Efficient ecological type sewage and sludge treating agent and preparation method thereof

Abstract

The invention relates to an efficient ecological type sewage and sludge treating agent and a preparation method thereof. A flocculant X consists of sodium carboxymethyl cellulose, polyferric sulfate and sodium bentonite with the weight ratio of 2:7:1; and a coagulant aid Y consists of starch, 2nd generation polyamide-amine, sodium hydroxide and ammonium persulfate with the weight ratio of 10:8:2:0.05. The invention overcomes the defects that the production process of multi-generation PAMAM dendritic polymer needs to be repeated many times, and the cycle time of each generation is overlong, which seriously affects the production process and greatly reduces the production efficiency, so the contamination control enterprises can not apply the multi-generation PAMAM dendritic polymer. The invention does not have the defects of high amide monomer residue in wastewater treatment by polyacrylamide and low production efficiency of the 4th generation polyamide-amine dendritic polymer, greatly increases the production efficiency, and enables the treating agent to have handleability and contamination removal and control effects.

Description

technical field The invention relates to the field of sewage treatment, in particular to a high-efficiency ecological sewage and sludge treatment agent suitable for waste water treatment and sludge dehydration and a preparation method. Background technique At present, the implementation of emission reduction makes sewage treatment face two arduous tasks. One is the upgrading of discharge water standards, and the other is that sludge treatment has been included in the tasks of sewage treatment. It is required that the sludge generated after sewage treatment must be reduced and treated in a harmless manner, and resource-based treatment is advocated. Sewage treatment chemicals and sludge treatment dehydrating agents have been generally used in two categories, one is inorganic polymer aluminum salts and iron salts, and the other is organic polymer polyacrylamide. The implementation of emission reduction has made enterprises increase the reuse of reclaimed water, leading to an ...

Problems solved by technology

In addition, this technical document also introduces that the preparation time of the half-generation polyamide-amine needs 24 hours, and so repeatedly, the production process of the 4th generation PAMAM dendrimer needs to be repeated many times and the cycle time of each generation is too long, which seriously affects the production process and makes The production efficiency is greatly reduced, making it impossible for pollution control enterprises to apply
