Problems solved by technology

However, as the country's environmental protection requirements become more stringent, the disadvantages of excessive use of chemical synthetic materials are highlighted, and the industry's attention is mainly due to two points. First, many chemical synthetic materials will bring obvious problems during production and use Secondary pollution; the second is that most of the chemical synthesis materials remain in the sludge, which will make sludge treatment more difficult and more complicated, which brings difficulties to the effective utilization of some sludge and also inhibits the recycling of many sludges in the industry Related business development

Abstract

The invention discloses a nano biological water purifying agent, which is obtained by leaching and filtering straw to obtain a filtrate and a filter residue, then concentrating the filtrate and mixing it with the filter residue and NaOH to obtain an alkalized feed liquid, and then roasting the high The mixed reaction of pore diatoms and alkalized feed liquid, and the immobilized bacterial liquid on the obtained high-porous diatoms, and finally mixed with polyaluminum chloride, polyferric chloride, and bentonite, and granulated to obtain the nano-biological water purifier . The nano-biological water purifying agent of the present invention attaches microorganisms to high-porous diatoms to make it have both the physical purification effect of flocculation and sedimentation and the biological purification effect, thereby achieving the purpose of purifying black and odorous water bodies and forming a natural ecological cycle.

Description

technical field [0001] The invention belongs to the field of environmental protection water purification, and in particular relates to a nano biological water purification agent. Background technique [0002] Traditional water purification materials usually refer to various chemical coagulation and flocculants used in the treatment, commonly used are some chemical synthetic materials such as polyiron, polyaluminum, and polymers. However, as the country's environmental protection requirements become more stringent, the disadvantages of excessive use of chemical synthetic materials are highlighted, and the industry's attention is mainly due to two points. First, many chemical synthetic materials will bring obvious problems during production and use Secondary pollution; the second is that most of the chemical synthesis materials remain in the sludge, which will make sludge treatment more difficult and more complicated, which brings difficulties to the effective utilization of s...
