The compound bioflocculant comprises cation starch, sodium carboxymethylcellulose and any one or two of diatomaceous earth or modified clay. The environment-friendly compound bioflocculant for terrigenous sewage and off-shore marine polluted water disclosed by the invention is non-toxic, low in cost, and free from secondary pollution, is an environment-friendly sewage treating agent, and has great development value and application prospect.
Description
Technical field
The invention belongs to sewage treatment area, particularly a kind of environment protection biological composite flocculation agent for Lu Yuan sewage and coastal ocean polluted-water.
Background technology
The unordered discharging of China's Lu Yuan sewage has a strong impact on urban ecology and resident living environment.Therefore sewage disposal technology seems extremely important.But it is unsatisfactory that the present disclosed sewage-treating agent of China is processed above-mentioned sewage effect, and certain treatment effect is perhaps arranged, but secondary pollution and certain biological accumulation toxicity can occur; Adopt polyacrylamide, polyaluminium sulfate etc. such as sewage flocculant commonly used at present more.
China's immediate offshore area overall situation is severe simultaneously, and it is comparatively serious to show as the Offshore Ecology environmental damage, and most of Marginal Sea Ecosystems is in subhealth state or unhealthy condition.Serious, the frequent occurrence of the various meteorologicdisasters of initiating species, water quality deterioration, eutrophication, ocean environment are degenerated thus, particularly dissolved oxygen (DO) content decrease, species diversity are destroyed in the water body, a large amount of marine cultured animals are dead, and the human food prods is reached safely healthy causing a significant threat.
Oceanic area such as the bad four class water quality in offshore waters, the South Sea accounts for 1/3rd of the South China Sea total area, and the eutrophication of Nanhai District coastal waters water body causes frequent occurrence, causes regional Dissolved Oxygen in Water (DO) content decrease, a large amount of fish kills.The algae toxin of some malicious algae secretions, easily by the shellfish enrichment, human edible shellfish causes poisoning, and causes a significant threat for human food safety.Simultaneously, China also exists the trade effluent that is polluted in a large number to process.
Carry out at present sewage disposal and much use sewage treatment flocculating agent, the research of sewage treatment flocculating agent is take efficient, cheapness, environmental protection as target.Environmental protection is to develop pointedly nontoxic or the low toxicity efficient flocculant, make its tap water and other relevant with physical activity with water treatment in bio-toxicity and residual quantity no longer cause secondary pollution.
Composite flocculation agent has also at home and abroad obtained carrying out widely because combining inorganic and organic advantage, has become the focus of present flocculation agent research, and safe, nontoxic, efficient microbial flocculant more has the trend that replaces traditional flocculant.
Wastewater treatment in China should have been closed the theme of beautiful China just at present, and the environment protection biological composite flocculation agent that is used for Lu Yuan sewage and coastal ocean polluted-water commonly used but exists native toxicity and drug residue and causes the problem of secondary pollution.
Summary of the invention
For overcoming above-mentioned technological deficiency, the invention discloses a kind of environment protection biological composite flocculation agent that is used for Lu Yuan sewage and coastal ocean polluted-water of efficient, environmental protection.
Environment protection biological composite flocculation agent for Lu Yuan sewage and coastal ocean polluted-water disclosed by the invention contains cationic starch and Xylo-Mucine, and in the diatomite, modified clay one or both.
One or both weight ratio is 1～50:5～100:5～100 in described cationic starch, Xylo-Mucine, diatomite and the modified clay.
Further, one or both weight ratio is 5～20:10～50:15～50 in described cationic starch, Xylo-Mucine, diatomite or the modified clay.
Further, one or both weight ratio is 10-15:20～30:20～30 in described cationic starch, Xylo-Mucine, diatomite or the modified clay.
Cationic starch in the present invention is to introduce uncle's amino or quaternary ammonium group in starch polymer, gives the starch cationic characteristic.The positive charge of cationic starch makes it be combined with electronegative matrix, and can and remain on the matrix other electronegative additive absorption.Because the pollutents such as most of subparticle and colloid have negative charge in industrial sewage and the pollution of the sea water body, so cationic starch can be processed the electronegative pollutent in the polluted-water preferably.Xylo-Mucine is the abundantest natural macromolecular material of originating, and it is easy to be dispersed in water into transparent colloidal solution, can occur precipitation when pH is 2-3, meets polyvalent metal salt and also can react the generation precipitation.Diatomite is rich in organism, is one of food source of Microbial Communities in Activated Sludge, and simultaneously diatomaceous Calcium of intensifiens can play the effect of some heavy metal elements of displacement, and isolated free ca can promote again the deposition of Ca, Mg and Fe in the sewage etc.
The present invention has following effect: (1) environment protection biological composite flocculation agent for Lu Yuan sewage and coastal ocean polluted-water of the present invention is nontoxic, and is efficient, cost is low, does not have secondary pollution, is environmentally friendly sewage-treating agent; (2) the environment protection biological composite flocculation agent for Lu Yuan sewage and coastal ocean polluted-water of the present invention obviously is optimized the water-quality guideline of coastal waters sewage and industrial sewage, has than great development value and application prospect.
