Problems solved by technology

However, when the microbial content in the sewage is small and the activity is insufficient, it will lose its ability to decompose organic matter, reduce the decomposition speed, and it is difficult to obtain a high decomposition efficiency. This is why the effect of using biological technology to treat sewage is not obvious.

Embodiment 1

[0042] In this example, the water quality of a water playground is treated. The water indicators before treatment are: total phosphorus<0.28mg / L, total nitrogen<1.3mg / L, arsenic<0.08mg / L, lead<0.045mg / L , which are the four types of surface water environmental quality.

[0043] The specific processing method is as follows:

[0044] A. Put biocidal disinfectant in the sewage, the weight of the biocidal disinfectant is 0.01% of the sewage weight, and stir for 60 seconds;

[0045] B. Put biologically active water purifying agent in the sewage of step A. The weight of this biologically active water purifying agent is 0.01% of the sewage weight. After the stirring treatment, the middle water of the upper layer and the flocculated sediment of the lower layer are obtained;

[0046] C, reusing the middle water in the middle layer obtained in step B to send water to the circulation system;

[0047] D. Regularly remove the flocculated sediment in the lower layer obtained in step B, an...

Embodiment 2

[0068] In this example, pond water in a certain park is treated. The water indicators before treatment are: total phosphorus<0.30mg / L, total nitrogen<1.5mg / L, arsenic<0.09mg / L, lead<0.05mg / L, which is Four types of water quality for surface water environmental quality.

[0069] The specific processing method is as follows:

[0070] A, put biological bactericidal disinfectant in sewage, the input weight of this biological bactericidal disinfectant is 0.1% of sewage weight, stir for 10 seconds;

[0071] B. Put biologically active water purifying agent in the sewage of step A. The weight of this biologically active water purifying agent is 0.1% of the sewage weight. After the stirring treatment, the middle water in the middle layer and the flocculation sediment in the lower layer are obtained;

[0072] C, reusing the water delivery circulation system in the middle layer gained from step B;

[0073] D. Regularly remove the flocculated sediment in the lower layer obtained in step...

Embodiment 3

[0094] In this example, the sewage of a bathing place is treated. The water indicators before treatment are: total phosphorus<0.26mg / L, total nitrogen<1.1mg / L, arsenic<0.07mg / L, lead<0.04mg / L, which is Four types of water quality for surface water environmental quality.

[0095] The specific processing method is as follows:

[0096] A, put biological bactericidal disinfectant in sewage, the input weight of this biological bactericidal disinfectant is 0.05% of sewage weight, stir and process for 30 seconds;

[0097] B. Put biologically active water purifying agent in the sewage of step A, the throwing weight of this biologically active water purifying agent is 0.05% of sewage weight, after stirring treatment, get middle water in the middle layer, flocculated sediment in the lower layer;

[0098] C, reusing the middle water in the middle layer obtained in step B by sending the water circulation system;

[0099] D. Regularly remove the flocculated sediment in the lower layer ob...

Abstract

The invention provides a method for treating sewage into reclaimed water by active organisms. The method comprises the following steps: throwing a biological antiseptic disinfectant in sewage, stirring for 10 to 60 seconds, throwing a biological activity purifying agent in the sewage, stirring to obtain recycled water on the upper layer and flocculent settling matters on the lower layer, sending the recycled water on the upper layer to a water circulating system for reuse, periodically discharging the flocculent settling matters on the lower layer, and using the flocculent settling matters as greening fertilizers. Through the addition of the biological activity purifying agent, the leading role of beneficial microorganisms is highlighted, and the capability of the beneficial microorganisms in eating a great number of nutrient substances is enhanced greatly, so that the propagation and the growth of the beneficial microorganisms are accelerated, harmful bacteria in raw wastewater are extinguished quickly due to shortage of food, organic matters in water are absorbed and degraded quickly while the propagation of the beneficial microorganisms is accelerated, lots of impurities in water are absorbed through mucous layers and the capsule structures on the surfaces of the cells of the beneficial microorganisms, and finally the sewage is purified quickly to become recycled water.

Description

[0001] technical field [0002] The invention relates to a sewage treatment method, in particular to a method for treating sewage into reclaimed water by active organisms, and belongs to the technical field of sewage treatment. Background technique [0003] The healthy water cycle in cities and towns is divided into three levels. The first level is the reclaimed water cycle of water users, the second level is the recycled water cycle of sewage treatment plants, and the third level is the water intake cycle of rivers and lakes. Only by planning water use and formulating a sewage treatment plan according to the above-mentioned three-level water cycle can scientific, reasonable, efficient and water-saving be realized. Sewage treatment stations established in relatively large water users can use the treated and recycled reclaimed water for their internal greening, sanitation, landscape, production, etc., which can improve the efficiency of water recycling, and reclaimed wate...
