A high-efficiency composite biological agent for the treatment of difficult organic wastewater

Abstract

The invention discloses an HEB compound biological preparation for high-difficulty organic wastewater treatment. The compound biological preparation comprises the following components in percentage by weight: 1% of yeast, 1% of fermented lactic acid bacteria, 1% of liquefied bacillus aceticus, 1% of denitrification alkali-producing bacteria, 1% of bacillus subtilis, 0.5% of Brevibacterium casei, 0.5% of Nitrosoccusnitrosus, 0.5% of Rhodopseudomonas palustris and 0.5% of Blastochloris. By putting the compound biological preparation into a high-difficulty organic wastewater treatment system, high-difficulty organic wastewater such as organic wastewater can be treated to meet the first class discharging standard in Integrated Wastewater Discharge Standard (GB8978-1996).

Description

technical field [0001] The invention belongs to the technical field of microorganism application for waste water treatment, and in particular relates to a composite biological preparation for treating difficult organic waste water. Background technique [0002] my country's environmental protection industry started relatively late, but has developed rapidly. At present, various wastewater treatment technologies and equipment manufacturing in the field of wastewater treatment have matured, and a large number of large-scale wastewater treatment plants have been built in various industries across the country. (station), and achieved good environmental and social benefits. At the same time, my country's environmental protection industry is also facing many serious problems. Due to the eagerness for quick success, a lot of manpower and material resources are spent on process improvement, equipment modification and optimization of microbial growth environment in the process of intr...

Problems solved by technology

At the same time, my country's environmental protection industry is also facing many serious problems. Due to the eagerness for quick success, a lot of manpower and material resources are spent on process improvement, equipment modification and optimization of microbial growth environment in the process of introducing environmental protection technology, but it plays a decisive role in biochemical treatment. Few people care about the microorganisms, so that AO method, AAO method, AOAO method, SBR method, CASS method, CAST method and many other sewage treatment processes have appeared one after another, and the patents and manufacturers of various fillers are too numerous to mention. However, there are still a considerable proportion of sewage treatment plants (stations) that cannot operate normally, especially in some difficult wastewater treatment fields. Most of the sewage treatment facilities that manufacturers spend huge sums of money on are not operating well. The cost is high, and the emissions cannot meet the standards. They still have to pay the excessive emission fees to the local environmental protection department, and some are even forced to stop production.
