Embodiment 1

[0028] Experiment 1: Mix the mass content of 28% of the quadruple three iron, 63% sodium sulfate, 4% polyethylene glycol, 5% sodium chloride in 1 L seawater as an allique agent solution 1;

[0029] Control 2: Mix the mass content of 28% quadricaride, 4% polyethylene glycol, 5% sodium chloride in 1 L of sea water as an allique agent solution 2;

[0030] Control 3: Mixed the mass content of 63% sodium sulfate, 4% polyethylene glycol, 5% sodium chloride in 1 L of sea water is mixed as an allique agent solution 3;

[0031] Blank 4: A polyethylene glycol having a mass content of 4%, and 5% sodium chloride was mixed in 1 L seawater as an allique agent 4 solution.

[0032] 4 parts of the red tide water body having spherical brown cystic algae, each 9L, respectively sprayed the above-mentioned four epitaxial algae solution, the initial concentration of spherical brown vharide in the algae reached 10 9 Cells L -1 The concentration of the red tide algae algae agent in algae is 0.6 g L -1 . ...

Embodiment 2

[0035] The mass content was 46% of the tetramarine, 48% of the potassium hydrogen sulfate, 3% karam, 3% sodium sulfate in 1 L sea water, and prepared a hematontae algae algae solution.

[0036] 6 parts of the red tide water body with red tide bending, each 9L, sprayed in the red tide algae algae agent, the initial concentration of the red tide bend in algae is 10 8 Cells L -1 The concentration of the red tide algae algae agent in algae is 0, 0.1 g L, respectively. -1 0.2g L -1 0.3g L -1 0.4g L -1 0.5g L -1 . After standing for 3 hours, the change of red tide in the algae is observed.

[0037] Different concentrations of alg alg alg alg alcoactivity figure 2 As shown, the results show that when the heave of the red tide is 0.4 g L -1 And above, for biological densities up to 10 8 Cells L -1 The red tide is bending algae removal rate can reach more than 95%.

Embodiment 3

[0039] The mass content was 69% tetramarine, 26% ammonium sulfate, 2% alginate, 3% gluconate in 1 L in 1 L, mix well, prepared a hematontae algae algae solution.

[0040] 6 parts of the red tide water body of East China Sea Origin, each 9L, sprayed it to the above-described algae solution, and the initial concentration of algal fluid Middle East Sea Origin is 10 7 Cells L -1 , The concentration of red tide algae algae agent in algae is 0, 0.05 g L, respectively. -1 0.1g L -1 0.2g L -1 0.3g L -1 0.4g L -1 After standing for 10 h, observe the change in the density of the algae in the Eastern Sea.

[0041] Different concentrations of alg alg alg alg alcoactivity Figure 3 As shown, the results show that when the hematontal crystal concentration is 0.3 g L -1 At the time, 90% of the Original Dioli is removed.

Abstract

The invention discloses an algaecide based on ferroferric oxide activated persulfate and application of the algicide. The algicide for red-tide algae is prepared by mixing, by mass, 28-85% of ferroferric oxide, 6-63% of persulfate, 2-5% of dispersing agent and 3-5% of an auxiliary material. When in use, the algicide is mixed with seawater or fresh water to prepare a uniform solution, the uniform solution is sprayed on the surface of a red tide water body, and the red tide can be effectively removed after natural sedimentation for a certain time. The algicide is efficient, green and sustainable, the problems that an existing heterogeneous algicide needs to be modified, the spraying amount is large, the effect is slow, rebounding is likely to happen, and secondary pollution is likely to be caused can be effectively solved, algae cells are settled by inhibiting the activity of red tide algae, and the red tide water treatment efficiency is remarkably improved through an inactivation-apoptosis-settling algae removal mechanism.

Description

Technical field [0001] The present invention belongs to the control and governance of the red tide. Specifically, the present invention relates to a hematolatene algae algae agent based on the activation of the activated hybrid sulfate based on tetraned iron oxide. Background technique [0002] Red tide, also known as red tide, also known as "harmful algae" or "red ghost". It is a harmful ecological phenomenon in certain plankton, native animals or bacterial eruption proliferation or high gathering in seawater, which will cause fish death, water pollution, and other issues. Since the 21st century, 70-80 times of red tide disasters occurred nationwide have become one of the main marine disasters. Therefore, developing efficient, green, sustainable red tidal algae algae is important and urgent needs [0003] Due to the huge harm of the red tide on the huge harm of economic and human health, the governance measures of the red tide have always been the focus of people's attention and...
