specific Embodiment 1

[0015] A compound agent for removing phosphorus from eutrophic water bodies, specifically including 18 parts of Ca 2 o 2 , 5 parts of polyaluminum chloride, 23 parts of iron powder, 10 parts of Na 2 CO 3 , 5 parts of pH regulator, 27 parts of specific gravity increaser, 22 parts of chelating accelerator, 55 parts of bentonite, 23 parts of clay, 5 parts of mixing agent.

[0016] Preferably, the specific gravity additive is ferrite, and the chelation accelerator is chitin.

[0017] Preferably, the mixing agent is composite clay.

[0018] Add different concentrations of phosphorus-removing compound agents into the sewage, use the control variable method to do experiments, and carry out group numbering to test the optimal concentration of phosphorus-removing compound agents, where 0# is a blank test without adding agents, 1#, 2# , 3#, 4#, 5# dosing concentration is 200mg / L, 400mg / L, 600mg / L, 800mg / L, 1000mg / L respectively.

[0019] The agent is evenly injected into the sewage...

Abstract

The invention discloses a complex reagent for removing phosphorus from a eutrophic water body and a preparation method of the complex reagent. The complex reagent is prepared from 16-20 parts of Ca2O2, 3-6 parts of polyaluminum chloride, 21-24 parts of iron powder, 9-12 parts of Na2CO3, 4-6 parts of a pH regulator, 25-30 parts of a specific gravity additive, 19-24 parts of a chelating accelerator,46-68 parts of bentonite, 16-28 parts of clay and 3-8 parts of a blending agent. The complex reagent is specifically prepared by dosing, mixing, particle preparation, bonding and drying. The complexreagent can effectively remove organic matter, ammonia nitrogen and phosphorus from the water body, and the problem of chromaticity of the water body can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of water body treatment, and in particular relates to a compound agent for phosphorus removal in eutrophic water bodies and a preparation method thereof. Background technique [0002] Rivers and lakes are an important part of the urban water environment system, and their environmental conditions are related to the healthy development of urban water ecology. In existing life, a large amount of untreated sewage and industrial wastewater will be discharged into urban rivers, lakes, etc. Among them, the eutrophication of the water body is serious, the water body will be smelly and polluted, the algae outbreaks will be frequent, and the water ecosystem will be severely damaged. The self-purification ability and maintenance of the landscape water body, and the coordination with related facilities, the existing methods for the treatment of the landscape water body are various, including physical methods, chemical m...
