250 parts of arisaema cum bile, 10-20 parts of raw ginger, 2-15 parts of liquorice, and 20-35 parts of coptidis rhizoma, into the CASS tank; leading the sewage treated in the CASS tank to flow through a biofilter tank to obtain the treated water. The method has the advantages that the traditional Chinese medicine treatment agents are added into the CASS tank, and harmful substances cannot be generated in the whole process because the traditional Chinese medicine treatment agents are pure natural substances.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a novel sewage treatment method. Background technique [0002] Activated sludge method is the main body of biological treatment of organic wastewater, but there are still some shortcomings that cannot be ignored: poor adaptability to impact load, easy sludge bulking, large area of ​​treatment structures, high capital investment and operating costs, and complicated management etc., there are existing patents for improving sewage treatment methods. For example, the patent application number is 201110115092, and the patent application date is May 5, 2011. The technical solution is: the invention discloses a method for treating papermaking wastewater by using a curved screen, which includes the following steps: (1) using a dehydrator to dehydrate the papermaking slurry to be treated to obtain the papermaking wastewater to be treated; (2) The papermaking wastewater t...
