Embodiment Construction

[0015] An environmentally friendly sewage treatment method, characterized in that the specific steps are: input sewage into a water collection adjustment tank, then input the sewage in the water collection adjustment tank into a coagulation sedimentation tank, and enter the coagulation and sedimentation sewage into a CASS tank, Add Chinese medicine treatment agent in the CASS pool, and described Chinese medicine treatment agent comprises the following composition of mass fraction: 20-30 parts of cotyledon, 5-15 parts of licorice, 10-15 parts of Sophora flavescens, 50-150 parts of aloe; The sewage treated by the CASS tank passes through the biological filter tank and finally gets the treated water. 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 sludge tank, and the upper layer of cle...

Abstract

The invention belongs to the technical field of environmental protection, and in particular relates to an environment-friendly 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: 20-30 parts of viola inconspicua, 5-15 parts of liquorice, 10-15 parts of sophora flavescens, and 50-150 parts of aloe, 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 an environmental protection 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 pape...
