preparation example Construction

[0059] The preparation method of the AMGR combined bacterial agent and the ratio between the bacteria are the same as the application number 201210008762.7 Example 1, the function of humic acid is a bacteria adsorbent, and its addition amount is added according to the number of conventional bacteria.

[0060] The AMGR combined bacterial agent is used, and the AMGR combined bacterial agent uses humic acid as the bacterial agent ingredient, and the amount of the AMGR combined bacterial agent is used until the microbial concentration of the purified water reaches 0.5×10 5 -1.5×10 5 Each / ml, combined with the plants in the purified water, has achieved the purification of aquatic plants in different ecological niches, and the plants and microbial water bodies have synergistically enhanced purification, and the water purification effect is very good.

Abstract

The invention relates to the field of water quality purification and particularly relates to a biological repairing method of surface water. A water body is purified by combined planting of floating-leaved plants, submerged plants and emergent aquatic plants, wherein the floating-leaved plants include myriophyllum aquaticum, water poppy and water lily; the submerged plants include hydrilla varticillata; and the emergent aquatic plants include papyrus, rushes, clinopodium urticifolium, reeds, canna, Brazilian pennywort, scirpus tabernaemontani, pontederia cordata, cattail, fleur-de-lis, thalia dealbata and rhizoma calami. According to the biological repairing method of surface water provided by the invention, the water body is purified by combined planting of floating-leaved plants, submerged plants and emergent aquatic plants and the polluted water can be purified by the combined actions of precipitation and filtration of aquatic plants and roots of the plants. The water is remarkably clearer than water before the plants are planted. A part of detection indexes of the polluted water source are converted into standard water quality within 2 months. All indexes substantially meet the standard within a half year. The method is short in purifying time, good in purifying effect and stable in purifying effect.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a method for biological restoration of surface water. Background technique [0002] The vast rural areas in South China mainly use natural water bodies such as pond dam surface water or shallow groundwater as drinking water sources. Due to the abundant rainwater and well-developed water system in South China, the random discharge of breeding sewage has seriously polluted the rural water environment and water sources, leading to increasingly prominent problems of rural drinking water safety. [0003] At present, many countries are widely applying biological treatment measures to purify sewage, and rebuilding aquatic vegetation is one of the important measures for lake ecological restoration. After years of exploration, people realized that using higher aquatic plants to purify polluted water bodies is a cost-effective bioengineering technology. However, different plant species ...
