Background
In the river dredging process, the traditional method is to use a high-pressure pump to convey high-pressure water to the river bottom to clean the river bottom. Thus, the sludge deposited on the bottom of the river inevitably spreads to soil the river. These sludges containing large amounts of sludge are typically returned to the sewage treatment site for treatment using sludge suction trucks or tankers, which are expensive. When water in a reservoir such as a swimming pool is retained for a long time, blue algae are generated, and the water in the reservoir becomes dirty. Therefore, the water in the tank is periodically subjected to a purification treatment. Since the conventional method is to exchange the water in the reservoir in full, it takes a long time and a considerable cost. In lakes in parks and the like, the lakes are seriously polluted by industrial discharged wastewater, domestic sewage and the like. The existing sewage treatment adopts physical methods which consume manpower and material resources, and adopts sewage treatment agents to carry out chemical treatment, but the cost is higher, and the treatment effect is not satisfactory.

Comparative example 2
Containing only hemp seeds, the procedure was identical to that of example 5.
The sewage treatment agent of the invention is adopted to carry out the following application tests:
example 6 the high efficiency sewage treatment agent system of example 5 was used to improve lake and pond water quality:
the pond in a certain village of Shanghai is square and round,the area is about 1200m2The maximum water depth is about 2.5m, domestic sewage of villagers is directly discharged into the pond through the sewage port without being treated, the water body in the pond is black and odorous, and the water quality is extremely poor. When the temperature is slightly higher, blue algae appears. The black and odorous water body makes residents fearful and the leisure facilities beside the pond become furnishings. In order to improve the ecological environment in the village, the pond is divided into three equal parts, the water body of the pond is treated by adopting the treating agents of example 5 and comparative examples 1-2, and 33 kg of sewage treating agent (about 30-40g/1 cubic of sewage) is added.
The military submachine boat is used as a carrier, and a propeller of the submachine boat is used as a power stirring tool, so that the medicament and the polluted water body are fully mixed, and the reaction efficiency is improved. After standing for 1-2 hours, pollutants with large specific gravity in the water body are condensed and settled, and pollutants with light specific gravity float on the water surface, so that solid-liquid separation is realized in a short time. The transparency of the treated water body is obviously increased, and the water quality is obviously improved.
The change conditions of the water quality before and after treatment are shown in table 1, the detection result of the treated water body is compared with the quality standard of the surface water, and most indexes of the treated water body reach the IV-class standard of the surface water.
TABLE 1 Water quality Change before and after treatment
As can be seen from the data in table 1:
1) the sewage treatment agent can obviously reduce the biochemical oxygen demand, the chemical oxygen demand and the permanganate index of the polluted water body, and the removal rates of the three indexes respectively reach 97.8 percent, 96.7 percent and 97.1 percent.
2) The sewage treatment agent can obviously reduce the total phosphorus in the water body, the total phosphorus content of the water body is reduced to 0.22 mg/L from 8.95mg/L before treatment, and the removal rate reaches 97.5%; the method also has a certain effect of removing the total nitrogen in the water body, the total nitrogen in the water body is reduced to 16.5mg/L from 34.5 mg/L before treatment, and the removal rate is 52.2%.
3) The sewage treatment agent can also effectively reduce heavy metals and toxic substances such as fluoride, cadmium, arsenic and the like in the water body.
4) The sewage treatment agent has small influence on the pH value of the water body, the pH value of the water body before treatment is 7.88, and the pH value of the water body after treatment is 7.25.
5) The transparency of the water body treated by the sewage treatment agent is obviously increased. The transparency of the pond water body before treatment is almost 0, and the transparency of the treated water body exceeds 1.2 m.
6) The concentration of the dissolved oxygen in the water body after treatment is obviously increased. The dissolved oxygen of the water body before treatment is almost 0, the dissolved oxygen of the water body after treatment reaches 3.0, and the increase of the dissolved oxygen creates conditions for the self-purification of the water body.
7) Comparison of comparative examples 1-2 with example 5 shows that the invention works with the combined action of the components.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
