Problems solved by technology

Especially when the pollutants in the water cannot be completely separated from the water, on the one hand, it will directly affect the transparency of the water, thereby hindering the photosynthesis of aquatic organisms and plants in the water body, affecting the healthy growth of aquatic organisms, microorganisms, plants, etc., and ultimately destroying the ecological balance of the water body On the other hand, the separated pollutants are difficult to collect and utilize due to sinking into the bottom of the water, and will cause secondary pollution of the water body again. At the same time, the gradual accumulation of sinking pollutants will affect the water depth and change the original water ecological environment.

Embodiment 1

[0033] In this embodiment, the sewage of a certain river is purified. The indicators of the river water before treatment are: total phosphorus<0.28mg / L, total nitrogen<1.3mg / L, arsenic<0.08mg / L, lead<0.045mg / L L, for the four types of water quality of surface water environment quality.

[0034] The specific processing method is as follows:

[0035] 1. In the upper reaches of the river, put in the artificially cultivated cyanobacteria solution with a cyanobacteria dry matter content of 0.5g / L, and the flow rate of the cyanobacteria solution is 1% of the water flow;

[0036] 2. Put in the active biological water purifier at the same time as the cyanobacteria liquid, the flow of the active biological water purifier is 0.1% of the water flow,

[0037] 3. Salvage and collect the flocs floating on the river surface in the downstream of the river, and at the same time detect the indicators of the downstream river water: total phosphorus <0.1mg / L, total nitrogen <0.5mg / L, arsenic <0....

Embodiment 2

[0057] The present embodiment purifies the sewage of a certain river. There is a pond where blue-green algae explodes near the river. The dry matter content of blue-green algae in the blue-green algae liquid in the pond is 3g / L. The index of the water before the treatment of this river is as follows: Total phosphorus < 0.30mg / L, total nitrogen < 1.5mg / L, arsenic < 0.09mg / L, lead < 0.048mg / L, which is the fourth category of surface water quality.

[0058] The specific processing method is as follows:

[0059] 1. In the upstream of the river, the cyanobacteria solution with a dry matter content of 3g / L of cyanobacteria introduced into the pond through the pipeline, and the flow rate of the cyanobacteria solution is 0.1% of the water flow;

[0060] 2. Add active biological water purifier while introducing cyanobacteria liquid, the flow rate of this active biological water purifier is 0.01% of the water flow,

[0061] 3. Salvage and collect the flocs floating on the river surface...

Embodiment 3

[0073] In this embodiment, the sewage of a certain pond where cyanobacteria broke out is purified. The cyanobacteria dry matter content of the cyanobacteria liquid in the northwest position in the pond is 4g / L, because the pond also has water flow into the pond, and the water flow into the pond is also sewage. Therefore, at the same time, it is necessary to purify the water flow into the pool. Before the treatment, the water flow indicators at the entrance of the pool are: total phosphorus <0.25mg / L, total nitrogen <1.1mg / L, arsenic <0.06mg / L, lead <0.055mg / L , which is the fourth category of surface water quality; the indicators of pond water before treatment are: total phosphorus <0.45mg / L, total nitrogen <2.5mg / L, arsenic <0.15mg / L, lead <0.15mg / L, for Severely polluted water quality.

[0074] The specific processing method is as follows:

[0075] 1. In the upstream of the water flow into the pond, introduce the cyanobacteria solution with a cyanobacteria dry matter conten...

Abstract

The invention provides an ecological water treatment method. By adding blue algae liquid and an active biological water purifying agent into rivers, lakes or ponds, the capability of grabbing a large quantity of nutrients for beneficial microbes is enhanced, and propagation and growth of the beneficial microbes are accelerated, so that the beneficial microbes become pilot active microbes and can quickly absorb and degrade organic substances in the water and inhibit other harmful microbes; and in the blue algae bacteria rising process, nitrogen, phosphorus nutrients, heavy metals and other suspended substances in the water are adsorbed and fixed to facilitate fishing and collection to form raw materials for efficient organic fertilizers, so that the consumption of fertilizers is reduced, the blue algae is changed into valuable and usefulness, good treatment of treating dirt with dirt is realized, the water becomes transparent and clear, healthy growth of aquatic organisms and plants in the water under full photosynthesis is facilitated, the ecological purification function of the water is quickly recovered, and the original ecological balance of the water is finally recovered.

Description

technical field [0001] The invention relates to a method for treating sewage, in particular to a method for ecologically treating water bodies, and belongs to the technical field of water treatment. technical background [0002] Purification of water bodies in river basins, lakes and ponds is a very difficult and complex system engineering. It is difficult to achieve the purpose of purification and achieve the ideal purification effect only with a single physical, chemical or biological method. Especially when the pollutants in the water cannot be completely separated from the water, on the one hand, it will directly affect the transparency of the water, thereby hindering the photosynthesis of aquatic organisms and plants in the water body, affecting the healthy growth of aquatic organisms, microorganisms, plants, etc., and ultimately destroying the ecological balance of the water body On the other hand, the separated pollutants are difficult to collect and utilize due t...
