Problems solved by technology

These flocculants are widely used in wastewater treatment and downstream industrial processes. Inorganic water purifiers such as aluminum salts (aluminum sulfate, polyaluminum chloride, etc.), iron salts (ferric chloride, polyferric sulfate, etc.), organic synthetic polymer net Aqua is due to economy and high efficiency, practical application is the most, yet, it brings environmental protection and health problem again simultaneously: the one, its biodegradability is poor, the 2nd, its monomer or degradation product have toxicity (as acrylamide is carcinogen)
For areas with poor water resources, it is particularly important to purify industrial wastewater so that it can be recycled. Water purifiers are more and more widely used in the treatment of various water qualities. The secondary pollution caused by sex and the environment has also attracted more and more attention. For example, inorganic water purifiers and aluminum salts are added to the water body to make the Al in the water 3+ Increase will cause Alzheimer's disease; the addition of iron salts will make the water color darker, if there is sulfide in the water, it will form a mixture colloid, which is difficult to form precipitation
In addition, it is difficult to avoid the presence of acrylamide in the synthetic organic polymer water purifier (polyacrylamide). If it is added to the water body, the concentration of acrylamide in the water body will increase. Acrylamide is a highly toxic substance, which will cause harm to human health.

Abstract

An ecological water purification agent containing lily juice and application thereof belong to the technical field of environmental chemical industries. The ecological water purification agent containing the lily juice is characterized by comprising the following materials by weight percentage: 55-75% of the lily juice, 20-40% of organic acid, 1-6% of a surfactant and 1-5% of a flocculant. The ecological water purification agent containing lily juice and the application thereof use the lily juice as a carrier to compound a little chemical drug, thereby having the effects of deodorizing, sterilizing, efficiently flocculating, degrading harmful materials and the like. Organic pollutants can be quickly absorbed to be removed, heavy metal ions can be precipitated and simultaneously chemical oxygen demand and suspended matters in water can be eliminated. Solid-liquid separation effect of waste water is good, and removing rate of chromaticity and turbidity is high. The ecological water purification agent containing the lily juice is simple in processing method, small in equipment investment, low in prices, environmental-friendly, wide in application, safe in storage and application, free of secondary pollution and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of environmental chemical industry, in particular to an ecological water purifier containing lily juice and its application. Background technique [0002] Commonly used water purifiers at home and abroad include inorganic water purifiers and organic water purifiers. These flocculants are widely used in wastewater treatment and downstream industrial processes. Inorganic water purifiers such as aluminum salts (aluminum sulfate, polyaluminum chloride, etc.), iron salts (ferric chloride, polyferric sulfate, etc.), organic synthetic polymer net Aqua is due to economy and high efficiency, practical application is the most, yet, it brings environmental protection and health problem again simultaneously: the one, its biodegradability is poor, the 2nd, its monomer or degradation product have toxicity (as acrylamide is carcinogens). With the development of science and technology, it has been found that inorganic wat...
