Description

High-efficient algae moisture utilization resource system

Technical Field

The utility model relates to a system, especially a high-efficient algae moisture resource utilization system belongs to water purification treatment technical field.

Background

The eutrophication of the water body easily causes the abnormal proliferation of certain characteristic algae (such as blue algae), so that the transparency of the water body is reduced, the dissolved oxygen content is reduced, the water quality is deteriorated, and further the survival of fishes and other organisms is influenced, meanwhile, as 80 percent of the algae can secrete algal toxins, serious harm is caused to people, animals and organisms, and in addition, the frequent outbreak of the algae caused by the eutrophication of the water body in recent years causes the water body in lakes to lose the utilization value as drinking water, and the harm which is difficult to reverse is brought to the environment.

Currently, as methods for controlling algae, there are mainly physical algae removal methods, chemical algae removal methods, biological algae control methods, etc., and a large amount of money is invested for these methods, but the method has little effect because of the following reasons: the physical algae removal method has the defects of large investment, long treatment period, poor effect and the like due to water diversion, water exchange, adsorption, filtration, mechanical fishing and the like, wherein the filtration and adsorption method is convenient to operate, and the adsorbent is natural and nontoxic, but a large amount of residual algae toxins in the adsorbent easily cause potential environmental, economic and public health risks; the mechanical fishing efficiency is high, but the dehydration rate is lower (less than 10 percent), the energy consumption of the subsequent process is increased, and the equipment investment is large; the operation process of water diversion and water change is complex, a large amount of clean water sources are needed, and the consumption is huge; the chemical algae-removing method mainly comprises the steps of adding a chemical algae-killing agent, a flocculating agent and the like, compared with a physical method, the chemical algae-removing method has less equipment investment, but some algae-killing agents or flocculating agents can ensure that algae cells are subjected to lysis and release algal toxins into a water body, so that the subsequent sewage treatment difficulty is increased, and the human health is harmed. There is therefore a need for improvements in the prior art.

Disclosure of Invention

For solving the above-mentioned a great deal of problems that the physics that current water alga was handled and is adopted removes algae method, chemistry and remove algae method existence, the utility model provides a high-efficient algae-laden water separation resource utilization system.

The utility model discloses a following technical scheme accomplishes: the system for high-efficiency algae-laden water separation and resource utilization is characterized by sequentially comprising the following devices: a sedimentation tank, a primary coagulation device, a secondary coagulation device, an algae separator, a separation water tank, an algae residue buffer, a centrifuge, a fermentation tank and a storage bin.

The primary coagulation equipment and the secondary coagulation equipment respectively comprise a cylinder body with a cavity, a feeding hole and a discharging hole, and stirring blades in the cavity, so that the algae pulp, coagulant and medicament are coagulated by the stirring blades.

The feed inlets of the primary coagulation equipment and the secondary coagulation equipment are respectively connected with the screw conveyer, so that when the screw conveyer is used for conveying the algae slurry, the corresponding coagulant and the corresponding medicament are put into the screw conveyer and then are sent into the primary coagulation equipment and the secondary coagulation equipment to finish coagulation.

The algae separator is a conventional vibrating screen classifier.

And a filter screen is arranged at the bottom of the separation water tank.

A filter screen is arranged in the algae residue buffer.

The centrifuge is conventional equipment, and its discharge gate links to each other with screw conveyer to the sediment of irritating that will centrifuge and send out through screw conveyer.

And a feed inlet of the fermentation tank is connected with the screw conveyor so as to feed the leavening agent into the fermentation tank for fermentation by the screw conveyor.

And a spiral conveyor is connected between the discharge hole of the fermentation tank and the feed inlet of the storage bin.

The utility model has the advantages and effects of: adopt above-mentioned scheme, make whole production accomplish in automatic process, especially through carrying out the one-level to the algae thick liquid, after the second grade coagulation treatment, can furthest promote algae separation effect, reduce the separation time, when carrying out the algae separation through the algae separating centrifuge, accomplish high-efficient separation, and showing and reducing the energy consumption, the separation water of separating out goes out the water continuous, water quality can discharge up to standard, the algae sediment after the separation is through centrifugal dehydration after, carry out fermentation treatment and become algae sediment slowly-releasing fertilizer, let the algae sediment realize waste utilization, avoid secondary pollution. The whole algae separation and resource treatment process can realize automation and intellectualization, reduce human interference, stably control the product quality and uniformity, improve the production efficiency and the product yield, and reduce the energy consumption so as to meet the requirements of the water area treatment capability, the water quality stability, the formula applicability, the energy conservation, the consumption reduction and other technologies and processes in the large-scale industrial production of the algae separation in the water area. It is an ideal processing method and system.
