Embodiment 1

[0018] A multi-purpose high-efficiency rural sewage treatment agent, the raw materials in parts by weight are: 15 parts of bacterial liquid of Bacillus subtilis, 15 parts of nano-zinc oxide particles with earthworm protease fixed on the surface, 40 parts of water hyacinth stem and leaf extract, polysilicic acid 8 parts of aluminum and iron; the Bacillus subtilis adopts the endogenous Bacillus subtilis YS-45 of citrus; the preparation steps of the bacterial liquid of the Bacillus subtilis are: first activate the Bacillus subtilis, and then use 5% volume percentage to Inoculate into the culture medium for expanded culture to obtain Bacillus subtilis bacterial liquid; the conditions for activation are: culture at 30°C for 24 hours; the conditions for expanded culture are: culture for 24 hours at 35°C; the medium used in activation and expansion For: 6 parts of soybean meal powder, 0.3 parts of molasses, KH 2 PO 4 2 parts, 92 parts of potato juice with a mass concentration of 20...

Embodiment 2

[0021] A multi-purpose high-efficiency rural sewage treatment agent, the raw materials in parts by weight are: 20 parts of bacterial liquid of Bacillus subtilis, 20 parts of nano-zinc oxide particles with earthworm protease fixed on the surface, 50 parts of water hyacinth stem and leaf extract, polysilicic acid 10 parts of aluminum and iron; the Bacillus subtilis adopts the endogenous Bacillus subtilis YS-45 of citrus; the preparation steps of the bacterial liquid of the Bacillus subtilis and the preparation steps of the stem and leaf extract of the water hyacinth are all the same as those in the examples 1 is the same.

[0022] Take domestic sewage from a certain place, first adjust the pH value of rural sewage to 7.5, then add 1 ml of the multi-purpose high-efficiency rural sewage treatment agent to each liter of rural sewage, and stir for 20 minutes to make the sewage treatment effect reach the national discharge Standards, greatly reducing the amount of sludge discharge, r...

Abstract

The present invention discloses a multi-purpose efficient rural sewage treatment agent and a sewage treatment method using the multi-purpose efficient rural sewage treatment agent, according to the invention, bacillus subtilis bacteria bacterial liquid is used for biological treatment, zinc oxide with nanoparticles earthworm protease immobilized on the surface are used for enzyme treatment, a water hyacinth stem and leaf extract is used for plant liquid adsorption treatment, a small amount of inorganic polymer flocculant is used for chemical treatment, by combination of a plurality of kinds of treatment, the cost is greatly reduced, and the treatment effect is improved; the treatment agent can effectively treat domestic sewage, the treatment effect can meet the national emission standards, the amount of sludge discharge is greatly reduced to achieve ecologicalization, reduction and reclamation of domestic sewage treatment; the domestic sewage pollution to ecological environment can be reduced, sewage suspended solid removal rate can reach 99.6%, BOD removal rate is 98. 2%, COD removal rate is 98.8%, chroma is 5, sludge amount is less, a sludge treatment system is not needed, and the multi-purpose efficient rural sewage treatment is free of secondary pollution, stable in treatment effect, nontoxic and environmentally-friendly.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a multi-purpose high-efficiency rural sewage treatment agent and a method for treating sewage using the same. Background technique [0002] With the continuous improvement of people's living standards, human water consumption is also increasing, and domestic sewage is also increasing. If sewage is discharged into nature without treatment, it will inevitably pollute nature. Therefore, how to properly treat sewage has become an issue. has become a matter of concern for the survival of future generations. Some of the existing domestic sewage treatment uses physical methods that consume more manpower and material resources, and some use sewage treatment agents for chemical treatment, but the cost is high and the treatment effect is not satisfactory. Contents of the invention [0003] The purpose of the present invention is to provide a multi-purpose high-efficiency rural sewage tre...
