Technique for preparing effervescence type coagulant used in treatment of landscape water pollution

Abstract

The invention discloses a manufacture process for an effervescence type coagulant used for handling scenic water pollution and relates to the technical field of environment protection and polluted water purification. The process is as follows; 5-30 percent of kaolin, 30-60 percent of zeolite and 10-65 percent of adjuvant are mixed, broken up and ground into powder; the powder is parched, mixed evenly and formed by pressing. The adjuvant consists of 5-10 percent of citric acid, 9-15 percent of NaHCO3, 3-5 percent of Na2CO3, 1-2 percent of PVP and 1-2 percent of CMS-Na, which are mixed evenly together. After the implementation of the invention, as the effervescence type coagulant is a platy preparation by uniformly mixing and pressing natural mineral materials(clay coagulant) with coagulation and auxiliaries (distingrants), the coagulant can automatically distingrate when being directly scattered in water and release the clay coagulant to achieve the coagulation purpose. When the coagulant is fed, no mechanical equipment needs for stirring, and no feeding equipment is required. The coagulant is suitable for various surface water bodies, generates no secondary pollution, and has good environment safety, simple manufacture, low cost, convenient use and good effect.

Description

technical field [0001] The invention relates to the technical field of environmental protection and purification of polluted water bodies, and is applied to the technical fields of ecological restoration of eutrophic rivers and lake water bodies and water quality improvement, and in particular is an effervescent coagulant used for controlling the pollution of landscape water bodies. Background technique [0002] With the rapid development of the national economy and the expansion of cities in the past ten years, many surface water bodies such as rivers and lakes in my country have suffered from varying degrees of pollution, and there is a tendency to continue to intensify. As an important pollution control and water quality improvement technology, coagulation has been successfully applied in many lakes and rivers' ecological restoration and ecological improvement projects.

AI Technical Summary

Problems solved by technology

In order to achieve good hydraulic conditions, when adding the coagulant (or flocculant), it must be stirred by mechanical equipment. On the one hand, the power consumption is high, and on the other hand, it is necessary to develop specific water for different landscape water bodies. Dosing equipment, the existence of the above problems greatly limits the application of coagulation in surface water treatment
