Abstract
A water cleaning agent is prepared from aluminium polychloride, iron polychloride, polyacrylamide, magnesium chloride and fluorescent whitening agent through mixing. Its advantages are high effect on removing SS, COD, BOD, nitrogen, and phosphorus, less dosage, short period, and no secondary pollution.
Description
Technical field
The present invention relates to a kind of water purification agent, more specifically relate to a kind of sanitary sewage disposal, reclaimed water processing, industrial sewage processing.
Background technology
The body eutrophication of China is more prevalent and serious, not only most lakes, river, small reservoir, nutrient laden is nothing to be surprised at already, nowadays connect great river, great river, ocean, also occur the eutrophication phenomenon repeatedly, eutrophication wawter bloom phenomenon takes place as first tributary, the Changjiang river, Han River, Taihu Lake, Guangzhou, ALONG COASTAL FUJIAN many places, algae wind is long, marine red tide, too fast with China's rate of economic development, medium and small sized enterprises are many; Equipment, technology fall behind, and poor to protecting the water resources pass to read, even big and medium-sized cities are also very low to the waste water control ability, the sewage treatment that we use now is divided into two kinds: first kind is one-level processing (mainly to be precipitated as the master); Second kind is second-stage treatment (mainly with bioremediation).
1, one-level sewage water treatment method: generally also using now, the one-level sewage treatment process mainly is that the mud in the precipitation sewage is main, and clearance can not reach state sewage emission standard substantially between 25%-30%, a large amount of nitrogen in the sewage, phosphorus; Be discharged into river, ocean, small reservoir, caused the body eutrophication phenomenon.
2, B-grade sewage treatment process: mainly reach the water purification purpose, but bioremediation can not effectively be removed total nitrogen, total phosphorus, does advanced treatment in requisition for other method with organism in the biological activity mud removal sewage.
Summary of the invention
The object of the present invention is to provide a kind of water purification agent (flocculation agent), with polymerize aluminum chloride, poly-ferric chloride, polyacrylamide, magnesium chloride, formulated at the adding recombiner in proportion, technology is easy, purifying water effect is good, and can effectively remove SS (suspended solids), COD
Cr(chemical oxygen demand (COD)), BOD
5(biochemical oxygen demand (BOD)), total nitrogen, total phosphorus reduce the harmful organic substance inorganics, have reached the purpose that middle water reuse, various sewage disposal reach discharging, improve water body environment.
In order to achieve the above object, the present invention takes following technical measures, with polymerize aluminum chloride, poly-ferric chloride, polyacrylamide, magnesium chloride, adds recombiner by a certain percentage, makes particulate state, adopts polynary weight packing then, it is characterized in that; Polymerize aluminum chloride 60%-99%, poly-ferric chloride 0.1%-10%, polyacrylamide 0.5%-10%, magnesium chloride 0.4%-20%, mix the back and add white dyes 0.001-1%, stirred at normal temperatures 5-50 minute, make granular substance, after carry out polynary weight packing, under different situations, be added in the water body in proportion.
The mechanism of action: product of the present invention drops in the water and dissolves, and forms the bridge formation adhesive effect, and the flocculation particle is big, and flocculation group is big stable, and bonding adsorptive power is strong.
Reaction mechanism: product of the present invention dissolves the back and forms a large amount of complex compounds in water body, improve water column structure, reaches the purification purpose.
The example explanation:
Example 1: the present invention is to the influence of former life sewage purification, the example explanation
Example 2: the present invention is to B-grade sewage treatment plant, and the water purification after the processing influences, the example explanation
Comprehensive above-mentioned experiment shows, can effectively purify the SS (suspended solids), the COD that remove in the water body in the water of the present invention after former water of sanitary sewage and second-stage treatment
Cr(chemical oxygen demand (COD)), BOD
5(biochemical oxygen demand (BOD)) total nitrogen, total phosphorus, ammonia nitrogen, kjeldahl nitrogen.
The present invention compares with existing technology and has the following advantages: technology is easy, action time is short, consumption is few, the settling time is fast, reduce the spending of sewage disposal factory site working cost and civil engineering costs, cost is low, purify water, can reach the reuse water standard except that drinking, the conserve water resource, easily decompose, no residual hazard does not have secondary pollution, for waste water control provides good guarantee.
