Problems solved by technology

Existing repair agents are almost all formulated with chemical preparations. Although they have certain effects on the water quality of black and odorous water bodies, the water quality is difficult to meet the requirements of aquaculture. Moreover, with the residual bait and cultured products produced in...

Embodiment 1

[0023] Example 1: A black and smelly river, ammonia nitrogen (NH3-N): 23mg / L, total phosphorus (P): 1.06mg / L, chemical oxygen demand (COD): 110mg / L, transparency: below 10cm, stench Odor: strong, river sludge Color: black or grayish black. According to the treatment of 2000m per ton of mineral restoration agent 3 The dosage of the water body, the formula of the mineral restoration agent is 85% of natural zeolite powder, 5% of diatomaceous earth, and 10% of polyaluminum chloride. After adding for 5 days, the black odor and ammonia nitrogen (NH 3 -N): 1.8mg / L, total phosphorus (P): 0.2mg / L, chemical oxygen demand (COD): 48mg / L, transparency: crystal clear.

Embodiment 2

[0024] Example 2: The surrounding area of ​​a certain pond is a garbage dump site for many years. In summer, rainwater and nearby surface runoff gradually wash away the surrounding garbage mountains to form irregular ponds. The water body turns brown, emits a foul smell, and the transparency is almost zero. The garbage at the bottom of the pond continues to pollute Water body. COD in water: 350mg / L, ammonia nitrogen: 60mg / L, total phosphorus: 2.5mg / L. According to the treatment of 2000m per ton of mineral restoration agent 3 The dosage of the water body, the formula of the mineral restoration agent is 88% of natural zeolite powder, 4% of diatomaceous earth, and 8% of polyaluminium chloride. After adding for 10 days, the water quality reaches COD: 80mg / L, ammonia nitrogen: 4.8mg / L, Total phosphorus: 0.5mg / L. After the treatment is completed, the water in the pond will be discharged into the surrounding rivers.

Embodiment 3

[0025] Example 3: In a certain river channel, due to the sneaky discharge and dumping of pickling wastewater by surrounding factories, the water body and the bank slopes on both sides have turned reddish brown, with a pH of 2-3, ammonia nitrogen 52.5mg / L, COD 825mg / L, and waste acid pollution. Sediment pollution, heavy metal pollution seriously exceeded the standard. According to the treatment of 1500m per ton of mineral restoration agent 3 The dosage of the water body, the formula of the mineral restoration agent is 90% of natural zeolite powder, 5% of diatomite, and 5% of polyaluminium chloride. After 10 days of adding, the water quality reaches COD: 110mg / L, ammonia nitrogen: 4.5mg / L, total Phosphorus: 0.6mg / L. After treatment, the water environment is restored, the pH value is 7-8, the sandy layer is well sealed by the bottom mud, and the transparency of the water body is restored. After three months of maintenance, all indicators of water quality returned to normal.

Abstract

The invention provides a natural mineral repairing agent. The natural mineral repairing agent is prepared from the following main components of natural zeolite powder, kieselguhr and polymeric aluminum chloride. The natural mineral repairing agent provided by the invention takes natural minerals as the main components, the natural mineral repairing agent not only can be added in a dry powder form,but also can be used by adding water for dissolving, the operation is convenient, the natural mineral repairing agent is environment-friendly and cannot generate secondary pollution after use, a subduction function on bottom mud is obtained, desilting cost can be saved, the treatment effect is lasting, and recurrence is not easy; when the natural mineral repairing agent is used for treating fivekinds of surface water and aquaculture wastewater, pollutants such as COD (Chemical Oxygen Demand), ammonia nitrogen and total phosphorus in water can be rapidly reduced; the natural zeolite in the natural mineral repairing agent has very strong adsorption property on the ammonia nitrogen and is capable of removing 90 percent or above of ammonia nitrogen in the water, so that the natural mineral repairing agent has a very good purifying effect aiming at the water with overproof ammonia nitrogen.

Description

technical field [0001] The invention belongs to the technical field of waste water purification treatment, and in particular relates to a natural mineral restoration agent. Background technique [0002] With the rapid development of modern society and the continuous improvement of people's living standards, a large amount of domestic sewage, agricultural irrigation water, domestic garbage, industrial wastewater, and surface runoff with a large pollution load directly flow into the water body, making the concentration of ammonia nitrogen in the river relatively high. In practical engineering applications, how to reduce the concentration of ammonia nitrogen in water bodies, how to increase aerobic and facultative anaerobic microorganisms in sludge, and digest sludge are the keys to improving water quality and comprehensively treating black and odorous water bodies. Existing repair agents are almost all formulated with chemical preparations. Although they have certain effects o...
