Embodiment 1

[0026] A composite biological water purifier, its formula is: 30 parts of modified porous natural stone particles, 25 parts of air oxidation iron removal filter drying residue and 5 parts of microbial flora.

[0027] The preparation method of this composite type biological water purifying agent is:

[0028] (1) Preparation of modified porous natural stone particles: take the modified porous natural stone particles, add concentrated sulfuric acid according to 30% of the weight of the porous natural stone particles, wherein the concentrated sulfuric acid is best added dropwise, after fully stirring and cooling for later use ;

[0029] (2) Air oxidative deironing and filtering dry slag, when using calcium oxide as a neutralizing agent to carry out air oxidative deironing by the soot leaching solution and / or zinc concentrate leaching solution of the wet zinc smelting plant, the obtained air oxidative deironing residue enters the filter, Made after drying. The air oxidation deiro...

Embodiment 2

[0033] A compound biological water purifying agent, its formula is: 40 parts of modified porous natural stone particles, 15 parts of air oxidation iron removal filter drying residue and 12 parts of microbial flora.

Abstract

The invention discloses a composite biological water purifying agent, which is prepared from the following components in parts by weight: 30-60 parts of modified porous natural stone particles, 10-25 parts of air oxidation iron removal filtering and drying slag and 5-15 parts of microbial flora, wherein the granularity of the modified porous natural stone particles and the air oxidation iron removal filtering and drying slag is 60-200 meshes; the microbial flora is attached to the modified porous natural stone particles and the air oxidation iron removal filter in a spraying or infiltrating manner; the modified porous natural stone particles are prepared by adding concentrated sulfuric acid into porous natural stone particles for curing, stirring and cooling; wherein the air oxidation iron removal filtering and drying slag is prepared by filtering and drying air oxidation iron removal slag when air oxidation iron removal is carried out on smoke leachate and/or zinc concentrate leachate of a zinc hydrometallurgy plant by taking calcium oxide as a neutralizer. The composite biological water purifying agent fully utilizes various resources, the raw materials are easy to obtain, the cost is low, and the prepared composite biological water purifying agent is stable in performance, good in purifying effect and easy to industrially popularize and apply.

Description

technical field [0001] The invention relates to the technical field of water body purification, in particular to a composite biological water purifier and a preparation method thereof. Background technique [0002] With the rapid development of social economy, human production and life discharge a large amount of waste water rich in organic matter such as nitrogen and phosphorus and various pollutants. If the sewage is discharged directly into the land and rivers without treatment, it will cause serious damage to rivers, farmland, and reservoirs. Natural water bodies such as coastal waters and coastal waters are polluted to varying degrees, causing heavy losses. Therefore, the prevention and treatment of water pollution has become a major problem to be solved urgently. [0003] Traditional processing methods have been difficult to meet the higher requirements at this stage in terms of performance stability, economic applicability and industrial application.
