[0037] S12 Preparation of biological agent: Mix Acupuncture, Chaetoceros, and phosphorus-accumulating bacteria to make a biological agent. The content of phosphorus accumulating bacteria is 0.1~0.3g / L, and the content of phosphorus accumulating bacteria is 0.8~1.5g / L;

[0038] S2 release in polluted water quality areas: detect the phosphorus content in the water quality and determine the release method;

[0039] When the phosphorus content in the water is greater than 0.4 mg / L, choose the feeding method (1): after 12 to 24 hours, 0.1 to 0.2 L of biological bacteria agent is used per square meter of water surface area, and then 100 to 200 g of the obtained in step S1 is added. Dephosphorization of walnut shell particles for 24 to 60 hours;

[0040] When the phosphorus content in the water is 0.3-0.4mg / L, choose the feeding method (2): put 0.1-0.2L of biological bacteria agent per square meter of water surface area for 36-60 hours, and then add 100-200g of the biological agent ...

Embodiment 1

[0059] The automatic feeding system includes a water quality flow data monitor, a storage tank for biological agents, a storage tank for walnut shell particles, a control valve and a main control platform;

[0060] The water quality flow data monitor includes a detection head, which is set every 2 meters apart in the water quality pollution area, and more than one pipeline is arranged at the detection head to communicate with the biological agent storage bucket and the walnut shell particle storage bucket; the water quality The water quality data obtained by the flow data monitor through the detection head is sent to the main control platform; the main control platform sends the corresponding instructions for adding biological agents and walnut shell particles to the control valve according to the received water quality data;

[0061] The control valve is arranged on the pipeline. The control valve includes a valve body and a controller connected to the valve body. The controll...

Abstract

The invention relates to a method for treating water pollution. The invention particularly relates to a method for purifying water by using a composite biological agent. The method comprises the following steps: drying walnut shells and grinding into particles; heating at the temperature of 650-710 DEG C for 7-10 h, cooling to room temperature, adding concentrated sulfuric acid, carrying out a reaction for 0.5-1 h, washing with distilled water cleanly, soaking in a hydrochloric acid solution for 0.5-1 h, cleaning with alkaline water until the pH value is 7, and soaking in distilled water for 10-20 h to obtain walnut shell particles; and mixing synedra radians, chaetoceros gracilis and phosphorus-accumulating bacteria to prepare the biological agent, and determining a corresponding feedingmode according to the phosphorus content in detected water. According to the method, by adding the synedra radians, the chaetoceros gracilis, the phosphorus-accumulating bacteria and the walnut shellparticles, the synergistic phosphorus removal effect is achieved, and the rapid water quality purification method is achieved.

Description

technical field [0001] The invention relates to a method for controlling water pollution, in particular to a method for purifying water with a composite biological bacterial agent. Background technique [0002] At present, the current society has more and more strict requirements on water quality and environmental treatment, and it is impossible to deal with the polluted water immediately. Biological phosphorus removal from sewage mainly utilizes phosphorus accumulating bacteria (belonging to Acinetobacter, Aeromonas and Pseudomonas, etc.) to release phosphorus under anaerobic conditions and accumulate phosphorus under aerobic conditions. Sewage phosphorus removal includes biological phosphorus removal and chemical phosphorus removal, and chemical phosphorus removal includes two necessary processes. First, the soluble phosphorus-containing substances in sewage are converted into insoluble granular forms, and the purpose of sewage phosphorus removal is achieved by removing gr...
