Experimental Study of Diatomite Static Adsorption on TP Removal in Bovine Urine Wastewater

Abstract:

Pollutions of livestock and poultry breeding to the environment have evolved into a serious social problem, while phosphorus is a non-renewable resource. This study aims to not only remove the phosphorus in bovine urine wastewater effectively, but also make it recyclable and reduce the load of the follow-up sewage disposal. Choosing the diatomite as the adsorption material, its adsorption effects and the influence factors of diatomite were investigated by static adsorption method, and the adsorption isothermal curves studied. The results showed that the best adsorption condition was as follows, i.e.,taking 50mL bovine urine wastewater with TP 45.67mg/L, when the diatomite dosage was 3.0g, the pH was 7.0, the adsorption time was at 6.0h with the temperature of 30, TP concentrations could be reduced to 9.86mg/L and total phosphorus removal rate reached at 78.41%. Freundlich equation was better than Langmuir equation in describing the behaviour of adsorption phosphorus on diatomite. It is believed that diatomite is feasible to be used as adsorption agent for phosphorus removal from bovine urine wastewater and this promotes the potential of diatomite being used as sewage treatment materials.
